Repair of Bosch dishwashers

Bosch dishwasher repairDespite the high quality of the German assembly, Bosch dishwashers as well as any others can fail. There is no perfect technique; a dishwasher is a complex electrical appliance, the operation of which depends on many factors. Therefore, the dishwasher may one day break. How to repair Bosch dishwashers yourself, what kind of breakdowns happen most often - we'll talk about that.

Typical malfunctions

In most cases, when any malfunction occurs, users of dishwashers turn to service centers. However, not in all cases this is justified, sometimes the problem can be eliminated with your own hands. Here are the most common malfunctions:

  • the machine does not pick up water;
  • water remains in the dishwasher and does not drain;
  • the dishwasher does not wash the dishes and freezes.

Before you panic and call the master, try to reanimate the car yourself. If the machine does not fill, then it is worth checking whether the water supply tap is open. When the machine does not work (does not turn on), then the outlet may have failed, replacing which will solve the problem. In addition, the machine may not turn on if the door is not closed properly. Before calling the wizard, you can also check the filters for blockages.

If these simple tricks did not help restore the dishwasher's performance, then diagnostics of the machine components are required.

"Sores" dishwasher Bosch

In addition to the above listed faults, the Bosch dishwasher is characterized by the activation of an Aqua stop. Masters call such a breakdown the "sore" of these dishwashers. This error appears as follows: appears on the displayerror code E15, the machine does not fill in the washing water, a leakage of water has occurred inside the machine.

This problem is solved quite simply. First, the equipment is disconnected from the electrical network for safety reasons. Then the dishwasher is carefully tilted to drain the water from the pan. In this case, the slope should be about 450. This will also allow the sensor float to be removed from the sticking state in the “water” position.

Note! Sometimes it’s enough to move the dishwasher from side to side to move the float and eliminate the error E15.

Another characteristic “sore” Bosch dishwasher is gasket in the inlet hose. If the gasket is put on the wrong side, the hose will leak water or there will be no water collection. Therefore, when connecting the water supply, you must be guided only by the instructions.

Dishwasher does not drain or fill water

hose filterNow we will figure out what to do when the car seems to be working, but water does not enter it. One of the reasons already described above is the activation of the Aqua Stop. The second reason is a blockage in the filter installed on the water inlet. It is easy to clean with its own hands. To do this, unscrew the inlet hose, then gently with pliers you need to get the mesh and rinse it under running water.

A more serious failure can be the failure of the filling valve, which is located immediately after the filter. In most cases, it must not be repaired, but replaced. You can check the valve contacts with a multimeter, but in addition to the electrical part, mechanical damage to the valve, jamming of the sash in the closed position can occur. For all the reasons for the lack of a gulf of water there is information in the article No water entering 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 is not working, is the lack of a drain. In this case, there is water in the machine’s chamber, the machine freezes during the washing or rinsing phase. The main reasons in the case of Bosch dishwashers are:Bosch dishwasher repair

  • clogged cleaning filters - if you neglect the basic rules of operation, the problem is solved easily with your own hands;
  • kink of the drain hose;
  • pump breakdown.

Do it yourself with a do-it-yourself filter clog. At the bottom of the dishwasher tank there is a flat metal mesh, and next to it a glass-like element is fine and rough filters. These filters are easily removed, washed, and then put in place. It will take no more than 10 minutes.

To check if the drain hose is bent, it is necessary to look behind the machine body and see how the hose is installed, and most importantly - whether the machine is standing on it. If everything is normal with a hose, then the cause of the problem is different. To replace and check the pump, you need to get to it through the bottom of the dishwasher. Before changing the pump, make sure that it is broken by checking this with a multimeter.

The resistance of the working winding should be about 1000 ohms. In general, such a malfunction relates to complex repairs, so before you do it yourself, think about whether you can handle it.

The machine does not wash and freezes

dishwasher repairIf the 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 us the question of what is the cause of the malfunction, but we will not despair. First, let's decide on a general list of what could break in a Bosch dishwasher if it freezes?

  1. General failure of the electronic part - in this case, the problem is solved by rebooting the dishwasher (after that it usually works).
  2. Damage to the control module - in this case, independent diagnostics and repairs are almost impossible.
  3. The self-diagnosis system worked, while the control module generates an error corresponding to a specific failure, until the failure is eliminated, the machine will not work.
  4. The door of the washing tank does not close tightly. The doors of Bosch dishwashers have a special locking mechanism and a corresponding sensor, which controls this mechanism. If the sensor is defective or the door is open, the machine will freeze and will not work further. 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 to hang 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 triac of the control module burned out.

You can read more about the reasons why the Bosch dishwasher refuses to wash dishes in the article of the same name The dishwasher does not wash the dishes. In addition, the article contains recommendations for troubleshooting, as well as a video dedicated to this topic.

In conclusion, we note that Bosch dishwashers can be found in every third owner of a dishwasher, which makes Bosch the most popular brand among consumers, respectively, there are much more cases of breakdowns of such machines, and there are even more reasons. We tried to review them in this article, reinforcing the text of the video. We hope you find it useful.
