More economical by Intelligent Wash System
Intelligent Wash 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.
Direct Drive system
The advanced Brushless DC motor rotates the Drum directly
without belt and pulley.
Child- ock
The Child-Lock system has been developed to prevent
children from pressing any button to change the program
during operation.
ow noise speed control system
By sensing the amount of load and balance, automaticaly
distributes load evenly to minimize the spinning noise level.
Auto Restart
Although the washing machine is turned off by a power failure,
it restarts automatically where it stopped when power is
supplied again. And it will be the same if the machine
unplugged and is plugged in again.

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- .WATER LEVEL CONTROL
This model adopts a pressure sensor which can sense the water level in the tub.
Water supply is stopped when the water level to the preset level, then the washing program proceeds.
Spinning does not proceed until the water in the tub reduces a certain level.
2-4.CONTROL OF DOOR OPEN
The door can be opened by pressing DOOR OPEN button after finishing program.
When the revolution of drum is stopped and in case water leel is below level 2, door can be opened by pressing the
