Disposal runs but makes a loud electrical buzzing or burning smell; some smart controls may show E6 indicating motor fault.

Safety first: Immediately turn OFF the wall switch and shut OFF the circuit breaker if you smell burning or see smoke. Do not attempt to restart the unit.

• Inspect for visible damage: With power OFF, look under the sink for scorch marks, melted insulation, or discoloration on the bottom of the American Standard disposal.
• Check for leaks: Inspect around the sink flange and dishwasher inlet for water leaks that may have dripped onto the motor housing.
• Do not open motor: The motor on American Standard disposals is factory sealed and not user-serviceable.
• Replace unit: If burning smell or E6 motor fault occurs, the safe and practical repair is to replace the entire disposal. Continuing to use a failing motor is a fire hazard.
• Correct leak sources: If moisture caused the failure, repair any sink flange or hose leaks before installing the new unit.
