To ensure no glass is trapped under the blades, you need to manually rotate them. Locate the Allen wrench that typically comes with the garbage disposal; it's often stored on the unit or nearby pipes. Insert the wrench into the hexagonal socket on the very bottom of the disposal motor housing. Turn the wrench back and forth to move the internal grinding plate, which will dislodge any trapped debris.

Goal: Dislodge Trapped Debris

  • If you can't find the original tool, a standard 1/4-inch Allen wrench will work for most models.

FAQs

Why is disconnecting the power at the circuit breaker the very first step?

Disconnecting the power is crucial for safety to prevent accidental activation of the disposal while your hands or tools are inside or near the unit. It eliminates the risk of severe injury from the spinning impellers.

What if I don't have a special garbage disposal wrench?

If you don't have a specialized garbage disposal wrench, a 1/4-inch Allen wrench can typically be used. This common tool fits into the turning port at the bottom of most garbage disposal units, allowing you to manually rotate the impeller.

After manually rotating the impeller, my disposal just hums but doesn't grind. What does this mean?

A humming sound indicates the motor is receiving power but cannot spin the impellers. This often means the motor is seized, damaged, or burned out. In most cases, if clearing the jam doesn't resolve this, the entire unit may need to be replaced.

I'm having trouble finding the turning port or rotating the impeller. Any tips?

The turning port is usually a hexagonal hole located directly in the center of the bottom of the garbage disposal unit. Use your flashlight to clearly see this port. You may need to apply firm, consistent back-and-forth pressure to free a stubborn jam.
