Do not overload the drum; leave space for laundry to move. Use detergent in an amount suitable for the model and water hardness because excess foam can interfere with the pump and level control.
After washing, leave the door and dispenser open for a while. Wipe water and small objects from the seal and inspect the drain filter according to the manufacturer’s instructions.
Keep the appliance on a solid level floor. New noise, odour, leaks or unusually long cycles should be checked early before another component is damaged.
