Possible Causes

Failed lower motor shaft seal, Cracked disposal housing, Corroded internal components

How to Fix / Troubleshooting

Safety First: Turn OFF power at the breaker and unplug the disposal if possible. Place a pan or towels under the unit to catch water.

Step-by-step:

  • 1. Confirm leak source: Dry the outside of the KitchenAid disposal and run water without operating the unit. If water drips from the bottom center or motor housing, the internal seal is compromised.
  • 2. Check external connections: Verify that the discharge elbow and dishwasher inlet hose are not the source of the leak. Tighten clamps and screws as needed.
  • 3. Do not open housing: The motor housing and internal seals are not user-serviceable. Attempting to open them can create electrical hazards.
  • 4. Protect cabinet: Place a tray or absorbent pads under the unit to protect the cabinet until replacement.
  • 5. Plan replacement: Select a compatible KitchenAid disposal model and prepare for removal and installation.

When to call a technician: Internal leaks require full unit replacement; a professional can remove the old disposal, inspect the sink flange, and install the new unit safely.
