Common breakdowns
Often the device breaks down due to its improper operation. It happens that this happens due to corrosion, poor water quality and power surges. If after the acquisition a marriage was discovered, then it is eliminated free of charge at the service center.
Paid repairs will cost approximately 1500 r. The price depends on the complexity of the damage. It is recommended to take the device to the service yourself in order to save on delivery or calling a private master. The most common faults are:
- water leak;
- overheat;
- the occurrence of loud sounds emanating from the device;
- water does not heat up;
- 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 repair, make sure that all fixtures of the device are correctly fixed, and during its operation there will be no gas leakage. It is only allowed to repair the device yourself if you have such experience. Only original spare parts purchased from Bosch should be used.
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 is completed with a detailed instruction, which describes the technical component of the device, instructions for installing, configuring and caring for it. The manufacturer recommends that you do not install the device yourself, but trust the specialists from the gas service. After all, improper installation can not only break the device, but also cause significant harm to an inept installer.
So it's time to write an article not about computers and 1Ski, but about repairing a Bosch / Junkers WR13 gas column. Who would have thought that an IT specialist would get there. As it is customary, it is better not to disassemble such things in the department of gas companies and without special knowledge. In fact, there is nothing wrong with it, and with more or less straight hands, it is possible to do it yourself. Moreover, there is a crisis in the country and I want to save money. It all started with the fact that the column stopped going out when the hot water was turned off, I had to run and turn off the gas manually. Google suggested that two main blocks are responsible for this: hydraulic fittings (water unit) and gas fittings. They are connected together in such a way that when water is supplied, the water unit, using a membrane pressing on the pin, presses the gas valve, thereby opening the gas supply. When the water is turned off, the gas valve closes. In general, the problem is somewhere here! (number 14 in the picture)
So, let's get started ... Here he is our patient:
All we need is 2 screwdrivers (Phillips and flat) and a wrench to unscrew the nut securing the water pipe. For safety, we will shut off the water and gas supply to the apartment. Remove the protective cover by unscrewing the two screws from the bottom:
We get access to the insides: We take out the bracket that fixes the water supply pipe to the heat exchanger:
We take out the pipe itself:
We unscrew the two screws securing the water unit to the gas valve:
And then a picture with oxides at the attachment point opened up to me. The mechanism was broken, and water seeped in there. The metal oxidized and the gas valve began to jam (it stopped returning to its original position). That's the reason for not turning off the gas supply! Let's try to clean everything as much as possible and develop the valve itself:
It should be pressed inward and returned to its original position. Now let's analyze the water block itself:
We take out the bracket and take out the flow regulator (sleeve with a spring):
We unscrew the bolts and remove the cover of the water unit:
Under it we see a worn membrane:
And the lid itself fell apart from time to time (the column is currently 7 years old):
As it turned out, spare parts for gas water heaters are not so easy to find. And the prices for them, frankly, horse. At the price of a new Bosch Junkers GWH 13 P (WR13-2 P2) column - 10,000 rubles. I found the cheapest membrane in the city (code 8700503083) for 1400 rubles. and a cover for water fittings WR10, 11, 13, 15 (code 8705500105) for 2400 rubles. Total 3600 rubles. More than a third of the column. So before proceeding with the repair, think about whether it is necessary. But it was too late ... the column was dismantled and I didn’t want to install a new one, so I decided to continue what I started! (although I almost freaked out and did not go for a new Chinese one for the same money) The picture shows old and new parts. The difference is immediately visible:
Now we install a new membrane and a water fitting cover, assembling everything in the reverse order:
Service center for the repair of gas water heaters LLC TeploSpetsTsentr 7 495 774-95-70
Today it is impossible to imagine a city apartment without a geyser. - this is the most affordable and reliable equipment for heating cold water. The column simultaneously supplies hot water to several points of water intake - to the faucet in the kitchen, to the faucet and bathroom shower. The breakdown of the unit entails a lot of domestic inconvenience.
No matter how old they are, speakers from even the most reputable brands sometimes fail. Insufficient water heating rate, yellow or green flame in the burner, loud hum during operation, black soot flakes are typical consequences of non-periodic or unskilled maintenance of the units.
Breakdowns and methods of repairing speakers
The main reason for the breakdown of a gas instantaneous water heater is mechanical or natural wear of the working elements of the device. Mechanical wear includes cracking of the membrane gasket, failure of the solenoid valve, and burning of the thermocouple. The natural wear of the components is clogging of the water purification filter, contamination of the heat exchange unit, clogging of the ignition tubes and burner nozzles.
Wick fading after depressing the gas supply button
This is the most common device failure. The cause of the failure is the clogging of the igniter channel or the failure of the bimetallic sensor.
To fix the problem, you should call the master of the service center. The master will clean the column, thereby extending the life and warranty of the water heater.
The column does not heat up the water fast enough
It happens that the column does not heat running water fast enough, and when cold weather sets in, it does not work at all. Check the integrity and flexibility of the membrane gasket. In case of cracking or loss of flexibility, replace the membrane with a new element. If the membrane structure is intact, clean the gasket surface and replace the element.
In order for the column to work without failures, carry out preventive maintenance of the unit once or twice a year. For this, it is recommended to contact our company. The first maintenance is carried out before the onset of winter cold, the second one in the spring, after the heating season.
Speaker locks up after a few minutes of operation
Check the air draft in the chimney. To do this, attach a sheet of paper to the chimney. The sheet of paper must be held on the wall by the flow of outgoing air. The second way to check the thrust is a burning match. Hold a burning match up to the chimney and observe the flame. If the flame rushes to the chimney, the draft is normal; if it deviates from the channel, the draft is broken.
To restore air draft, clean the chimney from soot, dust, and small debris. To carry out a complete audit of the gas exhaust system, contact specialized companies. Trained engineers will conduct a comprehensive check of the system using special equipment.
Repair of geysers at the customer's address
Regulatory requirements prohibit the dismantling of gas instantaneous water heaters that are connected to the main gas pipeline. According to the rules of the gas supervisory service, the user must call an engineer at home to carry out service work.
To carry out scheduled maintenance or repair of a geyser, a current or comprehensive audit of the exhaust gas system, please contact our company. We will send trained commissioning engineers who will check the technical condition of the chimney and the unit, identify possible malfunctions in the operation of the equipment and eliminate breakdowns.
Geysers are designed to heat water in an apartment and a house in which there is no hot water supply. They have recently become popular heating appliances among the population, both private houses and residential apartments. They are often bought by families with children, as in our time there are more and more interruptions in the supply of hot water.
The most popular models of gas water heaters are easy to operate, they are safe and quickly allow you to adjust the degree of heating of water in the house. In this article, we will analyze how the Junkers gas column works and how it is repaired..
Open type how to start a geyser
Flowing geysers installed in residential premises cause a lot of controversy. It should be noted that modern gas water heaters are not dangerous if you follow all the rules for their use. The rules for handling the column should be known to everyone who lives in an apartment or house and uses such a column to heat water.
If there is a large accumulation of gas in the room, it is necessary to open the windows to reduce the concentration of gas
It is important to know that in the presence of gas in the room it is strictly forbidden to turn on electrical appliances and fire. If the column is malfunctioning, you should call the gas service
How to kindle an open type column:
It is strictly forbidden to kindle a column if there is no reverse draft in the chimney.
Do not turn on the device without understanding the instructions.
It is important that the room is equipped with a constant supply of air.
You can not independently repair or make changes to the operation of the gas column.
When kindling, do not touch the front of the panel. When you turn on the column, it is better to set it to low power. It should be noted that modern models of columns are equipped with safety devices that stop the operation of the column if there is no traction.
Advantages and disadvantages
The device has both advantages and disadvantages. The benefits include the following characteristics:
- equipped with flame modulation;
- increased security;
- adaptability for use in Russia;
- beautiful appearance.
Thanks to its design, Junkers will fit perfectly into any interior. The device operates at a gas pressure of 13 Mbar. Such pressure is present in all gas pipelines in Russian homes. If we compare it with the European pressure (20 Mbar), then it is much lower, which creates problems when buying other gas water heaters. The device functions effectively in a multi-storey building, where the pressure in the water supply system is very low (it works from 0.1 ATM.)
Junkers has increased safety and low cost in comparison with its counterparts. When the water pressure changes, the device will automatically select the power at which the water heating will be optimal. The device is assembled by German designers and has a 2-year warranty. With proper installation and operation, the device can last more than 13 years.
Among the shortcomings are
the fact that in most modifications of Junkers geysers there is an increased noise level. During the operation of the device, problems with the heat exchanger and leaks in the seals appear, which creates a risk of spoiling the flooring under the gas water heater or completely flooding the neighbors.

The goal of this article is to teach us how speakers work. But articles are different. Moreover, it is not clear where they came from. Hence the Question: Why can the article be trusted?
In fact, in order to choose a geyser, due to the lack of information necessary for making a decision, we all start doing the same Internet idiotic thing, looking for reviews about geysers. The reviews we come across are quite varied, but somehow very, very subjective. Sometimes they are just funny and written at the kindergarten level, like "Don't hang out with Natasha, she bites." In general, we decided to take a chance and leave our reviews here. It is clear that the reviews of the sellers of spare parts can be heavily infected with the interests of any speaker seller. What is the best column? Of course, which I sell - and there is no doubt about it. But we have found one option, where only one basis will be laid for achieving our mutual trust. - knowledge
. Nothing else. Knowledge on this issue is purely technical.
. Now we will look inside the column and try to prove to you that we really know what we are talking about. And at this moment you will just be there. The other way is simply false. Therefore, this article is a kind of result of research. For today, there may be the only and best objective version for consultation in our store. Although, it is very possible that in six months we will gain additional knowledge and will tell a little differently. Knowing the current technical level of the average buyer, we consider it our duty to warn that the article is uninteresting and heavy.
Replacement of nozzles for gas stoves for bottled gas "Hephaestus". Instruction.
In order to bring us as close as possible to the feelings of an installer who replaces jets for bottled gas on a gas stove, we chose the Brest 300 gas stove, which has been in use for many years. Yes, and in practical life, quite often, mostly old ones are converted to liquefied gas gas stoves, which are taken to the country or to country houses. When replacing jets, we are waiting for several important discoveries
, which we can only begin to talk about when we visually begin to approach the intended goal. This will help a number of necessary photos that had to be taken in order to fully illuminate the implementation of the task.
The Junkers geyser installed in the house will provide quick preparation of hot water and will please with its excellent appearance. This is a modern water heating equipment manufactured on the basis of advanced technologies. However, the use of advanced developments did not deprive Junkers gas water heaters of certain shortcomings. However, they are found in many houses and apartments. Here are the main advantages of these columns:
- Excellent appearance - Junkers speakers have an excellent strict design;
- Large selection of performance;
- Convenient control - a minimum of control elements.
The choice of buyers is provided with a large selection of columns that differ in their performance, thermal power and type of ignition system. Unfortunately, there are no design solutions. Their main advantage is their affordable price. Flow-through geysers from this manufacturer are offered in many stores selling water heating equipment and gas equipment. What do reviews of Junkers gas water heaters say? Our review will tell about this.
Junkers geysers have received many positive and negative reviews. After reviewing them, you can make the right choice and choose the most reliable gas water heater.
Gas burner Junkers miniMAXX WR 13G
In general, a good column, it served me for three years, after which the heat exchanger began to leak. Disassembly showed that a crack had formed in it.This was the most serious malfunction, and for three it served properly. As it turned out, a flimsy heat exchanger is a disease of all gas water heaters from this manufacturer. The fact is rather strange, considering that the trademark belongs to such a well-known company as Bosch. The verdict is this - if you're lucky with the heat exchanger, then the geyser will last a long time. If you are not lucky, you will have to constantly solder the heat exchanger.
Advantages:
- The absence of batteries allows you to get rid of unnecessary expenses, since ignition is carried out from a miniature generator rotating under the pressure of water;
- Solid appearance, no frills;
- Productivity up to 13 l / min, this is enough for a washstand and a shower cabin.
Flaws:
- Flimsy heat exchanger, leaks regularly and requires soldering. Moreover, soldering helps for a short time;
- Sometimes it goes out for no apparent reason, which I could not find.
Geyser Junkers miniMAXX WR 10P
If the burner does not ignite at the Junkers gas column, it's time to clean the igniter. I came to this conclusion after a year of fiddling with the miniMAXX WR 10P column. The device is not bad, but not without some shortcomings - and the burner is an eloquent proof of this. I bought this speaker for reasons of economy, so I took a model with a minimum power, since I live alone, and usually either the faucet or the shower works for me. The column quickly heats the water, ignites without pops and rumbles. I was pleased with the presence of protection against overheating and a gas control system - this makes the column safer.
Advantages:
- Fast heating of water, no need to wait long for it to warm up;
- A minimum of controls, there are no unnecessary things, such as self-diagnostic systems;
- Extremely simple design, you can repair the device yourself, without calling the master;
- No need to spend on batteries.
Flaws:
- Often there are problems with the operation of the igniter, but the burner itself almost never goes out;
- The manufacturer promised a trouble-free start at a minimum pressure, but I would not say that it always starts - in the summer it starts with two or three attempts when the water barely flows.
An easy way to ignite how to turn on a Bosch gas water heater
The use of modern gas water heaters usually does not cause difficulties
When buying speakers, you should pay attention to the presence of a passport and a guarantee for the goods.
It is also very important that, along with the column, the seller issues instructions for its operation.
How to fire up a Bosch speaker:
Move the knob to the right if it is in the off position.
The regulator should move to the "Piezo ignition" position. This means that the spark icon and the vertical buttons will connect.
The start button should be “drowned” with your finger, while pressing the piezo power button
The characteristic clicks will notify that the piezoelectric element has worked.
It is important to ensure that the flame does not go out for the first ten seconds. Then you can translate the power to the desired level.
After the power is transferred to the desired one, the flame constantly burns in the mode that was set. But when hot water is turned on, the column starts automatic heating of water. Turning off the column is simple - you need to move the slider all the way.
How to ignite by type of ignition
Manual ignition
This method is already outdated and is rarely used in modern speakers. Such devices are poorly protected both from water pressure drops and from fire attenuation.
Installing such devices at home is not recommended now.
How to light a column with manual ignition:
- Turn off the valve on the tap that supplies water to the column.
- Light the fuse with a match or lighter.
- Open the valve on the valve supplying gas to the column.
- Sometimes it takes a little time to ignite the burner until air is expelled from the burner duct. To speed up the process, first open and then close the hot water tap several times.
Piezo ignition
This option for igniting the column is more modern and common.It is very easy to use, but it has such a disadvantage as increased gas consumption. While the column is not working, the wick is still smoldering inside it, so the gas, although in small quantities, is burned constantly.
How to light a column with piezo ignition:
- To start, you need to press a button that acts on the piezoelectric element. This will provide a spark to ignite the pilot burner wick.
- Open the valve supplying gas to the apparatus.
This is clearly shown in the video below.
Automatic ignition
This is the most modern and profitable option for igniting gas water heaters. It is also called electric because it is based on the transmission of an electric spark. Its appearance is provided either by batteries or a hydraulic turbine. Combustion will be controlled by different sensors, and as soon as the user closes the hot water tap, the ignition wick will go out.
How to light a column with electric ignition:
- Make sure that gas and cold water are supplied to the column.
- Open a hot water tap.
See a small preview.
The Junkers company existed until 1932. From that moment on, the company was bought out by Bosch Gruppe, which, however, did not affect the name of the water heaters produced by the division of the main office.
Flow-through geysers Junkers (Junkers) are available in several modifications that differ in the principle of ignition, as well as the type of combustion chamber. Flow-through boilers operating using an ignition burner are popular among domestic consumers. The average service life of the Junkers column exceeds 15 years.
Geyser Junkers miniMAXX WR 15P
Behind the strict appearance and good performance lies a poor filling, not much different from the filling of domestic gas water heaters Oasis. Let's start with the heat exchanger - it is unrealistically thin, lost weight six months after buying the column. Then the gaskets began to leak, they had to be constantly changed, otherwise it was possible to flood the neighbors. Sometimes the igniter goes out, as the gas control is triggered - and it is impossible to understand why it suddenly works. It is impossible to repair its “guts”, since everything is very thin, flimsy, non-repairable, I don’t know at all how it was developed and how it is produced - this is one big drawback. And even the fact that she can work with little pressure does not justify her snotty fragility. This is not a column, this is sheer torment.
Advantages:
- Easy control, no extra handles and buttons, the temperature is easily regulated;
- Good performance, you can open two taps at once or take a shower while someone is washing the dishes;
- Noise is not strong, does not scare anyone with its noise.
Flaws:
- This column itself is one big drawback, since literally everything breaks in it;
- Terrible heat exchanger, the thinnest copper that can not withstand heat;
- Constantly flowing, threatening to flood the neighbors. Who knows how it will break through next time;
- It cannot be repaired, since it is impossible to repair these "snots".
Junkers speaker device
-
semi-automatic
The company began producing speakers back in 1968. During operation, an ignition burner is used. Ignition is carried out using a piezoelectric element. The main burner is switched on when the DHW tap is opened. - Automatic
— work from batteries or the hydrogenerator. The series includes simple Junkers geysers with an open combustion chamber, as well as multifunctional models with modulated power. The performance of the burner device varies depending on the water pressure.
In the internal structure of Junkers gas flow columns, only high-quality materials are used. All water heaters undergo mandatory testing and are subject to certification.
