Washer-dryer emits a burning smell during wash or dry cycles

Safety first: Immediately stop the machine, unplug it, and do not use it again until the cause is identified. Risk of fire.

• Inspect drum and seal: Look for plastic items or clothing trapped against the heater or seal.
• Check lint buildup: Access the dryer heater and air ducts and remove any lint accumulation.
• Inspect belt and pulleys: Look for rubber dust or melted belt material. Replace a damaged belt and realign pulleys.
• Check wiring: Examine wiring near the heater, motor, and control board for signs of overheating or melting. Replace damaged harnesses.
• Professional evaluation: If the source of the smell is not obvious, have a qualified technician inspect the appliance before further use.
