■ Anti Crease function

With the alternate rotation of the drum, creasing in the laundry is minimized.

■ More economical by Fuzzy Logic System

FUZZY Logic System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption.

■ Child-Lock

The Child-Lock system has been developed to prevent children from pressing any button (except Power button) to change the programme during operation.

■ Low noise speed control system

By sensing the amount of load and balance, this system automatically distributes load evenly to minimize the spinning noise level.

■ Direct Drive System

The advanced Brushless DC motor rotates the drum directly

without a belt and a pulley.

■ Built-in heater

Internal heater automatically heats the water to the best

temperature on selected cycles.
