Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Water pooling beneath the center or rear of the dishwasher.
• A leak localized around the sump, pump, or diverter-seal area.

Check Before Replacing

• With power off, inspect the area beneath the unit to identify whether moisture begins near the center/rear sump area versus a hose or inlet/drain connection.
• Check pump-hose clamps and hose connections for looseness, damage, or signs of leakage before attributing a leak to the sump assembly.
• Remove and rinse the filter, then check the accessible sump/drain path for debris or blockage.
• If water remains after a cycle, check the drain hose for blockage before diagnosing the sump assembly.

Pro Tip

Part Details

Key Features

• Genuine Whirlpool OEM dishwasher sump housing and diverter-motor assembly.
• Designed for KitchenAid, Maytag, and Whirlpool dishwashers.
• The assembly is identified as the sump and diverter motor; it is not the complete wash-motor-and-drain-pump assembly.

Installation Notes

• Disconnect electrical power before servicing. If there is an active leak, shut off the water supply and do not run the dishwasher until the source is corrected.
• Replacement requires dishwasher disassembly to access the sump from inside the tub; confirm the exact model before installation.
• Avoid damaging or scoring the plastic sump shaft/seal area during related diverter-seal service, as Whirlpool warns that damage can create a future leak path.
