I tried simply resetting by turning breaker off then on. That worked once. Problem reappeared and so started looking at various appliance blogs and YouTube videos. In the end I discovered the technician sheet under the kick panel (panel at the bottom of Machine) and it had a very Complete and clear diagnostic procedure that pointed to a shorted button or buttons on the panel. I pulled the panel out, cleaned it as best I could, dried it and put it back in. That worked for a few cycles but then problem came back. So I ordered a new part, it came fast and I installed. Problem appears to be resolved.
