Dishwasher signaled code “–” and led above keys blinking normal, push cancel and 2 minute cycle runs out. Replaced 2 micro switches for door sensor. This worked for one run through then went to a loop of restarting it self to a normal cycle. When you press cancel it will stop for 2 minutes than try to cycle again. Then changed circuit board, now it only has normal blinking light above normal and does not run at all.
Pull the service data sheet behind the kick panel and enter in the pushbutton code for entering diagnostic mode, then hit cancell, should reset computer.
Tried and the board doesn’t respond to a reset.

You might have a stuck keypad. Might have to change the control panel AP3176986 a bit pricey.Remove the ribbon cable to the control panel and see if the lights still flash, if not, you have a bad keypad in the control panel.
