Possible Causes

Foreign object jammed between turntable and grind ring, Jammed impeller lugs, Seized motor shaft, Worn or damaged bearings in Waste Maid motor

How to Fix / Troubleshooting

Safety First: Turn OFF the wall switch and shut OFF the circuit breaker. Never put your hand inside the disposal while it is connected to power.

  • Use the supplied jam-buster wrench: On the bottom of most Waste Maid disposals there is a hex socket in the center of the motor shaft. Insert the Waste Maid jam-buster (Allen) wrench and rotate back and forth to free the jam.
  • Remove foreign objects: With power OFF, use tongs or pliers from the sink opening to remove bones, utensils, or other debris. Do not use your fingers.
  • Manually rotate the turntable: After loosening with the wrench, use a wooden spoon handle from the top to gently push the impeller lugs and confirm the plate spins freely.
  • Reset and test: Press the red reset button on the bottom of the unit, restore power at the breaker, then briefly turn ON the switch to test.
  • If still humming and locked: The motor shaft or bearings may be seized. At this point, replacement of the disposal is usually more economical than motor repair.
