How to Fix / Troubleshooting
Safety First: Disconnect power and shut off water supply.
Dry the base and inspect:
- Remove the lower access panel and check for water in the base pan.
- Dry thoroughly and then run a short cycle while observing for leaks.
Common leak points:
- Sump-to-tub gasket: look for drips around the sump perimeter.
- Hoses: inspect circulation and drain hoses for cracks or loose clamps.
- Door gasket: check for tears or gaps, especially at the bottom corners.
Corrective actions:
- Replace any leaking gaskets or hoses with KitchenAid-approved parts.
- If you used regular dish soap, flush the unit with a rinse cycle after adding a small amount of cooking oil to break down suds.
