Parts for Craftsman 917255540: Drive Control / Gear Case / Wheels Parts

This is an optical sensor switch located in the rinse-aid dispenser of a dishwasher. It uses a light sensor to detect the level of rinse-aid remaining in the reservoir and signals the control board when a refill is needed. Replace this sensor if the rinse-aid indicator light stays on constantly, never illuminates, or if dishes come out with spots and streaks despite a full rinse-aid reservoir.
