Bosch dishwasher no display on start button pushed

Dishwasher Repair

Brand:Bosch
Model Number: shx65t55uc/07
Main Symptom:no response
What happens & when: Dishwasher has no power while pushing the start button. I’ve detected there’s voltage power up to the power button. So far I’ve replaced the power button and the UI control module and also the door latch but still no display and reaction. Should I replace the Bosch main control module?

Does the main module takes power from the UI control module or can the main control module affects the power supply and UI display on the UI control module?

Thank you!

That is not a bad idea, the part is on the bottom base on the right side. The DW will have to be pulled out. We show the board as NLA, you might try some online auction websites. 12008382

Looks like it’s still available. I’ve ordered the main control module 12009532 Control Module (Programmed) | Genuine Bosch OEM In Stock. I hope I ordered the right one. Thank you!

Update: Replacing the main control module does fix the problem. I was replacing a bad water pump and rotated the dishwasher to access the pump. I think the water got into the main control module. Lesson learned, never rotate the dishwasher. :sweat_smile:
