Geyser junkers wr 275 1p instructions. How to properly use and repair Junkers geysers? Typical malfunctions of the Junkers geyser

Geysers are designed for heating water in apartments and houses that do not have a central hot water supply. The devices are easy to use, safe, and allow you to adjust the degree of heating.

All Junkers water heaters are adapted for use in Russia and have a number of advantages:

adaptation to pressure in Russian gas pipelines of 13 mbar. In Europe this figure is 20 mbar. Unadapted devices under such conditions will be less productive;
adaptation to water supply pressure. Russia is characterized by low water pressure, especially in multi-story buildings. The Junkers geyser operates stably at a pressure of 0.1 atm;
high performance. The devices heat 11-16 liters of water per minute;
cold water is mixed in the mixer;
flame modulation - automatic change in power depending on the volume of water flow;
safety;
German assembly quality;
two years warranty;
long service life.

Types and prices

Columns are divided into three types according to the ignition method:

Series B - there is no constantly burning igniter. Ignition is powered by two batteries. The dispenser turns on automatically, there are several safety systems: traction control, fuse, ionization flame control. Water flow and temperature are regulated depending on the water pressure in the water supply. There is a fault indicator. Junkers B series is made of copper high quality and will last at least 15 years. Models: WR 13 V, WR 15 V, WR 10 V (minMAXX).

Series P – piezo ignition. The pilot light is constantly on. Power and water flow are regulated separately. Thermoelectric flame control. Models: WR 13 P, WR 15 P, WR 10 P (miniMAXX)

Series G – HydroPower ignition technology. Minimum water pressure 0.35 atm. There is no burning igniter; ignition is carried out from a hydrodynamic generator. Gas water heater G series provides hot water 1-3 water points at the same time. Models: WR 13 G, WR 15 G, WR 10 G (miniMAXX).

All models are available in two sizes: standard and mini. The equipment of both versions is the same, the only difference is in dimensions. The price depends on the size of the device and the need for delivery and installation. Average cost for Moscow is reflected in the table.

Model range					Price, rubles
standard		Height, mm	Width, mm	Depth, mm	Price, rubles
WR 350-3 KDP	WR 13P				8 200
WR 350-3 KDB	WR 13B				10 700
WR 350-3 KDG	WR 13 G				11 400
WR 400-7 KDP	WR 15P				9 600
WR 400-7 KDB	WR 15B				12 000

WR 275-1 KDB	WR 10B				10 100
WR 275-1 KDG	WR 10G				10 600

If buying a new model is beyond your means, you can find a good used device. It costs an order of magnitude cheaper.

Possible breakdowns

The design of Junkers devices is one of the most advanced today. But breakdowns still occur due to correct operation, voltage surges, scale formation, housing corrosion. Manufacturing defects are eliminated free of charge at all service centers. On average in Moscow, the cost of repairing a Junkers geyser is 2,000 rubles. If you call a technician to your home, it will be more expensive; if you take the equipment to the service yourself, it will be cheaper.

Typical faults:

1. The ignition wick goes out. The cause may be a breakdown of the thermocouple, valve or flue gas sensor;

2. The water is not heating. The reason is a breakdown of the heat exchanger;

3. The water heater is noisy and overheats. The reason is a broken radiator or clogged with scale;

4. The housing is leaking. Problems with the seal or heat exchanger;

5. The ignition spark goes out. Reason: the flame controller is broken;

6. Spontaneous shutdown.

Is it possible to carry out repairs yourself? Certainly! To do this you need:

establish the cause of the malfunction;
have original spare parts;
have special equipment for diagnostics and repairs;
undergo training on working with gas equipment;
a lot of time;
funds for new device in case of force majeure.

Therefore, troubleshooting any geyser malfunctions should be carried out by a specialist with special skills and knowledge in this area. Repairs must comply with GOSTs and standards for this type of work. Only in this case can you count on long-term and reliable operation, eliminating the risk of explosion and gas leakage. Original spare parts can be purchased from Bosh dealerships. So, a new hydraulic fitting will cost about 7,000 rubles, an igniter – 500 rubles, and an electronic ignition unit – 5,000 rubles.

The Junkers geyser is a product of the German concern Bosch. Like all German technology, these devices are easy to use, reliable, durable and economical. natural gas.

About the company

Trading Junkers brand joined the giant company Bosch Gruppe in 1932. And the history of the brand began back in 1895, when the German engineer Hugo Junkers, an inventor and industrialist, opened a factory for the production of water heating devices. Junkers himself patented about two hundred inventions - this is a record for its time. The company has introduced piezo ignition since 1968. Then a column with ignition from 2 batteries was released. Ten years later, Junkers launched the world's first wall-mounted combi boiler with continuous power control. The brand is known for its turbocharged speakers - not many manufacturers produce them. Bosch Thermotechnology is the world's largest manufacturer heating equipment, occupies a leading position in Europe.

Flaws

Even the famous German quality cannot completely eliminate the shortcomings arising from the design features of water heaters. Cons of Junkers speakers:

Almost all modifications are characterized by increased noise.
After a few years (5-6), the heat exchanger begins to fail and leaks may appear.
The joints have to be sealed, and the gaskets that are equipped with the Junkers models are not enough to eliminate leaks.

Experts claim that the cause of problems with the heat exchanger is scale. The operating instructions recommend that in order for the equipment to function properly in Russian water supply conditions, it is necessary to install an additional water filter. This will increase the service life of the device to 10-12 years. Not all consumers are attracted to this solution - they have to regularly change cartridges. Many users also do not want to take a bath in water that has passed through a magnetic filter.

Advantages

Despite the serious disadvantages of Junkers water heaters, they are in demand on the domestic market, as they offer potential buyers a large list of advantages:

Adaptation to domestic gas pipeline systems. In the Russian network the pressure is 13 mbar, in Europe - 20 mbar.
Work at water pressure from 0.1 atm.
High productivity - heats water at a speed of 11-17 l/min.
There is a flame modulation system - the power automatically changes, ensuring stability of the temperature of the heated liquid.
Reliable security system.
Reasonable price.
Warranty - 1 year. Service life - 10-13 years.

How much do they cost? The price of Junkers models depends on the size - all other characteristics of the models are the same. The manufacturer offers two versions: mini and standard. Cost - from 7,000 to 11,000 rubles.

How to choose?

The main difference in the Junkers models is the ignition method. Water heaters have not been lit with matches for a long time; there are more advanced ways to create a fire:

The “P” series devices use piezo ignition - the most popular option. The device turns on with one click of a button. Such versions have another important advantage - you can set the water temperature. The pilot light is constantly on.
The “B” series heaters have electric ignition - in this case, the device lights up using batteries. This option is more expensive, but gas is also consumed more economically - there is no need for a constantly burning igniter. The device turns on automatically when the coolant starts moving. Such versions allow you to save fuel and use the device comfortably.
In devices of the “G” series, Hydro Power technology is used for ignition - a special generator, there is no burning igniter.

Safety

Gas - source increased danger. Gas equipment, having a multi-stage safety system, prevents possible emergency situations. All processes are controlled by automation, which, at the slightest hint of a problem, will prevent danger and cut off the flow of gas. German speakers provide protection:

from the extinction of fire;
from lack of traction;
from reverse draft;
from overheating.

Installation and maintenance are the work of professionals.
Periodic cleaning of the igniter and radiator is necessary.
It is not advisable to install very high temperature heating - this promotes accelerated scale formation.
If the water is very hard, the device needs a special device to prevent scale formation.

What problems happen?

More than half of all breakdowns occur due to violation of operating rules. All other malfunctions are associated with electrical problems, poor water quality and corrosion. If a manufacturing defect is detected, the device is sent to a service center to fix the problem free of charge. Paid repairs cost approximately 1000-2000 rubles. It is more profitable to take the water heater to a service center, since calling a technician will cost more. The most common faults:

The device cannot be ignited. The pilot light comes on and goes out after a couple of seconds. The reason is a breakdown of the thermocouple, valve or combustion products sensor.
The water is not heating up. The probable cause is a breakdown of the heat exchanger. Perhaps a lot of scale has formed in it.
The device is noisy and overheats. The reasons are the same as in the previous paragraph.
Water loss. Reasons: the heat exchanger is damaged or it’s time to change the seal.
Popping noises are heard during operation. The cause may be either too much or too little gas pressure. In any case, professional cleaning and adjustment will be required.
Smell of gas. This problem needs to be treated especially carefully. The first step is to turn off the gas valve and immediately ventilate the room, then call the gas service.

To fix the problem yourself, you need to:

establish the exact cause of the breakdown;
buy original spare parts;
prepare the equipment necessary for repairs;
study the rules for eliminating a specific malfunction and strictly follow the instructions of specialists.

Before turning on the Junkers dispenser after replacing a faulty part, you should make sure that the fasteners are firmly fixed - gas leakage must be excluded. DIY repair possible if you have experience and knowledge of the design and operation of the equipment. Only original spare parts should be used. Buying new hydraulic fittings will cost 7,000 rubles, you will have to pay 500 rubles for the igniter, and about 1,000 rubles for the traction sensor. The cost of an electronic ignition device is 5,500 rubles.

Dismantling the Junkers gas water heater

To repair a unit, perform preventative cleaning or replace a part, you need to disassemble the device in parts. The disassembly procedure is as follows:

Remove the handle located on the water block. Set the gas regulator to the central position, unscrew the screws - they are located at the bottom of the housing. Junkers may have clips instead of screws. Now you can remove the housing.
Unscrew the screws securing the chimney cap to the housing. Then - self-tapping screws from the strip screwed to the cap - it is needed to fix the heat exchanger.
Sequentially remove the traction and temperature sensors and disconnect the wires from them. There is a difference between Bosch and Junkers speakers: with the former, the wires from the traction sensor can be easily removed, with the latter, they are secured by soldering and cannot be removed.
Disconnect the cap from the heat exchanger and housing and remove it. Be careful when removing pipes. The pipes have rubber seals - it is advisable to replace them with new ones during assembly, since they tend to age and dry out.
Disconnect the wick tube from the burner.
To remove the burner, you need to unscrew the screws and, pressing the thermocouple with a screwdriver, remove it from the burner body.

An easy-to-use, German-made Junkers geyser is designed for use in apartments or private houses where there is no centralized hot water supply. The units are divided into several classes according to the type of ignition and power. All of them are adapted to work in Russian conditions, capable of operating at critically low pressure in the system (down to 0.1 atm), which is especially important for multi-story buildings.

Before choosing a device, you should study all the characteristics in detail, otherwise you may make a mistake and purchase the wrong option.

Types of geysers Junkers

All modifications of Junkers geysers are equipped with different types igniter

Junkers Version "B"

Bosch Therm 4000 OW 10-2B

The burner is ignited using 2 batteries. The water heater starts at an automated level. Eat complex system responsible for operational safety:

traction control;
safety valve;
ionization fire setting.

Water pressure level and temperature regime configured based on the flow in plumbing system. This version has a malfunction indicator that indicates the need to repair the Junkers geyser.

Based on user reviews and manufacturer statements, the unit in this series is capable of serving properly for more than 10 years. This classification includes all types of Junkers WR geysers, including Min-Maxx and Junkers WR 10, but with the prefix “B”.

Junkers "R"

In these versions, piezo ignition is installed, the igniter will always be ignited. Water pressure and flow can be adjusted separately. Models WR13-P, 15-P, 10-P have a thermoelectric device that controls the flame level.

Junkers "G"

Class “G” units have Hydro Power technology and are capable of operating at a pressure of 0.35 atm. The burner is ignited by a hydrodynamic generator. Class “G” devices operate at three water intake points. Modifications: WR 13-G, 15-G, 10-G.

Cost of units

Modifications of two versions are released on the market - standard and mini. They differ in size, all other parameters are completely identical. The cost of devices depends on the dimensions, the need for transportation and installation. On average, the price of devices is equal to the following indicators:

Versions by size		Dimensions			Cost, rub.
Standard	Miniature	Height, cm	Width, cm	Depth, cm	Cost, rub.

Each device comes with an instruction manual, which specifies detailed information about how to turn on the gas water heater, configure it and even install it. But it is recommended to entrust the installation to specialists from the gas service. Otherwise, you can make a mistake that will harm not only the water heater, but also the health of the user.

Common problems

More than 60% of breakdowns occur due to non-compliance with operating rules, the remaining percentage is attributed to power surges, poor water quality and corrosion. Manufacturing defects are not included this list, since it can be fixed free of charge by sending the equipment to a service center.

Despite the fact that Junkers are very high quality and reliable among their competitors, breakdowns sometimes occur. They are associated with voltage surges, housing corrosion, and scale formation. Factory defects are eliminated free of charge

As for paid repairs, approximately 800-2000 rubles will be required for the services of a specialist, depending on the complexity of the work. But here it should be borne in mind that it is more profitable to transport the water heater to the service center yourself, since a visit from a Junkers geyser repair technician is even more expensive.

Common malfunctions that users often encounter during equipment operation:

A few seconds after starting the water heater, the wick goes out. The main reason for this situation will be the failure of the thermocouple, valve device, or combustion product sensor.
The water does not heat up. In this case, most likely the heat exchanger has broken down or a large layer of scale has formed in it.
The device began to make loud noises and overheat. The reasons are completely similar to the previous paragraph.
Water leak. The integrity of the heat exchanger is compromised or the seal requires replacement.

To fix the problem yourself, first of all you need to carry out the following manipulations:

establishing the exact cause of the breakdown;
purchase of original spare parts;
preparation of equipment that may be required in the process repair work;
studying the rules for troubleshooting and following the recommendations of specialists.

After replacing the broken part, before lighting the Junkers geyser, you need to make sure that all fasteners are firmly fixed and there will be no gas leakage when turning on the burner.

Water heater repairs may only be carried out independently if you have the necessary experience. Also, only original parts should be used. You can purchase spare parts from an official Bosch representative. For example, a new hydraulic fittings will cost up to 7,500 rubles, an igniter - 400-500, electronic device for ignition it will cost 5500 rubles.

Pros and cons of Junkers geysers

Junkers geysers are considered quite common; they are often found in private homes and country houses. But even modern units made on the basis of leading technologies have some disadvantages. The main disadvantages are the following nuances:

increased noise level - this factor applies to almost all modifications;
after 5-6 years, problems with the heat exchanger begin, water leaks appear;
All joint areas require additional sealing; the supplied gaskets are not enough to eliminate all leaks.

According to water heater repair specialists main reason the appearance of the listed nuances is the formation of scale. The manufacturer claims that this equipment can be used in Russian conditions only with the installation of an additional water filter. In this way, you can increase the resource to 10-12 years.

But here other nuances arise. Firstly, regularly replacing cartridges is considered quite a troublesome task, and secondly, doubts arise about the usefulness of taking baths with magnetized water. Russians are quite satisfied with the service life of water heaters of 10-13 years without the use of various filter systems.

But despite such categorical disadvantages, Junkers Control equipment has a large number of advantages, which include:

modifications are adapted to the pressure in the domestic gas pipeline system of 13 mbar, when in Europe the figure reaches 20;
water heaters are able to function in combination with a water supply system in which low water pressure is from 0.1 atm;
the units have increased productivity and are capable of heating 11-17 liters of liquid per minute;
the equipment is equipped with a flame modulation system, when automatic power selection occurs depending on water pressure;
high degree safety and affordable cost.

To all this, you should also add the operating life of the water heater equal to 10-13 years and a warranty of 24 months.

VIDEO: How to backflush water pipes and water heaters without chemicals

The device has both advantages and disadvantages. The advantages include the following characteristics:

equipped with flame modulation;
increased security;
adaptability for use in Russia;
wonderful appearance.

Thanks to its design, Junkers will fit perfectly into any interior. The device operates at a gas pressure of 13 Mbar. This pressure is present in all gas pipelines in Russian homes. If we compare it with European pressure (20 Mbar), then it is significantly lower, which creates problems when purchasing other geysers. The device operates effectively in multi-storey building, where the pressure in the water supply system is very low (works from 0.1 ATM.)

Junkers has increased safety and low cost compared to its analogues. When the water pressure changes, the device will automatically select the power at which water heating will be optimal. The device is assembled by German designers and has a 2-year warranty. At correct installation and operation, the device can last more than 13 years.

Among the disadvantages are the fact that in most modifications of Junkers geysers there is an increased noise level. During operation of the device, problems appear with the heat exchanger and leaks in the seals, which creates a risk of damage flooring under the gas water heater or completely flood your neighbors.

Junkers speaker design

Semi-automatic- The company began producing speakers back in 1968. During operation, a pilot burner is used. Ignition is carried out using a piezoelectric element. The main burner turns on when the DHW tap is opened.
Automatic - powered by batteries or a hydrogen generator. The series presents simple geysers Junkers with an open combustion chamber, and multifunctional models with modulated power. The performance of the burner varies depending on the water pressure.

Possible faults

Of course, the operation of any equipment does not always go smoothly; you should be prepared for anything. Fortunately, a significant part of the possible malfunctions that occur with a Junkers geyser can be easily resolved on your own.

There are actually many reasons why the burner does not light.

It may turn out that both the inlet and outlet pipes were initially installed incorrectly. In addition, the water supply may be disrupted.
Possible problems with traction. When the chimney is dirty, combustion products do not escape, but accumulate inside, which slows down the operation of the equipment. Craving also suffers due to the lack of fresh air, for example, when the window is closed.
It happens that the chimney becomes blocked, and this creates a potentially dangerous situation. We urgently need to turn off Junkers and call specialists.
If the pilot flame goes out, this indicates that the protective relay requires replacement.
It may simply turn out that the burner does not light because the battery is discharged, and therefore the automatic ignition system does not function. You will have to disassemble the front panel and charge it yourself or replace the battery.
Low pressure in the main leads to poor water supply, which again leads to operational problems.
The wick goes out when the flame is uneven. As a result, the main burner also turns off. To solve this problem, simply clean the device.

Sometimes the Junkers speaker does not light up, and sometimes the device turns itself off.

The first reason is that the batteries have become unusable.
The second reason is that it is necessary to change the membrane, which has become deformed or torn. It's good when the repair kit contains a replacement.
Next possible option The problem is that one of the control sensors does not work or the microswitch is worn out, this can be determined by the absence of a characteristic click.

In addition, the igniter may become clogged from the inside, which can be easily fixed by cleaning. An abundance of rust, dirt in filters due to poor quality water and electrodes leads to similar consequences. Finally, improper installation, a closed tap on a gas pipeline, and problems with wires are also common causes of service interruptions.

There are several more common cases. If there is no spark in a device with auto-start, then perhaps there is no ionization current, which means water is not flowing. The spark goes out when the flame controller is broken. If the column does not heat water, the reason may be perforation of the water block membrane, contamination of the tubes or improper assembly, but most often, a breakdown of the heat exchanger.

When the water heater makes excessive sounds and gets hot, this indicates that the radiator is broken or clogged with scale.

A leaking housing is a consequence of problems with the heat exchanger or seal.

You can learn how to light a Junkers gas water heater from the video below.

Common breakdowns

Often the device breaks down due to improper use. It happens that this happens due to corrosion, poor water quality and electrical surges. If a defect is discovered after purchase, it will be repaired free of charge at the service center.

Paid repairs will cost approximately 1,500 rubles. The price depends on the complexity of the breakdown. It is recommended to take the device to the service yourself in order to save on delivery or calling a private technician. Most frequent malfunctions are:

water leak;
overheat;
the occurrence of loud sounds emanating from the device;
the water does not heat up;
The sensor stopped working.

Basically, these breakdowns occur due to the formation of a large layer of scale. In order to repair the device yourself, you need to determine the cause, purchase original spare parts, follow the recommendations of specialists and study the basic rules for repairing this type of boiler.

After repairs, you must make sure that all fastenings of the device are correctly secured and that no gas leaks occur during operation. Repairing the device yourself is only permitted if you have such experience. Only original spare parts purchased from Bosch should be used.

Signs that the wick igniter is not working properly and why it goes out

In speakers with piezo ignition, the igniter must burn constantly, because when the tap opens hot water, it should ignite the main burner. The extinguishing of the igniter disconnects the column from the gas supply so that gas does not accumulate inside the device.

The pilot light may go out if:

It is clogged with debris or dust.
A stream of air acted on him from outside.
The thermocouple has burnt out or worn out.
There is no draft in the chimney.
The traction sensor has failed.
Broke solenoid valve.
No air access.

If the gas water heater does not turn on at all, read another article.

The most common cause of igniter extinguishing is a faulty thermocouple. Its main function is to block gas access to the column if the device is operating unstable. As soon as the pilot light goes out, the thermocouple detects the lack of heat and gives a signal to turn off the gas. However, if the thermocouple itself is damaged, it causes the wick to fade.

An equally common situation is when dust or some kind of debris gets into the igniter nozzles. Their diameter is very small, so even slight contamination can prevent the igniter from burning, resulting in the thermocouple not heating up enough.

The color of its flame indicates that there are problems with the igniter and it can go out at any moment. A normally functioning wick will have a flame that is 90% blue and may include some red flecks, and the tip may be yellow. If the pilot flame is predominantly yellow or orange, the wick is not working properly and the thermocouple will not heat up enough, causing the burner to go out.

About others possible reasons For igniter damping, see the following video.

The principle of operation of the gas water heater

To better understand the reasons why a geyser may go out, you need to understand the operating principle of such a device. Only after studying the essence of the process of heating water with a similar device can you talk about its malfunctions.

Before you start using the gas water heater, you must read the instructions

There are many manufacturers producing geysers. These are the world-famous expensive Bosch and Zerten, and more budget analogues such as Oasis, Vector, Neva Lux 5514, Beretta, Avangard, Astra, Mora speakers. In any case, the basic operating principle of all the above models is the same. The only thing is that there are automatic and semi-automatic speakers, but the difference between them is insignificant.

Main elements of a gas water heater:

Gas burner is one of the essential elements geyser.
A heat exchanger is located above the gas burner. It is a tube bent into a spiral, through which water flows and heats up.
The ignition device can be electronic, and ignite from a button, or have a pilot light or wick that never stops burning. Old gas water heaters had to be lit with matches, and modern models A piezo ignition is installed, activated by pressing a button.
The water-gas unit includes two components: a membrane and gas valve. When you turn on the water, the membrane bends and opens the gas valve, thereby ensuring gas flow into the burner.
The safety automation includes sensors and a solenoid valve. If there is any malfunction, the electromagnetic sensor closes the valve and the column turns off. The kit also includes a thermocouple, which is activated when the pilot burner is turned off.

Thus, there is no reservoir for storing water in geysers. Passing through the heat exchanger, the liquid heats up in a matter of seconds, thereby ensuring a constant supply of warm water to several water intake points at once.

Natural gas is used to heat water with a gas water heater. Such raw materials cost several times less than electricity, which reduces the popularity of geysers.

Knowing the structure of the gas water heater, you can understand why it goes out. We will describe to you the main problems and tell you what to do in this case.

Description of different types of Junkers brand speakers

If you are interested in the Junkers geyser, then you should consider the features of different models that belong to certain series. For example, Series B equipment does not have a constantly lit pilot light. Ignition is carried out from two batteries. The column turns on automatically and has several safety and traction control systems.

You can use the ionization flame control functionality and rely on the fuse to work. The temperature and flow of water are regulated depending on the water pressure in the water supply. You can find out about malfunctions by reading the display. The speakers in this series are made of high quality copper, which can last for 15 years. The Junkers geyser may also belong to the P series, the equipment in this case has piezo ignition, and the igniter will burn constantly. Flow and power are regulated separately. The flame intensity is controlled through a thermoelectric system. In equipment that belongs to the G series, the manufacturer has provided ignition technology. The minimum water pressure at which the column will operate is 0.35 atm. The device does not have a burning igniter, and ignition is carried out using a hydrodynamic generator. If you choose one of the G series columns, you can count on the fact that you can immediately connect the equipment to three water intake points. All models can have a minimum or standard size. Both versions have the same equipment, and the only difference is in dimensions. The cost depends on the device and the need for transportation and installation.

Why does a gas water heater go out and how to deal with it yourself?

If the speaker does not work well, turns off quickly and turns on slowly, then you may be faced with one of the problems described above. In this case, you need to find out the reason, and if it is not very serious, try to eliminate it yourself. Let's talk in more detail about several of the most common problems that you can cope with without the help of a specialist.

If the gas water heater goes out, it cannot be used.

The most common problems due to which the wick in a gas water heater does not burn:

If there is no draft in the chimney, there may be two reasons: a clogged chimney and poor ventilation. In the first case, you will need to clean the chimney. You can do this yourself or use the services of a specialist. However, there is another equally common problem. The fact is that nowadays most apartments are equipped with airtight plastic windows, which limit the ventilation of the home. In this case, you need to install a special supply valve, which will ensure proper air circulation; if this is not done, the column will only work when the windows are opened. If you have a supply valve, but suffer from the column constantly turning off, then check the draft by holding a lit match to the inspection window. If the flame does not deflect, then repeat the experiment with the chimney. If there is draft in the chimney, then the heat exchanger in the columns is cleaned, if not, then the chimney itself.
When the burner itself goes out, most likely the reason is a strong gust of wind. To prevent this from happening, do not open windows in windy weather. To resume operation of the device, you need to turn it off and on again.
The column may also go out due to overheating. Such a nuisance can occur from mixing hot water with cold water or due to the formation of scale in heat exchangers. To prevent this from happening, you need to regulate the temperature by changing the water pressure, or using the regulator on the column. You also need to constantly clean the heat exchanger from scale using special products.

These are the three most common reasons why both Chinese and branded speakers may not work. With some simple manipulations, you can deal with this problem yourself.

Installation and connection

It is better to entrust installation and connection to a specialist who has been trained in working with this type of equipment. In addition, he will be able to suggest which original spare parts are worth purchasing, diagnose the equipment and prevent any malfunctions from occurring. However, even a professional must follow the instructions that are sold along with the product itself.

The column is usually mounted in a warm room near the chimney so that the supply of combustion air is not obstructed. Need for additional protection There are no flammable surfaces. The device is installed in compliance with the required gaps separating it from the wall and furniture. The room temperature should be positive.
First of all, the casing is removed, then it tilts towards itself and rises up. Having connected Junkers to the gas network, you need to install shut-off valves as close to installation as possible. Before connecting to the water supply pipes, they will need to be thoroughly washed, otherwise sand, lime and other contaminants will lead to a delay in water supply. Both pipelines (gas and water) must be ideally combined with the parameters of the column.
To avoid blockages, it is necessary to install protective filters.
The column is attached to the wall using brackets. It should not rest on water or gas pipes. If the speaker has an electric ignition, you will need to insert two batteries with a power of 1.5 Volts.
At the end of work stopcock and the water valves are closed, and the operation of the draft sensor is checked. The launch occurs according to the instructions.

Peculiarities

The characteristics of Junkers indicate that the device is ideally suited to Russian conditions. It is adapted to the pressure maintained in Russian gas pipelines and is equal to 13 millibars. In addition, the system is able to work with the low water pressure inherent in Russian water supply systems. For Junkers, 0.1 atmospheres is enough to perform the intended functions.

Such a gas burner is capable of heating from 11 to 16 liters of water per minute, which is considered a very high figure. In addition, the flame power automatically changes depending on the strength and size of the water flow. The structures are safe and can serve for a decent time. The devices are able to provide fast water heating and look great, which explains their popularity around the world.

Strict design, a variety of models differing in performance, design and ignition system, affordable price and simple controls are among their main advantages.

Operating rules

It should be remembered that some actions can lead to damage to the gas water heater. Junkers operation will be disrupted if fresh air is not provided. In addition, breakdowns will occur when using too long hoses, which lead to a decrease in pressure and the simultaneous opening of hot and cold taps. Naturally, the lack of periodic prevention will also lead to negative consequences.

It was already indicated above how you can turn on the Junkers column - this is done using a valve and a piezoelectric element that can light the wick. Once you light the burner, it will work throughout the day. Moreover, as soon as the hot water tap opens, the boiler will be connected automatically. You can change the gas pressure and water pressure by switching two control knobs.

If you decide to clean gas equipment, this is done according to a certain algorithm.

First, the gas and water are turned off, then the casing is removed.
At the next stage, the water unit and smoke receiver are dismantled.
Finally, the heat exchanger is removed at the end. The radiator can be washed in warm water, where a non-abrasive cleaning solution has been added. The brush should be long-haired and quite stiff.
The wick and main burner can be easily cleaned using a special awl. In addition, you will have to remove carbon deposits from each injector. However, it is not recommended to do this yourself. Better time invite a specialist per year who will combine inspection with descaling. The professional will also remove deposits, check the tightness of the fittings and clean the plates on the flue gas side.

If there is a smell of gas, it is prohibited to use electrical switches and telephones in the area where gas burner

It is important to immediately close gas tap, open the windows, ventilate the room and call the specialists who installed the equipment. To prevent dangerous situations, you should not store liquids or objects prone to ignition near Junkers

When the room temperature drops below zero degrees, the burner turns off and empties. If such a procedure was not carried out before the winter months, then when connecting the device the next season, you need to check whether the water is heated.

What to do if the gas water heater igniter goes out

The only one the right decision will call a licensed specialist from our service center for cleaning and adjusting the igniter. Checking the functions of the thermocouple and the gas control system. Gas smoking can also spread to the main burner, which will also need the attention of a technician. Usually, if the wick goes out during operation, then the work is adjusted by completely cleaning the gas water heater.

Device cost

The cost of the device depends entirely on the size (standard or mini) and its version (B, P, G). On average, the price for type B varies from 10 to 13 thousand rubles, for type P from 6.8 to 9.7 thousand rubles, for version G from 11 to 12 thousand rubles.

Each device comes with detailed instructions, which describes the technical components of the device, instructions for installation, configuration and care of it. The manufacturer recommends not to install the device yourself, but to trust specialists from the gas service. After all incorrect installation can not only break the device, but also cause significant harm to an incompetent installer.

The device has a large number positive feedback from satisfied customers. They consider it a reliable, safe and affordable device.

What to do if the geyser goes out for other reasons

In addition to the above problems, other problems may arise that negatively affect the performance of the column. You can also deal with them yourself.

To prevent the geyser from going rotten, there should be no drafts in the room

Other reasons for speaker fading:

The column does not light up if your water pressure is weak or the batteries are dead. New batteries and increasing the pressure will help solve the problem. It is also possible that your igniter is clogged, in which case it needs to be cleaned.
It is also possible that the membrane has exhausted its service life. In this case, it needs to be examined. Then clean or replace.
Maybe your module boards are burned out. To prevent this from happening, connect the speaker through a stabilizer.

If the speaker goes out when you release the button, then your neighbors’ satellite dish may be installed above the chimney. In this case, you need to reduce the flame or turn off the device and contact gas services.

Design and principle of operation

A typical column consists of a casing that is connected to the chimney through a pipe, a heat exchanger (the best is copper), a gas burner, an ignition system, sensors and a mechanism responsible for supplying gas. The gas water heater is connected quite simply.

Its operating principle can be examined on a model that has piezo ignition.

The slider is set to the middle position, after which you need to click on it. At this moment, the valve opens and gas enters the wick, also known as the igniter.
The piezoelectric element, located at the bottom left of the gas column, supplies a spark that ignites the gas. In this case, the slider button is kept pressed for up to 40 seconds. When it is released, the wick still continues to burn.
At this time, the column thermocouple is heated, which will then keep the electromagnetic gas valve open.

You can set the required water and gas consumption.

External signs of a geyser malfunction

If the junkers gas water heater does not light up, the reasons for this may be: external factors, not related to the condition of the main equipment.

Incorrect piping. In this case, it is necessary to check the connection of both the inlet and outlet pipes, which will also ensure an uninterrupted water supply.
No traction. This is usually caused by the chimney being clogged with a large amount of dust or foreign objects. Thus, combustion products are not removed and the burner goes out. In such a situation, you need to bring your hand to the chimney or a small flame (from a match or lighter). An important condition is the presence of an open window. If the draft level is sufficient, the flame will be deflected, and air movement will be felt on the palm.
Feels like bad smell gas in the room, which can be caused by neighbors installing an antenna above the chimney. In this case, you must immediately turn off the water heater, ventilate the room and call special gas services.
The column ignites, but after a while it fades out. This may be caused by excessive “sensitivity” of the protective relay. In such a situation, it is necessary to cool the room by opening the windows and contact service to replace the relay.
A discharged battery or battery may also cause the automatic ignition unit to not operate. This indicates the need to replace them, which you can do yourself.
Low water pressure may indicate a malfunction of the junkers geyser if the water pressures, for example, in the bathroom and in the kitchen, are different. If they are equally small, then the cause is a weak water supply network.
Extinguishing the wick can be caused by an oblique, uneven flame. As a result, poor heating of the thermocouple occurs, which automatically turns off the unit. IN in this case it is necessary to clean the dust, which is mandatory preventive measure when the wick goes out.

If you notice a problem with the pilot light (it smokes or goes out), your best option is to contact a licensed gas technician. He will check all the components that may give such a picture, and also clean your gas water heater.
If the column turns on and immediately goes out, do not try to turn on the device again, but cut off gas access to the problematic device and call a specialist. If the shutdown was caused by a gas leak, turning it on again may cause accumulation inside the room. carbon monoxide, which is unsafe for the health of people in the room.
Until the emergency service arrives, you can check the traction. To do this, light a match and bring it to the inspection hole on the column panel. If the flame is drawn inward, then the draft is sufficient. If there is no movement of the flame, you should disconnect the chimney pipe and repeat the manipulation with the match near the opening of the ventilation shaft. A lit match will also help you identify problems with the air flow into the room if you hold it near a window.

Features of column selection

The main difference between different models of geysers is the method of igniting them, whether it is a product from junkers, bosch, Neva or Lux. Today it is very rare to find a device that is lit with matches, so this option is not even considered.

The most popular speakers today are units with piezo ignition. In them, you just need to press a button located on the device panel. In addition, such units provide the ability to set the desired temperature of the supplied water.

Dispensers with electric ignition are the most expensive option, which allows you to significantly save gas. The device is turned on automatically by a flow of water. Purchasing such products allows you to save on energy costs and get heated water with maximum convenience, which justifies the high cost of the water heater.
Modern geysers, which are offered by well-known brands, as a rule, have three-level protection:

From the flame dying out.
Lack of draft in the pipe.
The occurrence of such a process as reverse thrust.

The equipment is protected from overheating by a hydraulic safety valve.

How to determine that there are internal faults in a gas water heater

The reasons why the water heater goes out may be the following:

filters are clogged;
the membrane is deformed.

If the quality of water supplied to the room is unsatisfactory (for example, hard, with a large amount of lime impurities), the metal filter grid becomes clogged. To restore the normal functioning of the unit, it is necessary to clean (replace) the mixer filter. Cleaning can be done with conventional detergents to remove rust and scale.

It is also important to clean the column itself from soot formations.

To examine the membrane, the bolts that secure the front panel of the speaker are unscrewed.

When inspecting the membrane, attention is paid to its shape (so that there are no deformations) and the presence of any chips. . If such defects are detected, it must be replaced.

And it is better to choose a silicone membrane, since its surface is more durable and elastic.

If such defects are detected, it must be replaced. And it is better to choose a silicone membrane, since its surface is more durable and elastic.

In this regard, the service life of this part will be longer.

To install the membrane, it is better to use the services of specialists, which will undoubtedly be safer. In addition, when you call a technician, you can simultaneously carry out general cleaning of the unit and conduct a full diagnostic of the device.

The reasons for the attenuation of the gas column may also be the following:

unequal pressures of hot and cold water, which can be solved by simply regulating the water supply;
lack of cold water before starting the unit, which, by the way, leads to rapid damage to the column;
insufficient time to hold the ignition button (20 seconds is the required duration);
There is a malfunction of the flue gas sensor, which can be determined by calling.

Now about malfunctions of Junkers speakers Junkers, Bosch Bosh

As I wrote above, the column is assembled on rubber O-rings. With old speakers they become woody and the seals begin to leak. It’s good if the master has them. You often come across different collective farm options from windings to sealants.
The membrane of the water block, unlike the membranes of Chinese speakers, lasts a very long time. I encountered a torn membrane once. The price of the original membrane is about 1800 rubles, the Chinese equivalent costs around 400 rubles. Who will find it? There is no point in the original, because the prices are astronomical.
The assembled geyser water block costs around 4500-5000 rubles. The price is high. For sale repair kits seals. You can sort out the water block yourself. Often the flow regulator leaks at the block. This can be treated by replacing the O-ring.
It is rare, but leakage of the water block rod seal occurs. Unfortunately, the oil seal cannot be replaced separately. Replaces with water block cover. The price of the cap with a rod is 2700 rubles. Very expensive!
On Junkers (Junkers) the traction sensor and overheating sensor are often tormented. Sometimes it’s so painful that I change the entire set of thermocouple and sensors. If changing the automation was not part of the plan, then you can painlessly short-circuit the temperature sensor (many imported gas water heaters do not have one at all). I don’t recommend short-circuiting the traction sensor, something that is clearly needed and has saved more than one life. It stops the gas supply to the column if there is no draft in the chimney. You can short-circuit it for a while, so as not to sit without hot water, and only in order to quickly find a replacement for it.

If you decide to buy such a speaker, then read the reviews on the useful website “Otzovik”. There, everyone described their column and gave ratings. My review is quite old. http://otzovik.com/review_1713020.html

Now I would give this column a solid B+. I recommend buying. Usually everything can be repaired without spare parts. Among the “cons” of the speaker, I would like to note the high price of spare parts. Luckily they don't break often.

Malfunctions requiring mandatory contact with a specialist

There are two main reasons why a geyser goes out:

one of three emergency sensors is triggered: traction, overheating or combustion;
the column is clogged, which makes it completely impossible to ignite it.

Initial actions in cases where the unit stops working:

To exclude the first option, you need to make sure there is no smell of gas, and draft in the chimney is carried out. If this is detected, you need to call a professional to clean the smoke valve.
The overheating sensor turns on if the heat exchanger is clogged or the control automation does not work. Its purpose is to protect the copper coil. In this situation, ventilate the room and wait until the unit cools down. Contacting a specialist is mandatory, since only a trained gas technician can properly regulate the column after descaling it.
If the third sensor is triggered, the gas supply is automatically shut off. In fact, this sensor is a regular thermocouple. If there is a flame, a current is generated and gas is passed through the solenoid valve. When the fire goes out, the valve shuts off the fuel supply for 10 seconds. In this case, you can hear a characteristic sound reminiscent of snapping fingers.

Important! If the gas water heater emits a gas odor when turned off, it is important to turn off all valves, ventilate the room and call gas services. .

Algorithm of actions when turning off the thermal mechanism:

stand for 10-15 minutes (to cool the sensors);
chimney draft is checked;
the presence of gas is checked;
the room is ventilated;
an attempt is made to start the unit (put the power knob in the position required to turn it on, keep it on for 20 seconds, press the “piezo igniter” button);
if the actions taken did not lead to desired result, the functioning of the combustion sensor is checked;
the non-working state of the combustion sensor can be caused by contamination of the pipe, which operates on the principle of a vacuum cleaner, so it should be thoroughly cleaned;

To clean the device that supplies combustion gas (pipe), the following actions are carried out:

the handle that regulates the water temperature is removed;
the required ignition position is set;
the surface of the gas device is removed;
use a screwdriver to lift up the pipe clamps located on top;
These clamps are placed separately;
by moving the lower clamp, the pipe is removed;
the tube on which dust is collected is washed under running water, cleaned with cotton swabs and sticks;
A prerequisite for normal pipe cleaning is the removal of all residues detergent and water;
the nozzle also undergoes thorough cleaning;
the tube is installed back into the device, starting from the top mount, where the springy end is located;
for the lower fastening, you will need to apply enough force to secure the pipe tightly;
the clamps are put back in their original place;
a second attempt is made to ignite the column by simultaneous switching on piezo ignition and power regulator;
handles and buttons are held in this position for at least 10 seconds;
The temperature control knob is inserted into its original place.

In addition, the most common reason for the damping of a geyser is described in this video:
