Stop and turn off the power first

A stuck garbage disposal is almost always fixable at home, but the first step is the most important: turn off the power. Flip the wall switch to off, then go to your circuit breaker and switch off the breaker that controls the disposal. Do not skip this step. A disposal can start suddenly if someone flips the switch while your hand is near the blades, and that injury happens fast enough that you cannot pull away.

Once the power is off, wait a full minute. Some disposals have a reset button on the bottom of the unit (a small red or black button). If yours does, you can press it now, but only after you are certain the power is off. The reset button trips when the motor overheats or jams, and pressing it while power is on does nothing.

Key Takeaways

  • Always turn off the power at the wall switch and circuit breaker before touching a stuck disposal, because the blades can start without warning.
  • Most stuck disposals are caused by food, bones, or fibrous material wrapped around the impeller blades, which you can remove with tongs or a wooden spoon.
  • Never put your hand down the drain; use tools to fish out the blockage, and wear gloves to protect against sharp edges.
  • If the disposal hums but does not spin, the motor is running but the blades are jammed; if it makes no sound at all, check the reset button and the circuit breaker.
  • A disposal that leaks from the bottom or sides usually needs a professional plumber, because the seals inside have failed.

Remove visible blockage with tongs or a wooden spoon

Look down into the drain opening with a flashlight. If you can see food, bones, or fibrous material (like celery strings or corn husks) caught around the blades, you can often remove it yourself. Use tongs or a wooden spoon — never your fingers or a metal tool. Metal can damage the blades or spark against them.

Grab the blockage and pull it straight up and out. If it is wrapped around the impeller (the spinning part in the center), you may need to wiggle it gently to loosen it. Fibrous material is the most common culprit; it wraps around the blades and stops them from turning. Once you remove the blockage, run cold water down the drain for 30 seconds to flush away smaller debris.

Use the hex wrench to manually turn the blades

If you cannot see the blockage or it will not come loose, the disposal may have a hex socket on the bottom of the unit. This socket lets you manually turn the impeller blades to break up the jam. Most disposals come with a hex wrench (also called an Allen wrench) that fits this socket; check your manual or the bottom of the unit to see if one is stored there.

Insert the wrench into the socket and turn it back and forth — not in one direction only. Turn it a quarter turn, then back, then forward again. This rocking motion breaks up the material clogging the blades. After 10 to 15 rocks, remove the wrench and try running water down the drain again. If the blades still will not turn, repeat the process.

If your disposal does not have a hex socket, you cannot manually turn the blades, and you will need to move to the next step or call a plumber.

Check the reset button and circuit breaker

If the disposal makes no sound at all when you flip the switch — no humming, no grinding, nothing — the problem is electrical, not mechanical. First, press the reset button on the bottom of the unit again (with the power still off). Then turn the power back on at the circuit breaker and try the switch.

If the disposal still does not respond, go back to the circuit breaker and check whether the breaker has tripped to the middle position. If it has, flip it all the way off, then back on. This resets the breaker. Try the disposal again. If the breaker trips when ready when you turn on the disposal, the motor has an internal fault and the unit needs to be replaced.

Run the disposal correctly to prevent future jams

Once your disposal is working again, use it the right way to avoid another jam. Always run cold water while the disposal is on — start the water, turn on the disposal, and let it run for a few seconds after you stop feeding it food. Cold water helps solidify grease so it breaks apart instead of coating the blades.

Feed food slowly and in small amounts. Do not dump a full plate of scraps in at once. Avoid putting bones, fibrous vegetables (celery, corn husks, onion skins), grease, or starchy foods (pasta, rice) down the disposal. These are the materials that jam disposals most often. If you have a lot of scraps, compost them or throw them in the trash instead.

When to call a plumber

If the disposal hums but the blades do not turn, and the hex wrench does not free them, the motor is running but something inside is broken. This usually means the coupling (the part that connects the motor to the blades) has failed, or the blades themselves are bent. Either way, the disposal needs to be replaced.

If the disposal leaks from the bottom or the sides of the unit, the seals inside have failed. This is not a jam — it is a structural problem that requires a plumber to remove and replace the unit. Do not try to fix this yourself; water will continue to leak into the cabinet below the sink.

If you have tried the steps above and the disposal is still stuck, or if you are not comfortable working with the unit, a plumber can remove the blockage and diagnose any deeper problems. The cost is usually between $150 and $300 for a service call and repair.

Frequently Asked Questions

Can I use a plunger on a garbage disposal?

Yes, but only after the power is off and you have removed any visible blockage. Fill the sink with a few inches of water, place the plunger over the drain, and plunge firmly 10 to 15 times. The suction can dislodge material stuck further down the drain. If this does not work, try the hex wrench method instead.

What if the disposal is leaking from the bottom?

A leak from the bottom of the unit means the seals have failed and the disposal cannot be repaired. You will need to replace it. Turn off the power, disconnect the drain lines, and unbolt the unit from the sink. A plumber can do this in about an hour, or you can do it yourself if you are comfortable with basic plumbing.

Is it safe to put my hand down the drain to feel for the blockage?

No. Even with the power off, the blades are sharp and can cut your hand. Always use tongs, a wooden spoon, or a flashlight to see what is stuck. If you cannot reach it with tools, a plumber has a drain snake and can pull it out safely.

How long should a garbage disposal last?

Most disposals last 8 to 15 years depending on how often you use them and what you put down the drain. If yours is more than 10 years old and jams frequently, replacing it may be cheaper than repeated repairs. A new disposal costs $150 to $500 plus installation.
