Leveling the Appliance
Use a level to ensure the washing machine is perfectly balanced. Adjust the leveling feet by turning them clockwise or counter-clockwise until the machine is stable and level. An unbalanced machine can cause excessive vibration and noise.
Water Supply Connection
Connect the hot and cold water inlet hoses to the corresponding hot and cold water faucets. Ensure connections are tight to prevent leaks. Use new hoses provided with the washer to prevent water leakage or overflow.

Key Technologies
- 6 Motion DD: This technology combines up to six different wash motions (stepping, scrubbing, filtration, tumbling, rolling, swing) to provide optimized washing for various fabric types, reducing wear and tear.
- Inverter Direct Drive Motor: The motor is directly attached to the drum, reducing noise and vibration while increasing durability and energy efficiency.
- TurboDrum: The drum and pulsator rotate in opposite directions, creating a powerful water flow that effectively removes tough dirt and stains.
- 4-Way Agitator: Enhances washing performance by creating multi-directional water currents for thorough cleaning.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your washing machine.
Cleaning the Exterior
