Our Bosch dishwasher cycle time in Auto Wash went from 110 min to 144 min. I cleaned the filters and sensor and the wash time went back to 110 for one wash cycle. Now the wash time is back to 144 and the washer cycles on and off three times and then stops running right after the soap dispenses for the wash cycle. From my research it appears to be a faulty Control Board. I've ordered the part but I'm not sure if it will fix the problem or how to install the new Control Module. Any help or suggestions would be greatly appreciated. Thanks.

The screws on the inner door look more like rivets than screws. Is there a specific tool required to remove the door to separate the panels? Thanks again for taking the time to address my questions.

They do look like a star. Just making sure I remove the correct screws. The replacement part won't arrive for a couple days. I'll post how the replacement process works out and if it corrects the problem. Thanks again.

The control board should be delivered today. I've accessed the control board in perpetration to make the repair but I'm not sure how to remove it. Having the new part might give me a better idea, but I'm trying to get a head start before the part arrives. I'm tired of hand washing dishes )

Thanks for the service manual excerpt. I installed the new control module and unfortunately I'm still having the same issue. The wash cycle begins normally but around 85 min remaining the detergent dispenser door opens and the wash cycle starts and then quickly stops and starts 3 times and then the dish washer stops. If you open and close the door it starts and stops again 3 times and then stops. The time continues to count down and the washer drains at the end of the cycle. Suggestions are greatly appreciated.
