Disposal turns on but immediately trips the circuit breaker or GFCI; may show six internal LED flashes on some models before losing power.

Safety First: This is an electrical safety issue. Turn OFF the breaker and leave it OFF while inspecting. Do not repeatedly reset a tripping breaker.

• Step 1 – Inspect for visible damage: Check the underside of the AmazonCommercial unit for cracks, burn marks, or water leaks onto the motor housing.
• Step 2 – Check the power cord and junction box: Look for cuts, crushed sections, or melted insulation on the cord or internal wires. Tighten loose wire nuts in the wiring compartment with power OFF.
• Step 3 – Dry any moisture: If there is evidence of a leak from the sink flange or plumbing onto the motor, correct the leak first and allow the unit to dry completely for 24 hours before testing.
• Step 4 – Test on a known-good circuit: If possible, plug the unit into a different GFCI-protected outlet using a proper cord kit to rule out a bad breaker.
• If breaker still trips: The motor windings or internal wiring are likely shorted. Replacement of the disposal is recommended; internal motor repairs are not cost-effective for this class of unit.
