If your garbage disposal stops working, start with the reset button on the bottom of the unit. This fixes most disposal problems in under a minute. If that doesn’t work, check for a jam, verify the power connection, and inspect the circuit breaker. This troubleshooting guide from Staggs Plumbing covers the 5 most common causes and what you can do before calling a plumber.
Quick Reference: Disposal Problems and Solutions
| Symptom | Likely Cause | DIY or Pro? |
|---|---|---|
| Completely dead (no sound) | Tripped reset or breaker | DIY |
| Humming but not spinning | Jammed flywheel | DIY |
| Leaking from bottom | Internal seal failure | Call Pro |
| Drains slowly | Clog in drain line | DIY first |
| Trips breaker repeatedly | Electrical or motor issue | Call Pro |
5 Common Causes (And How to Fix Them)
1. Tripped Reset Button
Look under your disposal unit for a small red or black button. Press it firmly until you hear a click. Wait 15 seconds, then test the disposal.
2. Jammed Flywheel
If your disposal hums but doesn’t spin, something is stuck in the grinding chamber.
- Turn off the disposal and unplug it (or turn off the breaker).
- Insert an Allen wrench (1/4 inch) into the hex socket on the bottom of the unit.
- Work the wrench back and forth to free the flywheel.
- Remove any debris with tongs or pliers (never your hand).
- Restore power and test.
3. Tripped Circuit Breaker
Check your electrical panel for a tripped breaker. Flip it fully off, then back on.
4. Clogged Drain Line
If your disposal runs but water pools in the sink, the drain trap or pipe may be blocked.
5. Failed Motor or Internal Seals
A disposal that leaks from the bottom or won’t run despite power and no jam likely has internal damage. Replacement is usually more cost-effective than repair.
When to Call a Plumber

- Water leaks from the bottom of the unit
