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. Bob

I suspect you are on the right track with the control board. It is accessed for replacement by removing the screws from the inner door and separating the panels. The control connections will unplug and plug in and are keyed so that they will only fit in one way. I would still mark each connector to be sure, or replace them one at a time. Also, taking pictures as you disassemble may help with reassembly.

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.

I believe they are a T15 Torx head. They look like a star, correct?

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.

Great! Those are a T15 or T20 Torx head, available at any hardware store. Let me know how it goes!

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 )

The excerpt from the service manual below should help. Appliance Ninja attached the following image(s):

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.

That is pretty odd. The main wash motor starts and recirculates the water, correct?
