    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.

    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.
    When the water level reaches to the preset level the water supply is stopped, then the washing program proceeds.
    Spinning does not proceed until the water in the tub reduces a certain level.
