Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes remain poorly cleaned despite normal filling and draining.
• Weak or absent water flow from one or more spray arms.
• Water leakage near the sump, diverter, or bottom of the dishwasher if the cover is cracked, warped, improperly seated, or missing its seal.
• Possible abnormal wash-water behavior caused by a damaged pump outlet cover.

Check Before Replacing

• Disconnect electrical power before inspecting the sump or pump-cover area.
• Inspect the cover for visible cracks, warping, distortion, missing sections, or an improperly seated seal.
• Check for debris around the sump and pump-outlet area without forcing or damaging components.
• After confirming the dishwasher model, compare the installed cover and seal with the replacement part before ordering.
• If wash performance is poor, verify that the spray arms are unobstructed and that the symptom is not caused by a separate circulation-pump, diverter, filter, or spray-arm problem.
