It’s jammed. Don’t stick anything in from above.
It hummed, then stopped. The sink is holding water. Clear it from below. Do not fish from the drain with a knife, a spoon, or your hand.
Four steps
- Kill power. Wall switch off. If you go under the sink, kill the breaker too. Confirm the unit cannot start.
- Flashlight and tongs, not fingers. Look down the drain. Lift out bone, glass, or silverware with tongs. Never put your hand in the chamber.
- 1/4″ hex key in the bottom socket. Under the unit, find the hex socket in the center. Work the key back and forth until the plate turns freely both ways.
- Red reset, cold water, switch. Press the red reset on the bottom. Run a steady stream of cold water. Turn the wall switch on.
Burnt wiring or a melted cord: stop. That is not a jam. Do not hit reset. Leave the breaker off and get a plumber or an electrician.
If it is still stuck
Another twist of the key will not save it. Treat it as a repair-or-replace decision.
Still stuck — garbage disposal repair
Third jam this month — look at a new unit
