Dishwasher emits a burning smell during operation.

Safety: Immediately stop the dishwasher, unplug it, and do not continue using it until the cause is found.

• Inspect interior: Once cooled, check the bottom of the tub for melted plastic or items that may have contacted the heater.
• Check wiring: Remove the base and control panel to inspect wiring for signs of burning or melted insulation.
• Smell localization: Try to localize the smell source (base, door, control panel) to identify the overheating component.
• Replace faulty parts: Replace any burnt connectors, wiring, or components such as the circulation pump or heater. If the control board shows burn marks, replace it. Due to fire risk, this repair is best handled by a qualified technician.
