I’ve had my control panel go bad 3x in 6 years. Stupid touchpad

Anyways I get three blinking lights when I press start. But if I power off at the breaker I can get it to run once. Then when I open and close the door, the clean light or whateve it says won’t turn off unless I hit cancel. Then the start button goes back to blinking 3x until I power cycle again

Any suggestions?

It sounds like a problem in the control board, but check all your wiring connectors on the control board to make sure none are loose.

Also check your control board and see if you notice any burnt spots on it.

Also look for a break or short in the wiring coming up from the wire harness where it goes into the door.

Also check your control panel ribbon cable to see if its loose or corroded on the end of it where it plugs into the control board.

Here's the control board for your model:
