Bought a replacement controller.
Unplugged the power.
Removed front cover of the door.
Unplugged the wires and the old controller snapped out.
Snapped the new controller in and connected the wires.
Reinstalled the cover on the door.
Plugged the power in and I was finished.
The whole thing took about 15 minutes.
The dishwasher works great, 90 minute run time.
Couldn't be easrier, but you will need a torx driver.
