How to Fix / Troubleshooting
Safety first: Immediately stop the cycle, unplug the washer, and do not continue to operate until the source is identified.
- Step 1 – Visual inspection: Remove the rear panel and inspect the belt, motor, and wiring for signs of melting, discoloration, or smoke residue.
- Step 2 – Check belt tension: If the belt is loose and shows signs of burning (rubber dust, smell), replace it and ensure correct routing.
- Step 3 – Inspect pump and drum: Check for objects stuck between drum and tub or in the pump that could overload the motor.
- Step 4 – Motor and PCB: If the smell originates from the motor or control board, discontinue use and arrange professional service, as continued operation may pose a fire risk.
