I was convinced I had a door latch problem because of intermittent starting, bypassed the micro-switch, eliminated it as the problem.
Read others commenting on line, and the fact that not all keypads worked pointed to the Panel Control.
Ordered the new panel, installed in minutes, works like new now.
I probably saved at least $100 for a repairman's " mobilization fee" and "opinion"
Delivery was less than two days , so actual dish washing by hand didn't last too long.
