Possible Causes

Moisture inside motor housing from internal leak, Damaged power cord insulation, Shorted motor windings, Pinched wire at mounting or junction box

How to Fix / Troubleshooting

Safety First: Do not repeatedly reset a tripping GFCI or breaker. Turn OFF power and unplug the disposal if possible.

  • Inspect for leaks: Check for water dripping from the bottom or sides of the Waste Maid unit. Any internal leak can cause ground faults.
  • Check the power cord: Look for cuts, abrasions, or crushed sections. Replace the cord if damaged.
  • Dry the area: If there has been a recent leak, allow the area and unit to dry completely for 24 hours, then test again.
  • Test on a known-good circuit: If corded, temporarily plug the disposal into another GFCI-protected outlet (using a safe extension only if necessary) to rule out a bad GFCI device.
  • Replace if fault persists: Persistent tripping indicates internal electrical damage. Replace the Waste Maid disposal; internal motor and wiring repairs are not recommended.
