Dishwasher emits a burning smell or shows signs of overheating during operation.

Safety first: Immediately switch off the dishwasher, disconnect power, and do not continue using it until inspected.

• Inspect interior: Open the door and check for plastic items that may have fallen onto the heater or into the sump and melted. Remove any foreign objects.
• Check filters and sump: Clean all filters and the sump to ensure proper water flow and cooling.
• Inspect wiring: Remove the base cover and door panel to inspect wiring harnesses, especially around the heater and pumps, for burnt insulation or loose connectors. Repair or replace damaged wiring.
• Check pumps and heater: If there is evidence of overheating at the circulation pump or heater, test these components and replace if necessary.
• Do not ignore: If you cannot identify the source of the smell, contact a qualified technician. Continued use may be unsafe.
