Checked power with voltage tester. Power went to board and door latch. Read a bit that the door latch switches faulted. Call appliance parts spoke to a young lady who was very helpful in reviewing my issue. She informed me that I could return the part if it did not fix the problem. I ordered the door latch. Received in two business days, replaced it and dishwasher is working again. One safety note - turn the power off . There is a bit of an exposed part of the prongs on the switch that don't full get covered by the connectors. Low and behold the latch slipped out of my hand and the prong somehow touched the metal of washer, sparked and breaker tripped. Fortunately I'd did not burn out the switch. Lesson learned. Also note that beside a Phillips screwdriver you need a star tip screwdriver or bit if a ratchet type screwdriver which I used.
