Possible Causes

Overloading with hard food waste, Running without sufficient water flow, Partially jammed impellers increasing motor load, Failing motor windings drawing excessive current

How to Fix / Troubleshooting

Safety first: Turn off the wall switch and unplug the disposal or turn off the breaker before inspecting the unit.

  • Allow motor to cool:
    • Wait 10–15 minutes for the internal overload to cool.
    • Press the reset button on the bottom of the Moen disposal until it clicks.
  • Check for partial jams:
    • Use a jam-buster wrench or 1/4" Allen key in the bottom hex socket to rotate the jam plate back and forth.
    • Remove any debris from the grind chamber using tongs (never hands).
  • Use proper operating technique:
    • Always run cold water before, during, and for 15–30 seconds after grinding.
    • Avoid large quantities of fibrous foods (celery, corn husks), starchy pastes (large amounts of potato peels), or non-food items.
  • Monitor load:
    • If the reset trips even with light loads and clear chamber, the motor assembly is likely failing.
    • In that case, replacement of the disposal is recommended.
