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 the 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. Latest models 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 rinse the part under running water, you can use a brush.
• Burner blockage in a 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 fault. 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.

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 continuous 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 is 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 the trademark belongs to such a well-known company as 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 without visible reasons, which I was never 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 about modern speakers, you can’t help but be amazed at how bad the quality has become. 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.
