Repairs and malfunctions of various dishwashers
Even a non-specialist understands that a dishwasher of any brand can theoretically experience any breakdown. If you start listing this so-called list of typical breakdowns, and even talk about how to fix them, you could write a whole book. When writing this article, we decided to take a different approach.
Leading service centers in the world keep statistics on dishwasher malfunctions. We decided to describe the most common malfunctions found in specific brands of dishwashers, based on these statistics, not forgetting to touch upon the repair of professional dishwashers, and this is what came out of it.
Specific breakdowns of Hansa machines
According to statistics from leading service centers, the main problem with Hansa dishwashers is the water level sensor. It’s difficult to say why this particular sensor breaks down more often in cars of this brand; maybe the design of the car or low-quality parts is to blame, but the fact remains a fact. In most cases, the pressure switch burns out, so it cannot be repaired; it needs to be replaced.
How to find out that it is the pressure switch of the Hansa dishwasher that has failed? What are the symptoms of the problem?
- Water constantly fills and drains into the dishwasher.
- The amount of water in the dishwasher tank is less than permissible.
- More water is poured into the dishwasher tank than allowed.
- The dishwasher suddenly stops working and stands still without pumping out water.
How to repair Hansa dishwashers in this case? You need to check the pressure switch yourself and then, depending on the result, replace it with a new one.How to do this is described in sufficient detail in the article. Replacing the pressure switch in a dishwasher. This publication tells not only how to repair Hansa dishwashers, aimed at replacing the water level sensor, but also how to properly check this element.
For your information! Hansa dishwashers are assembled mainly in China, but surprisingly their quality is far from the worst.
Specific breakdowns of AEG machines
Experts say that the most common breakdowns of various models of AEG dishwashers are malfunctions of the drain pump. In general, the situation is quite surprising, given the truly German quality of this part and the impeccable installation, but, as they say, the statistics are inexorable. How can you tell if the pump is broken? In fact, this cannot be done 100% based on external symptoms, although some of their manifestations need to be taken into account.
- The pump makes uneven sounds of varying strength, while dirty water continues to stand in the washing chamber.
- At the moment when the washing program should drain dirty water, the dishwasher freezes and stops working.
- After starting the washing program, the dishwasher freezes and displays error I 20.
If one of the above signs of breakdown makes itself felt, this is a reason to check the pump with a multimeter. How to check and repair AEG dishwashers? Let's do the following.
- Unplug the dishwasher, turn off the water and disconnect the inlet and drain hoses.
- We take the dishwasher out to a free place, after placing a rag there.
- We take out the car and put it on the back wall.
Important! When you tilt the dishwasher, some water will spill out onto the floor.
- Carefully remove the pan, find the pump (a pipe with a drain hose is connected to it) and connect the multimeter probes to the contacts. Based on the results of the inspection, we decide to change the pump or look further for the cause of the malfunction.
You can replace the pump on an AEG dishwasher yourself; read the article on how best to do this. How to replace a dishwasher pump, although of course it is better to entrust this work to a specialist, because a dishwasher is expensive, you never know.
Specific breakdowns of NEFF machines
A specific breakdown of Neff brand dishwashers is the frequent operation of the leakage protection system. Users who encounter this problem for the first time are very worried and quickly run to call the technician, the technician arrives in 30 seconds. eliminates the cause of the problem, gets the money and leaves. We don’t think this is very fair, so we will now tell you how to repair Neff dishwashers in a couple of minutes with your own hands, and most importantly, absolutely free.
First, let's figure out how and why the leakage protection system of these machines works. The fact is that at the bottom of the washing chamber of the Neff dishwasher there is a rather large float, or rather the upper part of the float mechanism of the leakage protection system. When water enters the pan, the float rises, the sensor is triggered and the machine stops operating. This happens under normal conditions.
Unfortunately, most often it happens differently. Residues of food and dirt get under the movable cover of the float mechanism, which causes it to rise and trigger the protection. Of course, in this case there is no water in the pan and it is useless to look for it there. What need to do?
- Unplug the dishwasher from the on/off button.
- Open the washing chamber door.
- Place your hands on the float cover of the leakage protection system (the float is located next to the debris filter).
- Raise and lower the float several times; you can immediately use a cotton swab to carefully remove the dirt that has accumulated under it.
- Next, turn on the machine and check how it works.
Believe it or not, this is where the repair of Neff dishwashers can end, unless of course we are talking about this most common malfunction.
Note! Often, foreign objects (a chicken bone, a piece of a broken plate, etc.) get stuck in the hole under the top of the float, preventing it from working properly. If the foreign object is not removed, the protection will not work.
Specific breakdowns of Whirlpool machines
In Whirlpool dishwashers, according to the same statistics, the inlet valve most often fails. In order to repair Whirlpool dishwashers in this case, you need to accurately understand whether its electrical part has broken down - the coil or the mechanical part. If the electrics fail, the valve must be replaced; if the mechanical part breaks down, there is a chance to revive the part. What actions need to be taken?
- Turn off the machine, and then unscrew the front panel located immediately under the door.
- On the front left side of the machine you will see a fill valve with a hose connected to it.
- We disconnect the wires from the coil of this valve and install ohmmeter probes on the contacts. We set the minimum resistance value on the device and begin measurement. If the device shows a value from 500 to 1500 Ohms, the intake valve electrics are fully operational; if the resistance is much greater than or less than these values, the valve is broken.
- If the electrics are working properly, but the valve still does not work, most likely it is clogged with lime deposits; you need to unscrew its body and clean the mechanism.
If after the above manipulations the operation of the valve is not restored, it needs to be replaced. As you can see, repairing Whirlpool dishwashers, at least for this fault, is not difficult. Any good owner will make it with his own hands without any problems.
Specific breakdowns of Krona and Kuppersbusch machines
The main weak point of Krona dishwashers is generally considered to be the control module. While the other parts of this dishwasher are quite reliable, problems often occur with the control unit. In 99% of cases, there is a manufacturing defect, either the tracks are poorly soldered, or the board elements do not connect well. Some experts are of the opinion that the manufacturer has begun purchasing control modules for its machines in China, but it is not possible to verify this information.
Important! If you suspect that the control module has failed and the dishwasher is under warranty, immediately call a technician and send the machine to a service center for repairs.
How to repair Krona dishwashers? In this case, we can definitely say – you shouldn’t do the repairs yourself. The control module is an expensive part; unskilled repairs can completely ruin it and you will have to buy a new module, spending about $100. It’s better to contact a specialist right away - it will cost less. Our technicians repair Krona dishwashers quickly and professionally, saving you time and nerves.
If the control module of Krona dishwashers breaks down more often, then there are not even statistics on the frequent breakdowns of Kuppersbusch dishwashers.Does this mean that repairs to Kuppersbusch dishwashers are required so rarely that there is no point in keeping such statistics, or is the manufacturer making efforts to prevent such information from reaching the consumer? With great difficulty, we managed to obtain some information from several craftsmen who claim that repair of Kuppersbusch dishwashers is most often required when their on/off button breaks.
The symptoms of a breakdown in this case are simple - the dishwasher stops turning on and off with the button. How to repair Kuppersbusch dishwashers in this case?
- Open the dishwasher door.
- Take a Phillips screwdriver and unscrew the inner wall of its door.
- Unscrew the control panel and clean the contacts of the on/off button. Very often, contacts become oxidized due to moisture and stop functioning. Cleaning it up helps for a while, but the problem may recur in the future.
- We screw the control panel into place, assemble the door and check the operation of the dishwasher.
To summarize, we note that the repair of industrial dishwashers, just like the repair of household ones, cannot always be done with your own hands. Of course, a lot depends on the skills and aspirations of the user, but most often it is better to entrust the repair to a professional, because “the health of your iron assistant” is at stake. Good luck!

Good advice! Thank you!
Where is everyone’s favorite Bosch!?
Good afternoon. The dishwasher runs for 15-20 minutes, then knocks out the plugs. Wiring is ok. I opened the pan and it is dry. What kind of malfunction?
