Turn off the power before you touch anything inside

The first step is always the same: kill the power. Flip the switch at the wall to OFF, or if your disposal is hardwired, turn off the breaker. Do not rely on the disposal being "off" — you need the power physically disconnected. A disposal can start unexpectedly if someone flips the switch while your hand is near the blades, and that injury happens in a fraction of a second.

Once the power is off, run water down the drain for a few seconds to clear loose debris. Then look into the drain opening with a flashlight. You are looking for what is stuck: a piece of bone, a fruit pit, a bottle cap, a twist-tie, or a chunk of food that did not break down. Write down what you see, because it tells you which removal method to use.

Key Takeaways

  • Always turn off the power at the wall switch or breaker before putting your hand near the disposal blades.
  • Use tongs or pliers to pull out visible objects — never reach in with your fingers, even when the power is off.
  • If the jam is deeper in the drain, use the hex wrench that came with your disposal to manually turn the motor shaft back and forth.
  • Running hot water and dish soap after clearing the jam helps flush out smaller debris and prevents future clogs.
  • If the disposal still will not turn after you clear the visible jam, the motor may be overloaded and needs to cool for 15 minutes before trying again.

Remove visible objects with tongs or pliers

If you can see the object blocking the drain, use needle-nose pliers or kitchen tongs to pull it out. Reach in, grab the object, and pull it straight up and out. This works for bones, pits, caps, and other solid items. Do not use your fingers — even with the power off, the blades are sharp and the drain is tight.

If the object is wedged and will not budge with a gentle pull, do not force it. Forcing can break the object into smaller pieces that fall deeper into the drain, or damage the disposal itself. Instead, move to the next step.

Use the hex wrench to manually turn the motor shaft

Most garbage disposals come with a hex wrench (also called an Allen wrench) that fits into a socket on the bottom of the unit. This wrench lets you manually rotate the motor shaft, which can dislodge a jam without running the motor. Look under your sink for the wrench — it is usually a small L-shaped metal tool, often taped to the side of the disposal or in the original box.

Insert the wrench into the socket at the bottom center of the disposal. Turn it back and forth — not in one direction, but alternating left and right. Turn it a quarter turn, then back, then forward again. Do this 10 to 15 times. You will feel resistance, and that is normal. The goal is to loosen whatever is jamming the blades so it can be removed or flushed out.

After working the wrench, remove it and look into the drain again with your flashlight. Often the jam has shifted enough that you can now pull it out with pliers. If you still see the object, repeat the wrench motion another 10 to 15 times.

Flush the drain with hot water and dish soap

Once you have removed the visible jam, turn the power back on and run hot water down the drain for 30 seconds while squirting a tablespoon of dish soap into the opening. The hot water and soap help flush out smaller food particles and grease that may be stuck to the blades or drain walls. This step also tells you whether the disposal is working again — you should hear it running normally, with no grinding or rattling sounds.

Let the water run for the full 30 seconds, then turn off the disposal and let the water continue for another 10 seconds. This clears the drain line completely.

Reset the overload protection if the motor will not start

If you have cleared the visible jam but the disposal still will not turn on, the overload protection has likely tripped. This is a safety feature that shuts down the motor when it is working too hard. To reset it, turn off the power, wait 15 minutes, then turn the power back on and try again.

If the motor still will not start after 15 minutes, the jam may be deeper in the drain line, or the motor itself may be damaged. At that point, you have two choices: call a plumber, or try the next step if you are comfortable working with plumbing.

Remove the P-trap if the jam is in the drain line below

If the disposal itself is clear but water is not draining, the jam is in the P-trap — the curved pipe under the sink. Place a bucket under the trap to catch water, then use an adjustable wrench to loosen the slip nuts on both ends of the trap. Unscrew them by hand once they are loose, and remove the trap. Look inside with a flashlight — you will usually see a clump of food, hair, or grease.

Use a straightened wire coat hanger or a plumbing snake to push the clog out, or straightforward rinse the trap under a faucet to clear it. Once it is clean, screw the slip nuts back on by hand, then tighten them with the wrench. Turn on the water to check for leaks. If water drips from the nuts, tighten them another quarter turn.

Prevent future jams with these habits

The best jam is the one that never happens. Do not put bones, fruit pits, or fibrous vegetables like celery into the disposal. These items do not break down and cause most jams. Also avoid putting grease or oil down the drain — they solidify as they cool and create clogs deeper in the line.

Run cold water while the disposal is running, and continue running water for 10 seconds after you turn it off. Cold water helps solidify grease so it breaks apart instead of sticking to the pipes. Once a week, run hot water and dish soap through the disposal to clean the blades and drain line.

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 objects. Fill the sink with a few inches of water, place the plunger over the drain, and pump it 10 to 15 times. This can dislodge a jam that is deeper in the drain line. If the plunger does not work after two or three tries, move to the P-trap method.

What if I smell something bad coming from the disposal?

That is usually old food stuck to the blades or drain walls. Run hot water and dish soap through the disposal for 30 seconds, then turn it off and let the water continue for another 10 seconds. If the smell persists, drop a handful of ice cubes into the disposal, turn it on for 5 seconds, then flush with hot water. The ice helps scrub the blades clean.

Is it safe to put my hand in the disposal if the power is off?

The power being off is necessary but not enough. Always use tongs or pliers instead of your fingers. Blades are sharp, the space is tight, and even with the power off, you risk cutting yourself or getting your hand stuck.

How long does it take to clear a jam?

Most jams take 10 to 20 minutes if the object is visible and removable. If you need to use the hex wrench or remove the P-trap, add another 15 to 30 minutes. If the jam is deeper in the drain line or the motor is damaged, you may need to call a plumber.
