2-1. FEATURES
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 
temperature on selected cycles.

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 uses a pressure sensor to determine the water level in the tub.
When the preset water level reached, water supply is stopped and the program proceeds.
W
ater needs to be below a preset level before spining will proceed.
