Recently our dishwasher stopped running. The 'clean' light was on and would flash if you tried to start the cycle. Apparently this happens if there is a fault (generic - many things cause it) and can be cleared by pushing NORMAL WASH and HEATED DRY in sequence 2-3 times. I did this on ours and it cleared the fault and has been running properly since. There may be an issue that causes it to trip again in which case I will investigate further but often times, it is a fluke that causes the issue and it may never be an issue again.
