Hello,
Our 6 year old bosch dishwasher had the control module relay fry( K1 relay-smoked/burned the old board ). Just before this happened, it would stay on the last min of the counter for a while.
1. Replaced the Control module and the circulation pump does not come on. It just fills with water and drains a little, kinda pulses with water in and draining. When you cancel the cycle it drains fine. Would say you could smell an electric burning type odor when this was first installed, but that could be from the old board. The old board seemed to get very hot when the relay burned.
2. Replaced the Circulation pump with a brand new one and it does the same thing!! I tried adding a couple cups of hot water when it was filled with water to see if the increased water level would cause the circulation pump to come on, but no changes. The old motor seemed to be fine, no play in the bearings or impeller.
It should be repairable and I would hate to throw this away for a simple fix. Ideas to troubleshoot this would be greatly appreciated.

Replaced the Water heater, which included the NTC sensor, aqua sensor, and other switches that are part of the Heater assembly. New float switch and a new water inlet valve. It does the same thing, fills and drains! Fill and drain musical beat non stop. The dishwasher drains fine when you cancel a cycle.
At this point I am down to a few original parts such as the drain pump and soap dispenser. Also the 186963 PC board and the wiring. Unless the new control module was bad.
Starting to feel that I should have ordered a new one when the control module burned up.
