As long as you have power to the unit then the control board has failed, so you need to replace it. Part#00488428. It's in the console and has the display on it.
That's fine, but to be perfectly fair I did say "as long as you have power to the dishwasher" so I WAS corrrect in what I said. I did not say the control was bad with no other option.
There is clearly a loose connection where that electrical connection is made to the unit based on your reply.
