✅ 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.

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.
