The German company Bosch is one of the highest quality on the market, but no one is perfect, so we have prepared for you a list of the most common breakdowns.


Can’t get any water in

If the German brand dishwasher refuses to draw water, the problem may lie in the circulation pump or in the hose. You can fix it yourself, simply by replacing these elements.


Very often the water does not come because there is not enough pressure in the water system.


No drain

No drain means that there is a leak somewhere or the drain hose is out of order. Also, very often the problem is the presence of kinks. The Bosch dishwasher manual clearly states that the hose should be as straight as possible, without any bends or other obstructions.


Not drying the dishes

If the dishwasher does not dry the dishes, it is necessary to check the board and control unit, which are responsible for this mode. It should be noted that if there are problems, it is quite difficult to repair them, so in most cases, you have to make a complete replacement.


These elements can malfunction due to interruptions in the voltage network or due to illiterate use of the dishwasher.



Clogs are the reason for untimely inspection and maintenance of all the technical parts of the Bosch dishwasher. If the filters are not cleaned on a regular basis, they will begin to fill with various food residues and other impurities, which will cause the dishwasher to stop performing its functions.


You can solve this problem by cleaning the hoses and other elements in which the clog is observed.


The tablet does not dissolve

The only reason why the tablet may not dissolve is due to a problem with the control unit, which does not allow the dishwasher to detect the presence of detergent and use it.


A thorough diagnosis should be performed to make sure there are no software malfunctions.


Does not wash properly

There can be many reasons why a Bosch dishwasher does not wash dishes well. It is often a consequence of poor water heating, broken sprinklers, insufficient use of detergents, and so on. The only way to determine the source of the problem is to remove the lid and find possible shortcomings in the operation of this unit. In addition, it is necessary to study the manual to make sure that the loading of dishes, as well as detergents, is correct, according to the manufacturer’s recommendations.


No water heating

One of the most common problems is the failure of the heating element. If the water is not heating, then the heater is most likely broken. The main reason for this is hard water.


That is why experts recommend using salt every time you wash dishes, which prevents the formation of limescale and protects all elements of the dishwasher.


Weird noises

The main reason for the presence of unusual sounds during the operation of the Bosch dishwasher is the wear and tear of the bearings. The culprit is water, which very often ends up on the bearings due to a failed oil seal. The grease is washed out, as a result of which this element begins to hum strongly and create discomfort while using the unit.


The only way to get rid of this problem is to completely replace the bearings and packing.


Faulty doors

If the dishwasher from this brand does not want to turn on or start a certain mode, the cause may be faulty doors. In this case, the display will show the corresponding information with an error code, which will tell you that it is not closed tightly. It is necessary to open the door, make sure of the integrity of all elements or fix them if there are problems. Very often this failure occurs due to rough handling, slamming, or opening too much.


It is necessary to fix all parts and make sure that the door is as tight as possible. If the door closes but does not fit tightly, then the problem is in the lock, and it can be repaired by simply replacing it with a new one.


So, despite the fact that dishwashers from Bosch are one of the highest quality and in demand on the market, even they can fail from time to time. Before carrying out repairs, it is necessary to clearly find out the cause of this problem and only after that try to fix it.


The main assistant in this process will be the user manual, which includes information on all possible errors, their codes, and ways to fix them.


In some cases, it is better not to carry out the repair with your own hands, but to turn to a specialized technician. Chula Vista Appliance Repair Company will promptly come out and fix the problem
