I have a KitchenAid 2 drawer dishwasher, model # KUDD01DPPA 1, that is continually running and beeping (both units). They both show red lights in the center (on) and the lock lights are also illuminated…but when you open each, the Rinse light is on. The only way to get them to stop is to cut power. If pulled the lower tub and looked under the cover at the circuit board, but it’s bone dry. Any suggestions? Thanks.
