Hi,
I had a similar malfunction with my bosch dishwasher, it stopped mid cycle, no error showing at the display, only the time 0:00nd check water supply light on.
Guess what, the flow sensor was broken at on side, the glass have a crack. When heating, a malfunction occurs.
Sensor replaced, dishwasher works fine.
Thansks cyrex86 and Javeff , yours posts and coments helped me to fix my dishwasher.
