Common Symptoms & Causes
The following symptoms indicate your InSinkErator Evolution Essential XTR is experiencing a MultiGrind Technology jam.
🔨 Pro Tip from Dave
One thing most homeowners miss on the Evolution Essential XTR is that the MultiGrind system uses two grinding stages, so a jam can actually be lodged in the upper grind ring (part #12664-00) rather than the flywheel — meaning the standard ¼-inch hex wrench trick at the bottom won’t fully free it. Always run the unit briefly after the initial clearing, then check again before assuming it’s fixed, because that second grind stage can re-jam immediately if debris wasn’t fully expelled.
- The disposal unit hums loudly but the grinding plate does not spin
- The reset button on the bottom of the unit trips repeatedly after restarting
- Hard food waste such as bones or fruit pits remains unground after a full cycle
- The unit shuts off automatically mid-cycle without completing the grind
These issues are typically caused by debris lodged between the grinding components, a worn or seized grinding plate, or accumulated buildup overwhelming the multi-stage grind system over time.

How Much Does This Repair Cost?
Fixing a MultiGrind Technology jam on your InSinkErator Evolution Essential XTR yourself typically costs between $0–$20, usually just a replacement hex wrench or reset button tool. A professional service call for the same issue runs $150–$300 once labor and fees are included. Tackling this repair DIY-style can save you well over $100.
