Quick Answer:
If the reset button won’t stay on, most often the disposal is still jammed or the motor has overheated. Power it off, clear any obstruction safely, then press the reset only after the jam is cleared. Run a steady stream of water and test with a short, controlled burst to confirm it stays on.
Why This Happens
- Mechanical jam: A foreign object or a piece of dishware can stop the blades, causing the overload switch to trip.
- Overheated motor: Continuous attempts to run a jammed unit can make the motor overheat and shut off until it cools.
- Electrical or wiring problem: A loose connection or faulty switch can cause repeated trips.
- Appliance interactions: If your dishwasher is connected to the disposal and trips occur when the dishwasher runs, the issue may be in the shared drain or wiring — see Disposal stops when dishwasher runs.
Step-by-Step What to Do
1. Cut power first
Unplug the disposal or switch the circuit breaker off. Never try to clear a jam while the unit has power.
2. Inspect and clear the jam
- Use a flashlight to look down the drain.
- Use long pliers or tongs to remove visible objects. A wooden spoon handle can be used to nudge debris free—never put your hand inside.
- If your model has a crank hole in the bottom, use the appropriate hex key to manually turn the motor to free the jam.
3. Reset, run water, and test
Press reset only after clearing any jam; then run water and test for a short, controlled burst. Keep the water running during the test so debris flushes away and the unit doesn’t overheat. If it trips again immediately, stop and move to troubleshooting.
4. If it trips again, do basic checks
- Listen for unusual sounds (a faint hum without turning may indicate a motor problem).
- Check for a burning smell or smoke—turn power off and call a pro if present.
- Confirm the dishwasher drain hose connection is correct if trips align with dishwasher cycles; related guidance: Disposal motor hums only.
What Not to Do
- Do not spam the reset button without clearing the cause of the trip.
- Do not stick your hand into the disposal, even if it seems off—power could be restored accidentally.
- Do not pour flammable liquids or use blunt force to try to free the unit.
When to Call a Professional
- It keeps tripping after you’ve cleared jams and followed the reset/test step.
- You smell burning or see smoke when the unit is powered.
- The motor hums but the blades don’t turn and basic clearing doesn’t help.
- There are repeated trips tied to other appliances or visible wiring problems.
Safety Notes
- Always disconnect power before working on the disposal.
- Use tools (pliers, hex key) rather than hands to remove objects.
- Wear eye protection if there’s a chance debris could eject during testing.
- Avoid water on switches or exposed wiring; keep the area dry while working on electrical components.
Common Homeowner Questions
- Why does the reset trip right away? Usually because the blades are still jammed or the motor is overheated; clear obstructions and let the motor cool before trying again.
- Can I force the blades to move by hand? No—never put your hand inside. Use the proper hex key or tools from the bottom of the unit.
- Is it okay to run the dishwasher if the disposal is acting up? Not until you confirm the disposal is clear; a shared drain or jam can cause both appliances to fail.
