Common Symptoms & Causes

The following symptoms typically indicate your InSinkErator Evolution Compact needs an anti-jam mechanism reset.

  • The disposal hums but the grinding plate does not spin when activated
  • The reset button on the bottom of the unit has visibly popped out
  • The disposal suddenly stops mid-cycle and will not restart
  • The unit makes a brief buzzing sound then goes completely silent

These issues are most commonly caused by a hard food item or debris jamming the grinding plate, triggering the built-in thermal overload protector and forcing an automatic shutoff.

Frequently Asked Questions

How do I know if my InSinkErator Evolution Compact needs an anti-jam reset?

If your unit hums but won’t spin or has completely stopped working, the anti-jam mechanism has likely tripped. This is a built-in safety feature that activates when the grinding chamber becomes obstructed.

Where is the reset button on the InSinkErator Evolution Compact?

The red reset button is located on the bottom of the unit beneath your sink. Press it firmly until you feel it click into place.

What should I do if the reset button keeps popping out?

A repeatedly tripping reset button usually means a jam is still present in the grinding chamber. Use the included hex wrench in the center bottom port to manually rotate the grinding plate and clear the obstruction before resetting again.
