Junkers gas flow heater. Do-it-yourself repair of Junkers speakers, typical faults: goes out, goes out, doesn’t light up. Malfunctions requiring mandatory contact with a specialist

Gas water heaters installed in many apartments and private houses. They allow you to forget about problems with water supply shutdowns and repairs. On the other hand, they also have flaws and are prone to breakdowns. How to repair Junkers speakers yourself? In the article we examined the main methods.

Typical malfunctions of the Junkers geyser

The Junkers heater is more often subject to problems related to ignition systems. Users complain that over time the wick or burner goes out, the device does not light, and the water does not heat well.

To determine the cause of the breakdown, you need to inspect the parts and check their functionality. We will give examples of common Junkers problems and how to fix them.

The equipment does not turn on, does not light up

Why is this happening? The reasons may be hidden in external factors:

• Incorrect water connection. Check the condition of pipes and connections. Open the instructions - make sure that the connections are made correctly and that water flows normally into the system. Otherwise, the pressure in the line will be weak and will not allow the gas valve to open.
• No traction. The latest models are equipped with protective sensors. The principle of operation of the draft sensor is to detect its presence. If there is no traction, the sensor sends a signal to the module - the column turns off. The main reason is a clogged chimney. Combustion products are not discharged normally and the burner goes out. There may be poor ventilation in the room. The chimney needs to be cleaned or a vent valve installed.

To check the draft, hold a burning match to the control window. The flame deviates - there is draft, it burns evenly - no.

• A similar situation arises when the chimney outlet is blocked. Look, maybe some object or a satellite dish on the roof is preventing the release of combustion products.
• Overheat. Scale deposits reduce the efficiency of heat transfer, which can cause the column to overheat. Then the sensor is triggered and it turns off. Once a year, it is recommended to clean the heat exchanger from scale, as well as install cleaning filters. , read the previous article.

• Sensitive relay. You can observe that the burner ignites, then the pilot goes out. Try lowering the room temperature by opening the windows, or replacing the relay.
• . Equipment with electronic ignition receives a spark from batteries. If the batteries are discharged, you need to install new ones.

• Insufficient water pressure. Experts recommend selecting a column in accordance with the parameters of your system. If the device is too powerful and requires high pressure, you will have to install a pump or install a new one.
• Abundance of dust. If you have not cleaned the parts from dust, the flame in the burner may be mowed and not warm up the thermocouple. Cleaning is carried out with a brush or vacuum cleaner.

The wick goes out. Internal problems

What to do if the equipment stops working? Understand the causes of the problem.

• Defective rubber membrane. Why is it needed? When you open the mixer, pressure arises in the line, which acts on the membrane. Bending, she pushes out the rod, and it opens the gas valve. If the membrane is damaged or stretched, the system malfunctions. Replace element. More details about the repair are written in the article “ ».

• The filter mesh is clogged. It is located at the entrance to the water node. It becomes clogged with small debris, pieces of scale, and rust. Remove and wash the part under running water, you can use a brush.
• Burner clogged gas boiler . During the combustion process, soot and soot are deposited on the walls. If they are not removed in time, they clog the burner holes. Clean.
• Microswitch failure. IN in good condition When igniting, a click is heard - the switch is activated. If you do not hear any sounds, then check and change the element.

• Water fittings do not work. It is necessary to clean the parts from rust and lubricate them.
• Wiring violation. Inspect the entire wiring harness and replace damaged parts.
• Broken contacts. The contact groups are tightened and cleaned.

Other causes of similar problems:

• The gas supply valve is closed.
• The piezo ignition does not work, or the pressing time is short (you need to hold it for 10-20 seconds).
• Mixing of flows when the cold tap is open more than the hot one. The pressure decreases and the wick goes out.

• The gas sensor has failed. Need a replacement.

What factors cause equipment failure:

• Poor ventilation. There is not enough oxygen to keep the flame burning. Check the ventilation for blockages. If you have plastic windows, installing a valve for ventilation will help.

• Mixing flows.
• Late equipment maintenance.
• When connecting, long hoses are used, which reduces pressure.

When to call a professional

If you notice such problems, it is better to contact the service. But before that you need to make sure that it is broken:

• The draft, overheating and flame sensors are constantly triggered.
• The column is clogged.

Often the pipe responsible for the gas supply becomes clogged. How to clean it:

• Remove the temperature control knob.
• Remove the cover of the device.
• There are clamps on top of the pipe. Unfasten them.
• Remove the pipe, clean it, and wash it under the tap.
• Dry and reinstall the part.
• Test the operation of the equipment. While holding down the power control, press the piezo ignition button. Hold for 10 seconds.

If all else fails, it is better to contact a technician to replace the sensors. Many reasons for the damping of the Junkers heater can be eliminated with your own hands. If you connect the device correctly and keep it clean and in good working order, such problems will not arise.

A Junkers geyser installed in the house will provide quick preparation hot water and will delight you with its excellent appearance. This is modern water heating equipment manufactured using advanced technologies. However, the use of advanced developments did not deprive Junkers geysers of certain disadvantages. However, they are found in many houses and apartments. Here are the main advantages of these speakers:

• Excellent appearance– Junkers speakers have an excellent, strict design;
• Wide range of performance options;
• Convenient control – a minimum of control elements.

Customers can choose from big choice columns that differ in their performance, thermal power and type of ignition system. Some design solutions, unfortunately, is missing. Their main advantage is affordable price. Flow-through geysers from this manufacturer are offered in many stores selling water heating equipment and gas equipment. What do reviews say about Junkers geysers? Our review will tell you about this.

Junkers geysers have received many positive and negative reviews. After familiarizing yourself with them, you can do right choice and choose the most reliable gas water heater.

Geyser Junkers WR 13P

Gennady

We bought a Junkers WR 13P gas water heater less than a year ago and are already planning to replace it. By its design, the column resembles a leaky sieve - water flows from all the holes, and the heat exchanger has already been soldered a couple of times. There is a feeling that the heat exchanger itself is made of thin foil and is completely unsuitable for working in gas equipment. Not a week goes by that I don't have to tighten or patch something, it just drives me nuts. Seals are constantly leaking, and gas reducer It broke down after just a couple of months of use. If you want to keep your nerves strong, do not buy this water heater; it is better to buy a Bosch gas water heater.

Advantages:

• Electric ignition, thanks to which the column is freed from a constantly burning igniter;
• Works well at reduced pressure, gas is ignited confidently and without hesitation;
• Maximum capacity 13 l/min, which is what is needed for two taps.

Flaws:

• Everything that can leak leaks, from the seals to the heat exchanger;
• It makes noise during operation like an old Soviet speaker.

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 incredibly thin, it leaked six months after purchasing the column. Then the gaskets began to leak, they had to be constantly changed, otherwise the neighbors could be flooded. Sometimes the igniter goes out because the gas control is triggered - and it is impossible to understand why it suddenly triggers. It is impossible to repair its “guts”, since everything is very thin, flimsy, and cannot be repaired, I don’t even know how it was developed and how it is produced - this is one a total flaw. And even the fact that it can work with low pressure does not justify its snotty fragility. This is not a column, this is complete torture.

Advantages:

• Easy control, no extra knobs and buttons, temperature can be easily adjusted;
• Good performance, you can open two taps at once or take a shower while someone else is washing the dishes;
• It doesn't make much noise and doesn't scare anyone with its noise.

Flaws:

• This column itself has one big drawback, since literally everything in it breaks;
• Terrible heat exchanger, thin copper that cannot withstand heat;
• It constantly flows, threatening to flood the neighbors. Who knows how she will break through next time;
• It cannot be repaired, since it is impossible to repair these “snots”.

Gas burner Junkers miniMAXX WR 13G

Overall, it’s a good column; it served me for three years, after which its heat exchanger began to leak. Disassembly showed that a crack had formed in it. This was the most serious malfunction, and for three years it worked properly. As it turned out, a flimsy heat exchanger is a disease of all geysers from this manufacturer. The fact is quite strange, considering that trademark belongs to such famous company, like Bosch. The verdict is this - if you are lucky with the heat exchanger, the geyser will last a long time. If you are unlucky, 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 water pressure;
• Solid appearance, no frills;
• Capacity up to 13 l/min, this is enough for a washbasin and shower.

Flaws:

• The heat exchanger is flimsy, leaks regularly and requires soldering. Moreover, soldering does not help for long;
• Sometimes it goes out for no apparent reason, which I have never been able to find.

Geyser Junkers miniMAXX WR 10P

If the burner at the Junkers gas water heater does not light, it’s time to clean the igniter. I came to this conclusion after a year of fiddling with the miniMAXX WR 10P speaker. The device is not bad, but it is not without some shortcomings - and the burner is eloquent proof of this. I bought this speaker for reasons of economy, so I took the model with the minimum power, since I live alone, and usually either the faucet or the shower works for me. The column quickly heats the water and ignites without popping or roaring. I was pleased with the presence of overheating protection and a gas control system - this makes the speaker safer.

Advantages:

• Quick heating of water, no need to wait long for it to warm up;
• There are a minimum of controls, there are no unnecessary things, such as self-diagnosis systems;
• Extremely simple design, you can repair the device yourself, without calling a technician;
• No need to spend money on batteries.

Flaws:

• There are often problems with the operation of the igniter, but the burner itself almost never goes out;
• The manufacturer promised trouble-free starting with minimal pressure, but I would not say that it always starts - in the summer it starts after two or three attempts, when the water is barely flowing.

Geyser Junkers Jetatherm WR 275-1KDP

We bought this speaker a long time ago. Reading reviews of modern speakers, you can’t help but be amazed at how poor the quality is. But our column has been in service for 7 or 8 years already. During this time, practically nothing broke in it, I only changed the current gaskets a couple of times. But otherwise the model deserves positive feedback– it is reliable and works well in low pressure conditions. Quietly heats water up to 55-60 degrees, this is more than enough for the home. True, I would gladly supplement it with a battery-powered ignition - and then it would not be worth it.

Now the time has come to write an article not about computers and 1Ski, but about gas repair Bosch speakers/Junkers WR13.
Who would have thought that an IT specialist would climb there. It’s a tradition that such things are best left unchecked in the departments of gas companies and without special knowledge. In fact, there is nothing terrible there, and with more or less straight hands, you can do it yourself. Moreover, there is a crisis in the country and you want to save money.
It all started when the heater stopped going off when the hot water was turned off, so I had to run and turn off the gas manually.
Googling 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 on 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 is our patient:

All we need is 2 screwdrivers (Phillips and flathead) and a wrench to unscrew the nut securing the water pipe.
For safety, we will cut off the water and gas supply to the apartment.
Filming protective cover by unscrewing the two screws from below:


We get access to the internals:

We remove the bracket securing the water supply pipe to the heat exchanger:


We take out the pipe itself:


Unscrew the two screws securing the water unit to the gas fittings:

And then I saw a picture of oxides at the attachment point. The mechanism was blown apart and water leaked out. The metal oxidized and began to jam the gas valve (it stopped returning to its original position). This is the reason for not turning off the gas supply!
Let's try to clean everything up as much as possible and develop the valve itself:

It should press inward and return to its original position.
Now let's look at the water block itself:


We take out the bracket and take out the flow regulator (sleeve with a spring):


Unscrew the bolts and remove the water unit cover:

Underneath we see a worn membrane:

And the lid itself has fallen apart over time (column on this moment 7 years):


As it turned out, spare parts for gas water heaters are not so easy to find. And the prices for them, frankly speaking, are outrageous. With the price of a new Bosch Junkers GWH 13 P (WR13-2 P2) speaker – 10,000 rubles. I found the cheapest membrane in the city (code 8700503083) for 1,400 rubles. and water fitting cover WR10, 11, 13, 15 (code 8705500105) for RUB 2,400. Total 3600 rub. More expensive than a third of the column. So before you start repairing, think about whether it is necessary. But it was already too late... the column was disassembled and I didn’t want to install a new one, so I decided to continue what I started! (although I almost freaked out and didn’t 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 water valve cover, assembling everything in the reverse order:

Hooray. Everything worked out for me. Now the flame lights up and goes out as it should!
What do you want to say in the end?! When I was puzzled by the choice of column 7 years ago, Junkers were praised as the most reliable and repairable. I find it difficult to say whether 7 years is a lot or a little for reliability, although the old Soviet ones still work for people and at least they care! But at such prices for spare parts, this maintainability is not needed. Now I would choose the cheapest Neva or Chinese Oasis for 4-5 thousand rubles and if it breaks, I would simply throw it away without worrying and install a new one for the price of repairing this Junkers/Bosch. One hope is that this prevention will allow the column to work for at least as long...
And finally, for those who don’t understand the pictures, I’ll give you a link to a disassembly video gas burners Bosch/Junkers from the company Teplotekhnika St. Petersburg: http://www.youtube.com/watch?v=a2aIn93fyQ8

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 and are 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 adjusted based on the flow in the water supply 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

Each device includes an instruction manual, which provides detailed information on 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 in this list, since they can be eliminated free of charge by sending the equipment to 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:

1. 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.
2. 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.
3. The device began to make loud noises and overheat. The reasons are completely similar to the previous paragraph.
4. 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 official representative Bosch company. For example, a new hydraulic fitting will cost up to 7,500 rubles, an igniter - 400-500, an electronic ignition device will cost 5,500 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 technicians 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. The Russians are quite happy service life water heaters equal to 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 adapted to pressure in domestic gas pipeline system 13 mbar, when in Europe the indicator reaches 20;
• water heaters are able to function in combination with plumbing 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 of 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.
