Possible Causes

Water intrusion into motor housing, Damaged power cord insulation, Shorted motor windings, Pinched wire at mounting bracket

How to Fix / Troubleshooting

Safety first: Leave the breaker off and unplug the disposal. Do not repeatedly reset a breaker that trips immediately.

  • Inspect for leaks: Check around the Whirlpool disposal body, sink flange, and discharge elbow for signs of water leaks that could reach the wiring or motor.
  • Check power cord: Examine the cord for cuts, abrasions, or crushed sections. Replace the Whirlpool power cord kit if damaged.
  • Inspect wiring compartment: Remove the wiring cover on the disposal base and look for burned wires or loose connections. Repair or replace as needed.
  • Dry and test: If moisture is present, dry thoroughly and correct the leak before restoring power. If the breaker still trips immediately when the disposal is switched on, the motor is likely shorted and the disposal should be replaced.
