Garbage Disposal Troubleshooting

Most disposal problems are jams or a tripped overload — both are fixable without a plumber.

It hums but doesn't spin (jammed)

1. Turn the switch OFF and unplug or flip the breaker.
2. Use the hex wrench that came with the unit — insert it into the bottom socket and rock it back and forth to free the jam.
3. Remove the obstruction with tongs (never your hand).
4. Press the red reset button on the bottom of the unit.
5. Restore power and test with cold water running.

It does nothing (tripped)

• Press the reset button on the bottom of the unit.
• Check the breaker in your panel.
• Check the outlet (GFCI) — press Test then Reset.

Bad smell

• Grind ice cubes and citrus peels to clean the blades.
• Pour a baking soda + vinegar mix, let sit, then flush with hot water.
• Keep the rubber splash guard wiped clean.

What never to put down a disposal

• Grease or oil — solidifies and clogs
• Fibrous foods — celery, onion skins, corn husks
• Starchy foods — pasta, rice, potato peels (swell and clog)
• Bones, fruit pits, coffee grounds
• Non-food items, paint, cleaning chemicals

When to call a pro

Persistent leaks from the bottom, a motor that spins but doesn't drain, or repeated resets — the unit may need replacement (typical life is 8–15 years).
