How to get rid of the E15 error of Bosch dishwasher

If you got the message about the error, so most likely your Bosch dishwasher stopped in the middle of a cycle because of power failure or the aqua-stop system work.

The dishwashers do not like it, that is, they do not like to be interrupted in the process of important work.


Before carrying out any work, make sure that the dishwasher is disconnected from the mains and is not under tension.

To get rid of the E15 error code of your Bosch dishwasher, you have to turn off the machine and unplug the power cord. Wait for a couple of minutes for the system to reset. Then turn on the device and run the program again.

In the cases when the E15 fault is caused by the water leakage sensor malfunction, it can be fixed independently. The sensor float could simply “stuck”. You have to carefully shake the washer from side to side. Then drain the water and leave to dry.

Leak sensor failure

To prevent the water penetration into the lower part of the body, you should pay attention to the exact dosing of a detergent, and also be sure that the dishes with the remains of soap are not in a sink. The fault can be also caused by the excessive amount of foam that penetrates into the absorbent layer of the aqua-stop system in the pan.

The clogged water drainage system of Bosch dishwashers requires more efforts for the problem elimination. Remove the dishwasher from the kitchen to open the left side cover completely. Use old towels or rags to absorb the water from the bottom of the device.

Blockage of the drainage system

Carefully remove the filter, located at the bottom of the dishwasher drum and rinse it under the running water. It could be littered with food debris or excess detergent. Take everything back and put the dishwasher back into its location and connect it to the power supply.

Thus, the problem of the E15 error appearance of Bosch dishwashers will be solved by your own.

However, if all the above-mentioned recommendations do not work, the help of a specialist is required because the problem can hide in the control board or in something else.
