Garbage disposal does not respond; no sound; GFCI outlet trips immediately when disposal is switched on.

Safety First: Turn OFF the wall switch and circuit breaker. Do not repeatedly reset a tripping GFCI without inspection.

Step-by-step:

• 1. Inspect the power cord and plug: Unplug the KitchenAid disposal and inspect the cord for cuts, burns, or crushed sections. Replace the cord set if damaged.
• 2. Check for leaks: Look for water dripping from the bottom of the disposal or around the sink flange that could be entering the motor housing. If present, do not use the unit until leaks are repaired.
• 3. Dry the area: If minor moisture is present externally, dry the outside of the unit and cabinet. Do not attempt to open the sealed motor housing.
• 4. Test GFCI: With the disposal unplugged, reset the GFCI. If it holds, plug in a different appliance to confirm the outlet is good.
• 5. Reconnect and test: Plug the disposal back in, restore power, and test briefly. If the GFCI trips again only when the disposal is used, the motor is likely shorted.

When to call a technician: A disposal with internal ground faults or water inside the motor housing is not serviceable; replacement of the entire unit is recommended.
