Possible Causes
Shorted motor windings, Water ingress into wiring compartment, Overloaded circuit shared with other appliances, Damaged power cord
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker or RCD that trips. Isolate power and investigate.
- Step 1 – Check for leaks: Inspect around the disposal for water leaks that may be reaching the wiring or motor housing.
- Step 2 – Inspect cord and plug: Look for cuts, crushed sections, or burn marks on the power cord. Replace if damaged.
- Step 3 – Reduce circuit load: Ensure the disposal is not sharing a circuit with high‑load appliances (dishwasher, oven). If it is, consult an electrician about dedicated wiring.
- Step 4 – Test with empty chamber: After confirming no leaks, run the disposal briefly with water only. If the breaker trips immediately, the motor is likely shorted.
- Step 5 – Call a professional: Ground faults and internal shorts require electrical testing and usually replacement of the unit.
