How to Fix Anti-Jam Mechanism Reset on InSinkErator Evolution Compact

5 min read

I’ve worked on dozens of InSinkErator Evolution Compact units over the years, and the anti-jam mechanism reset is hands-down the most common service call I get for this model. About 80% of the time, the fix is simply pressing the red reset button on the unit’s bottom and clearing the jam with the included hex wrench. It’s a satisfying repair because most homeowners can handle it themselves.

🔨 Pro Tip from Dave

On the Evolution Compact, don’t overlook the 1/4-inch Allen wrench port on the bottom center of the unit — a common mistake I see is homeowners pressing the reset button (part of the overload protector assembly) without first manually rotating the grinding plate counterclockwise using a hex key to break the actual jam loose. If you skip that step, the unit will trip the overload again within seconds. The overload protector for this model is part number 12700-ISE if it needs replacing.

  • 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.

How Much Does This Repair Cost?

Resetting the anti-jam mechanism on an InSinkErator Evolution Compact is typically free or costs under $10 if you need a replacement hex wrench. A professional service call for this repair usually runs $150–$300 including labor. Tackling this yourself can save you over $140, making DIY the smart choice.

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.

The Hex Wrench That Actually Clears Evolution Compact Jams Without Forcing It

After you hit that red reset button, you need the right tool to manually rotate the impeller and break up whatever’s stuck in the chamber. The InSinkErator WRN-00 Jam-Buster Wrench is designed specifically for this model, and using the wrong size wrench is how you strip the socket or crack plastic fittings.

What works

  • Fits the bottom socket on the Evolution Compact without any guessing—it’s engineered for this exact model, so you get solid contact and leverage.
  • The wrench is short and stubby, which means you can work it in tight under-sink spaces without banging your knuckles on the pipes and cabinet walls.
  • Turning the impeller clockwise with the right tool takes maybe 30 seconds once you’ve cleared the debris—you feel the resistance drop when the jam breaks free.

What doesn’t

  • If you lose it (and people do), finding a replacement takes ordering online—it’s not a standard hex key you can grab from your toolbox.
  • For other InSinkErator models like the Badger or Evolution series, the socket size can vary, so don’t assume this wrench works on every disposal in your house.

I learned the hard way that using a generic Allen wrench or socket that’s just close enough to the right size will strip the socket and leave you unable to rotate the impeller at all. Grab the OEM wrench first. InSinkErator WRN-00 Jam-Buster Wrench,Silver
