The Check Valve Flapper is an OEM replacement part for GE dishwashers. It is a small but crucial component located within the water inlet valve assembly. The check valve flapper regulates water flow into the dishwasher, allowing water to enter during the fill cycles but preventing backflow when the water is drained.  Causes of a bad check valve flapper can include wear and tear over time, mineral buildup that causes sticking, or damage to the flapper itself. This prevents the flapper from opening and closing as intended. Symptoms of a bad check valve flapper include: Slow or incomplete filling of water  Dripping or leaking water from the inlet area Error codes related to water issues This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore dishwasher models. This part fixes the following symptomsWill not drainPart Number WD01X10175 (AP3419048) replaces 911985, AH258167, EA258167, PS258167, WD01X10178, WD01X1486, WD1X10175, WD1X10178, WD1X1486, WH01X10235.
