More economical by Intelligent Wash SystemIntelligent Wash System detects the amount of load andwater temperature, and then determines the optimum waterlevel and washing time to minimize energy and waterconsumption.

Direct Drive systemThe advanced Brushless DC motor rotates the Drum directlywithout belt and pulley.

Child-LockThe Child-Lock system has been developed to preventchildren from pressing any button to change the programduring operation.

Low noise speed control systemBy sensing the amount of load and balance, automaticaly

distributes load evenly to minimize the spinning noise level.

Auto RestartAlthough the washing machine is turned off by a power failure,it restarts automatically where it stopped when power issupplied again. And it will be the same if the machineunplugged and is plugged in again.

SPIN TIME DELAY

2-2.DETERMINE WASHING TIME BY FUZZY LOGICTo get the best washing performance optimal time is determined by sensing of water temperature,

selected washing temperature and laundry amount.

2-3.WATER LEVEL CONTROLThis 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.
