Freeing a Jammed Disposer

Each InSinkErator disposer is shipped with a self-service wrench. The wrench is silver colored, and shaped like a little crank, about four inches long. If you can not find the service wrench, you can use a standard 1/4 inch Allen wrench, or click here to have one sent to you by mail.

Make certain that the disposer's switch is in the off position.

If the sink is full of water, wait for it to drain, or bail the water out using a bucket or pot.

Insert the wrench into the hole at the bottom of the disposer. The hole is located under the sink, at bottom of the disposer, dead center, facing the floor. Use the wrench like a crank.

Wrench and ResetWork the wrench back and forth in both directions. If the wrench will not turn easily, it is OK to use some force. The wrench is designed to bend before any damage is done to the disposer.

Continue working with the wrench until it turns freely in complete circles in both directions.

Check the overload protector. The overload protector is located under the sink, on the bottom of the disposer, facing the floor. It is a small square red button. Wrench and ResetIf the overload protector has tripped, you will see the red button dropped down about a quarter of an inch (5mm). Gently press the red button. If it does not stay up, wait ten minutes and try again.

Check inside the disposer's grinding chamber. Look down into the disposer using a flashlight. Do not place your hand into the disposer. Pay special attention to the area around the outer edge of the disposer's shredding disk where you see the little teeth. If you see anything in the disposer, remove it using tongs or pliers.  

Turn on the water, then the disposer. The disposer should now run. If it jams again, use the wrench again. You may need to repeat the process several times.

If the disposer continues to jam, you may need service. If the problem with your disposer is due to defects in materials or workmanship, InSinkErator will pay to have an authorized service center service the disposer in your home at no charge to you. If the disposer is jammed on a non-food, foreign object, you will be responsible for the cost of service.
