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.
