Whirlpool WP3378138 Dishwasher Detergent Dispenser Cover / Soap Cup Lid
Whirlpool WP3378138 Dishwasher Detergent Dispenser Cover / Soap Cup Lid
Replace a broken soap-cup door with genuine Whirlpool WP3378138 detergent dispenser cover. This molded lid seals detergent inside the dishwasher dispenser until the cycle triggers the latch. It is a single cover, not the complete detergent dispenser or a multi-piece repair kit.
