Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Leak beneath or near the center of the dishwasher tub
• Damaged, deteriorated, or separated sump seal causing leakage
• Reduced wash-water circulation when the sump or its connected passages are obstructed

Check Before Replacing

• Disconnect power and water supply before inspection or service.
• Inspect the bottom-center underside of the tub for fresh water or mineral residue after a cycle; distinguish the sump area from nearby hoses, pump seals, and inlet connections.
• Remove and rinse the dishwasher filter, then inspect the exposed sump opening for visible food debris or foreign objects without probing or disassembling the assembly.
• Confirm that the spray arms can rotate freely and that their openings are not blocked; poor spray performance is not by itself proof that the sump has failed.
