Symptoms of a bad diverter cover include: Leaks from the diverter valve area Difficulty with water diversion during cycles Reduced spray pressure or coverage inside the wash compartment Debris accumulating near the valve mechanism This OEM replacement is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.Part Number WPW10455271 (AP6021681) replaces W10315328, W10455271, 4447086, PS11755007.
