A disposal that hums but won't spin is usually jammed and can often be freed. One that leaks from the body, or trips its reset button repeatedly, generally needs to be replaced.

    Make it safe

Most disposal calls fall into three groups: jammed, leaking or dead. Jams are the easy ones. Leaks depend on where the water comes from — a loose drain connection is a repair, a leak from the bottom of the grinding chamber is not.

When replacement makes sense, match horsepower to how you actually cook and check that the dishwasher drain connection and the outlet are right, so the new unit doesn't inherit the old one's problems.

Garbage Disposal Repair: common questions

Why does my garbage disposal hum but not work?

The flywheel is jammed, usually by a hard object or fibrous food. With the power off, turn it from underneath with a hex key, remove the obstruction with tongs, then press reset.

How long do garbage disposals last?

Around 8–15 years depending on use and build quality. Leaks from the housing are the usual sign it's done.

What should never go down a garbage disposal?

Grease and oil, coffee grounds, eggshells, fibrous vegetables like celery and corn husks, pasta and rice in quantity, bones, and anything non-food. These jam the unit or clog the drain beyond it.

Why does my garbage disposal smell?

Food residue trapped under the splash guard and on the grinding chamber causes most odors. Grinding ice and citrus peels and cleaning the splash guard usually helps; persistent odor can mean a partial drain clog.

How do I reset a garbage disposal?

Turn the switch off, wait a minute for the motor to cool, then press the red reset button on the bottom of the unit and try again. If it hums without spinning, the flywheel is jammed.

Is it safe to reset a garbage disposal myself?

Yes, with the power off: press the red reset button on the bottom, and if it hums but won't turn, free the jam with the hex key socket under the unit. Never put your hand in the disposal.

Why is my garbage disposal leaking from the bottom?

A leak from the body of the unit usually means internal seals have failed, which typically means replacement rather than repair.
