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.

Auto Restart

Auto Restart allows the program to restart all by itself in case of power failure. It does from the stage where it stopped. It will be

also the same when washer is plugged-in after unplugging.

Direct Drive System

The advanced Brushless DC motor rotates the drum directly

without a belt and a pulley.

2. FEATURES & TECHNICAL EXPLANATION

2-2.DETERMINE WASHING TIME BY FUZZY LOGIC

To get the best washing performance optimal time is determined by sensing of water temperature,

selected washing temperature and laundry amount.

2-3.WATER LEVEL CONTROL

This model adopts a pressure sensor which can sense the water level in the tub.
