Dishwasher has power and panel lights are on. When start button is pushed it flashes continuously and beeps 3 times every minute. Ran Error Codes, indicated door switch not closed. Door switch and it's wiring harness all check out good to mult-pin connector at main control board. Washer cycle was stopped during a lightening storm and was subject to either a power outage or voltage problem. I suspect the main control board was damaged but can't confirm that. I shows no physical damage. How can I confirm the status of main control board without just swapping it out? I have been waiting 3 days for GE help website to answer my questions. Does anyone have any suggestions? I tried several times to reboot it by tuning off the power for 5+ minutes with no change, control still thinks the door switch is not closed.Thanks
