I have a problem with my kitchenaid dishwasher model #kudco31vwh3 . The normal wash light is flashing and won't stop when the door is opened. I have turned the breaker off and when it is turned back on the dishwasher starts its cycle but soon stops and the light starts flashing . I have done the 123 123 123 sequence with the door open then shut to start the diagnostic test. That didn't work. The washer started the wash cycle,stopped and the light started flashing again. When the cancel button is pushed,both lights flash. Any ideas?
