What does the switch sensor do? My dishwasher will run and then on the rinse-dry cycle it stops and the normal button/light beeps. Thanks.
The sensor switch is for the activation of the detergent lever. With the unit stopping in the rinse dry cycle and the normal light beeping, then the issue would most likely be in the control board. You will want to access the tech sheet behind the kick plate and run a service diagnostics to make sure that everything checks ok. If the unit completes the diagnostic then the control board would need to be replaced.
