Items to Avoid
- Large bones, corn husks, artichokes, and other fibrous materials.

- Non-food items such as plastic, metal, glass, or paper.
- Harsh chemicals or drain cleaners.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your garbage disposal.
Cleaning Your Disposal
- For Odors: Grind citrus peels (lemon, orange) with cold water to freshen the disposal.
- For Buildup: Grind a tray of ice cubes with cold water to help dislodge food particles and clean the grind chamber.
- Do not use abrasive cleaners or harsh chemicals.
General Tips
- Always use cold water when operating the disposal. Cold water solidifies grease, allowing it to be ground and flushed away.
- Run the disposal regularly, even if you don't have much food waste, to prevent rust and keep components moving.
Troubleshooting
If your disposal is not operating correctly, consult the following common issues and solutions before contacting service.
| Problem | Possible Cause | Solution |
|---|---|---|
| Disposal hums but does not grind. | Jam in the grind chamber. | Turn off power. Insert the hex wrench (provided) into the center hole on the bottom of the disposal and turn it back and forth until the jam is cleared. Remove the object with tongs or pliers. Press the red reset button on the bottom of the disposal. |
| Disposal does not operate at all. | No power, tripped circuit breaker, or tripped reset button. | Check your home's circuit breaker. Press the red reset button on the bottom of the disposal. Ensure the power cord is securely plugged in (if applicable). |
| Leaking from the disposal. | Loose connections, cracked housing, or worn seals. | Check all plumbing connections for tightness. If the housing is cracked or seals are worn, professional service or replacement may be required. |
