After further inspection I found 2 wires wore apart where the door hinges. I repaired the wires and the dishwasher came to life, but it would only fill and drain. The timer advanced ok. I checked the circulation pump and it wasn't working and the motor was burning hot and smelled bad. I unplugged machine and told the customer it needed a new motor. Is it possible for something to get stuck in the pump considering how small the drain holes and screen are?
