How to Fix / Troubleshooting

Safety First: Turn OFF power and do not operate the disposal while it is leaking.

Step-by-step:

1. Identify leak path: Run water without operating the KitchenAid disposal and observe where water emerges around the mounting area.
2. Tighten mounting ring: Rotate the mounting ring clockwise to ensure it is fully locked onto the sink flange.
3. Inspect gasket: If tightening does not stop the leak, remove the disposal from the mounting assembly and inspect the rubber mounting gasket. Replace if cracked or deformed.
4. Reinstall correctly: Reattach the disposal, ensuring the gasket is seated evenly and all three mounting lugs are engaged.
5. Test for leaks: Run water and check again before restoring power.

When to call a technician: If the mounting assembly is corroded or damaged, a full replacement may be needed.

Garbage disposal turns on but water leaks from the top side of the unit where the body meets the mounting assembly.
