This auto washer goes through phases where it repeatedly stops mid cycle and needs the stop/start button pressing to get it going again. Sometimes it only holds in for a few seconds before stopping again. It can happen at any part of the cycle, so because i'm looking for something common to everything, my suspiscions fell on the door catch, but when I took off the top to check it, the fault refused to reappear. Anyone got any tips (or circuit diagrams)?
