Start button does not respond

I have a GE Profile Quiet Power 7 Dishwasher that is acting up. I woke up this morning to find that the dishwasher ran all night. When I opened it up, the display read 888 and all the LEDs were lit up. I tried to reset by pressing START and nothing happened. Then I turned off the breaker for a couple of minutes turned it back on and now all buttons worked except for START. Took the front panel off and then pressed START and now it worked. Ran through a complete cycle, but can’t get START to respond again. Anybody have any suggestions on what I might try next? Thanks!
