Cycles On When Door Is Closed

Need help with this problem…The normal cycle stars and is completed. The dishwasher then starts the normal cycle on its own…no buttons presed. To stop the cycle I press the cancel button the unit will stop and the lock light blinks. If I open and close the front door the unit will start in normal cycle on its own.
operation panel or control board?

Seems like a shorted key pad. No way to test, just order a new one.
