When we cannot detect the error on the dishwasher’s control board, what next? An inexperienced handyman will hardly notice any problems with it. The wires might be disconnected (burnt) under the baddie of some in a row or may have been broken somewhere before reaching the junction point. Diagnosis should include checking all these points in order:

  1. the heating element
  2. wires
  3. thermostat
  4. If the above does not solve the issue, then check the control module.

You can locate the heating element relay by removing the Bosch dishwasher’s lower front panel. Generally, it is easy to locate the heating element relay on the board. There should be at least one wire connecting from the heater to a part on the board. If this is your case, a qualified specialist can replace that wire and it will be less expensive than buying a new circuit board.

It is very expensive to repair a control module. In many cases, simply replacing the heating element will solve the issue. Bosch dishwashers are usually expensive and that’s why Bosch manufactures parts for Bosch dishwashers so you can replace the Bosch dishwasher control module yourself. You will also save enough money if you have a Bosch repair manual.

Before you replace the board, carefully examine all wires and sockets. Take pictures of the wiring, so that you know what your are doing.
