Bosch dishwasher repair
Despite the high quality of German assembly, Bosch dishwashers, just like any other, can fail. There is no ideal technology; a dishwasher is a complex electrical appliance, the operation of which depends on many factors. Therefore, the dishwasher may break down at one point. How to repair Bosch dishwashers yourself, what breakdowns happen most often - we’ll talk about this.
Typical faults
In most cases, if any malfunction occurs, dishwasher users contact service centers. However, this is not justified in all cases; sometimes the problem can be fixed with your own hands. Here are the most common malfunctions:
- the machine does not take in water;
- Water remains in the dishwasher and does not drain;
- The dishwasher does not wash the dishes and freezes.
Before you panic and call a technician, try resuscitating the washing machine yourself. If the machine does not fill with water, then it is worth checking whether the water supply tap is open. When the machine does not work (does not turn on), the socket may be faulty, replacing it will solve the problem. In addition, the machine may not turn on if the door is not closed properly. Before calling a technician, you can also check the filters for blockages.
If these simple techniques do not help restore the dishwasher to working order, then diagnostics of the machine components is required.
“Sores” of Bosch dishwashers
In addition to the above listed malfunctions, the Bosch dishwasher is characterized by Aqua stop operation. Craftsmen call such a breakdown a “sore” of these dishwashers.This error appears as follows: the display shows error code E15, the machine does not fill with water for washing, there is a water leak inside the machine.
This problem can be solved quite simply. First, the equipment is disconnected from the electrical network for safety reasons. The dishwasher is then carefully tilted to drain the water from the tray. In this case, the slope should be about 450. This will also allow the sensor float to be released from being stuck in the “water” position.
For your information! Sometimes it is enough to move the dishwasher from side to side to move the float and eliminate error E15.
Another characteristic problem with Bosch dishwashers is the gasket in the inlet hose. If the gasket is placed on the wrong side, the hose will leak water or there will be no water supply. Therefore, when connecting the water supply, you need to follow only the instructions.
Dishwasher does not drain or fill with water
Now let's figure out what to do when the machine seems to be working, but no water is flowing into it. One of the reasons has already been described above - this is the activation of the Aqua Stop. The second reason is a clog in the filter installed on the water inlet. It is easy to clean with your own hands. To do this, unscrew the inlet hose, then carefully use pliers to remove the mesh and rinse it under running water.
A more serious breakdown may be the failure of the filling valve, which is located immediately behind the filter. In most cases, it must not be repaired, but replaced. You can check the valve contacts using a multimeter, but in addition to the electrical part, a mechanical breakdown may occur in the valve, causing the valve to jam in the closed position. There is information about all the reasons for the lack of water filling in the article Water does not flow into the dishwasher. This publication describes in detail why water does not get into the dishwasher, including a video with additional explanations.
The opposite problem when the dishwasher does not work is a situation where there is no drain. In this case, there is water in the machine chamber and the machine freezes at the washing or rinsing stage. The main reasons in the case of Bosch dishwashers are:
- clogging of cleaning filters - if you neglect basic operating rules, the problem can be easily solved with your own hands;
- kink in the drain hose;
- pump failure.
Clearing a clogged filter with your own hands is as easy as shelling pears. At the bottom of the dishwasher tank there is a flat metal mesh, and next to it there is a glass-like element - these are fine and coarse filters. These filters are easy to remove, wash, and then put back in place. Everything will take no more than 10 minutes.
To check whether the drain hose is kinked, you need to look behind the body of the machine and see how the hose is installed, and most importantly, whether the machine is standing on it. If everything is fine with the hose, then the cause of the problem is somewhere else. To replace and check the pump, you need to get to it through the bottom of the dishwasher. Before replacing your pump, make sure it is broken by checking with a multimeter.
The resistance of the working winding should be about 1000 Ohms. In general, such a malfunction is a complex repair, so before you do it yourself, think about whether you can handle it.
The machine does not wash and freezes
If your Bosch dishwasher does not work normally, freezes in the middle of a program, or refuses to wash at all, there can be many reasons.This symptom is one of the most abstract, because at first glance, it cannot answer the question of what is the cause of the malfunction, but let’s not despair. First, let's define a general list of what could break in a Bosch dishwasher if it freezes?
- General failure of the electronic part - in this case, the problem is solved by restarting the dishwasher (after which it usually works).
- Failure of the control module - in this case, independent diagnosis and repair are almost impossible.
- The self-diagnosis system has worked, and the control module generates an error corresponding to a specific breakdown, until the breakdown is fixed, the machine will not work.
- The door of the washing tank does not close tightly. Bosch dishwasher doors have a special locking mechanism and a corresponding sensor that controls this mechanism. If the sensor is faulty or the door is open, the machine will freeze and will no longer work. The problem is solved by replacing the door sensor or its mechanism.
The above reasons are more common in Bosch dishwashers, but in general the list of reasons for dishwashers freezing is much wider. Now let's look at examples of reasons why a Bosch dishwasher does not wash dishes?
- No water.
- The pressure switch does not work.
- There is a malfunction in the circulation pump.
- The control module triac burned out.
You can read more about the reasons why a Bosch dishwasher refuses to wash dishes in the article of the same name Dishwasher doesn't wash dishes. In addition, the article contains recommendations for troubleshooting, as well as a video on this topic.
In conclusion, we note that Bosch dishwashers can be found in every third dishwasher owner, this makes Bosch the most popular brand among consumers, and accordingly, there are many more cases of breakdowns of such machines, and there are even more reasons. We tried to review them in this article, supporting the text with the video. We hope you find it useful.

Hello, my Bosch dishwasher washes, but does not heat the water or dry it, after I tried to set the water hardness higher because it left a residue, what should I do?
Hello. The machine draws water, then the faucet indicator lights up and nothing else.
Hello, the dishwasher fills with water and starts leaking when it is not working, can you tell me what to do?
Bosch dishwasher. When you turn on the machine, the drain pump starts and runs indefinitely.
The “Crane” indicator is flashing and the “Snowflake” light is on, while there is some kind of hum. The washing machine does not respond to the buttons or opening/closing the door.
Snowflake is to add rinse aid.
The machine is humming, what is that?
Good evening! Please tell me. Bosch dishwasher.After turning on, the drying indicator lights up after 3 seconds and the machine no longer responds.
Good afternoon. Compact Bosch dishwasher, in three out of four cases there is a white coating on the dishes after washing. There are no errors. Salt and rinse aid added. What are the possible reasons?
