Whirlpool WP3378138 Soap Dispenser Cover for Dishwasher

The Whirlpool WP3378138 Dishwasher Soap Dispenser Cover is a component of the detergent distribution system in dishwashers. This part is compatible with various dishwasher models, including those from Whirlpool, Roper, and Maytag. It functions as a protective lid for the detergent chamber within the dispenser. During the wash cycle, the cover remains securely latched, holding the detergent in place until the designated moment for release. At that time, an internal mechanism disengages the latch, allowing the detergent to flow into the wash tub. A properly functioning dispenser cover is essential for preventing premature detergent release, which could lead to waste or reduced cleaning efficiency. If the cover is damaged or malfunctioning, it may prevent the dishwasher from dispensing detergent altogether, resulting in unsatisfactory cleaning outcomes.
