KitchenAid dishwasher not responding/requiring cold reboot
How old is the circuit breaker? I had similar problems in the past where an outlet or appliance wasn't working and the breaker appeared to be open, only to find out it in fact was tripped. I could reset it, but in a short time , I would have the same problem. It turned out that the breaker was old and weak. It would appear to be open, but with the slightest touch, it would trip. Does it take a bit of effort to trip (turn off) the breaker when you reset it? If not, then a new breaker may be the solution.
