Dishwasher emits a burning or electrical smell during operation.

Safety first: Immediately turn off the dishwasher, disconnect power at the breaker, and do not use the appliance until inspected.

• Visual inspection: Remove the toe-kick and side panels to inspect wiring, pump, and heater connections for signs of burning, melting, or discoloration.
• Check pump and heater terminals: Tighten any loose spade connectors and replace any that show heat damage.
• Control board: Remove the inner door panel and inspect the control board for burned components or a burnt smell. Replace the board if damage is evident.
• Professional evaluation: Because burning smells indicate a potential fire hazard, have a qualified technician perform a full safety check before returning the dishwasher to service.

Do not ignore burning odors; they require immediate attention.
