How to Fix / Troubleshooting
Safety first: Disconnect power immediately. Do not operate a leaking disposal due to shock risk.
- Step 1 – Confirm leak location: Dry the exterior, then run water without operating the disposal. If no leak appears, briefly run the unit and watch for water emerging from the bottom or motor area.
- Step 2 – Inspect for external plumbing leaks: Ensure the leak is not from above (sink flange or side connections) running down the housing.
- Step 3 – Assess housing condition: If water clearly comes from the lower housing seams or motor area, the internal seal or chamber is compromised.
- Step 4 – Replace unit: Internal leaks are not serviceable on compact Teka disposals. Remove and replace the complete unit, ensuring all seals and electrical connections are correctly installed.
