Possible Causes
Loose hose clamp on circulation or drain hose, Cracked sump or tub, Leaking circulation pump seal, Split inlet hose inside cabinet
How to Fix / Troubleshooting
Safety first: Unplug the dishwasher and close the water tap immediately. Mop up any spilled water to avoid slipping.
- Pull out the dishwasher: Carefully slide the unit out of the cabinet to inspect the sides and bottom.
- Visual inspection: Remove the bottom panel and run a short cycle while observing (use a flashlight). Look for drips from hoses, pump, sump, or tub seams.
- Tighten clamps: If a hose connection is seeping, tighten the clamp or replace it if corroded.
- Replace damaged parts: A cracked sump, leaking pump seal, or split hose must be replaced. Use OEM Hansa-compatible parts.
If the tub itself is cracked, repair may not be economical and a full tub replacement or new appliance may be required.
