Disposal causes a noticeable electrical shock or tingle when touching the sink or nearby metal surfaces during operation.

Safety First: Immediately turn OFF the circuit breaker. Do not touch the disposal or sink until power is off. This is a serious electrical hazard.

• Step 1 – Inspect power cord and plug: Look for cuts, abrasions, or exposed conductors. Replace the cord set if damaged.
• Step 2 – Verify grounding: Ensure the green ground wire is securely connected to the disposal's ground screw and to the house ground in the junction box or outlet.
• Step 3 – Check outlet wiring: Use a receptacle tester to confirm correct hot/neutral/ground configuration. Correct any wiring errors.
• Step 4 – Evaluate internal leakage: If external wiring is correct but shocks persist, the motor insulation may be compromised.
• Do not continue using a disposal that causes shocks. Replace the unit and have a qualified electrician verify the circuit.
