Humming, jammed or stuck: first steps
When a unit hums but will not turn, it is almost always jammed. Never put a hand inside.
- Switch off the power. Turn the switch off and, to be safe, unplug the unit or turn off its breaker.
- Use the hex socket. Most disposals have a hex socket in the bottom. A hex key worked back and forth frees the flywheel.
- Press the reset button. A red reset button on the bottom pops out when the motor overheats. Press it once the unit has cooled.
- Run cold water and test. Power back on, water running, and flip the switch. If it hums again, call.
One that stays jammed, trips the breaker or smells of burning has a motor or seal problem and needs a plumber.
Leaking disposals: where the water comes from
Leaking is the most common reason to replace a disposal, and the location of the leak decides whether it can be fixed.
Leaks that can be fixed
A loose drain flange, a worn sink gasket or a leaking connection to the dishwasher or the trap. These are tightened or replaced, and the disposal stays.
Leaks that mean replacement
Water from the body of the unit or from the bottom seal means the housing or the seal has failed. A disposal that leaks from the body cannot be repaired.

Clogs and backups at the kitchen sink
A clogged or backed-up kitchen sink that fills the second basin when the disposal runs points to a blockage past the disposal, in the trap or the branch line. The disposal grinds waste into smaller pieces but does not carry it away, so a clog downstream returns no matter how often the unit is reset. A plumber tells the two problems apart by running water with the disposal off and watching which basin fills. Persistent slow draining at the kitchen sink often has grease coating the branch line, which only a cable or jet removes. Fibrous scraps, eggshell and coffee grounds settle in a trap and add to it over time.
Grease, starchy food and fibrous scraps such as celery or corn husks are the usual culprits. On a septic system, solids and grease add to the load on the tank, so go easy. Persistent blockage is a drain problem and a plumber can clear it. The drain cleaning page explains how.

Dishwasher connection and drain
The dishwasher drain ties into the disposal or the trap, and it is a frequent source of confusion.
| Symptom | Likely cause | What to check |
|---|---|---|
| Dishwasher water in the sink | Knockout plug not removed on a new disposal | Remove the plug in the inlet |
| Dishwasher will not drain | Blocked inlet or a missing air gap | Clear the inlet and the hose |
| Gurgling when the dishwasher runs | Partial clog or a venting issue | Clear the branch line |
A new disposal installed without knocking out the plug blocks the dishwasher drain. It is a short fix, and a common one.

Installing or replacing a disposal
A new unit is sized to the household: a half horsepower suits light use, and larger motors handle heavier loads. Installing or replacing a disposal means disconnecting the old one, setting a new mounting ring and flange, connecting the drain and dishwasher line and wiring or plugging in the power.
A plumber checks the trap and the drain at the same time. Replacing a unit on top of a slow drain only repeats the problem. The wiring is checked as well: a disposal runs on its own switch, and a cord or hardwire connection must be sound, dry and protected. The old unit is removed and hauled away, and the cabinet below is wiped dry so a slow leak does not hide behind a new mounting ring. Once installed, the unit runs with water for a minute while the plumber watches every joint.

Garbage disposal questions answered
Do I need a plumber for garbage disposal repair?
A jam can sometimes be cleared at home with the hex key and the reset button. Leaks, electrical trouble and repeated jams call for a plumber.
Why is my garbage disposal leaking?
Leaks come from the sink flange, the drain or dishwasher connection or the body of the unit. The location tells whether it can be fixed or whether the unit needs replacing.
What does a garbage disposal cost to install?
The price depends on the unit, the electrical connection and the condition of the drain. A written quote after a look under the sink is the dependable figure.
Why is my garbage disposal humming and not spinning?
The flywheel is jammed or the motor is overloaded. Turn off the power, loosen it with the hex key and press the reset button. If it hums again, the motor needs attention.
Sink problems that overlap
A sink that stays slow after the disposal works is a drain cleaning matter. Leaks in the supply lines under the sink go to faucet, toilet and fixture repair.
