No lights flashing; no error messages. The wash cycle works normally. The dryer cycle stops after a random number of minutes - before the cycle is complete - just stops - nothing else
The sounds of the cycle are completely normal until it stops prematurely.
I appreciate the effort, but I believe the conclusion is that I have to open a service call with Bosch. I'm an average person, not a technician, and I certainly don't have equipment on hand to measure MOhms. Thanks for trying - I'm calling Bosch now.
