2-1.FEATURES

Automatic process from washing to drying. Automatic process from washing to drying can be selected easily. Washing capacity : 8kg/8.5kg/10.1kg(Cotton)/10kg Drying capacity : 4kg/4.2kg/10.1kg(Cotton)/6kg
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-Lock

The Child-Lock system has been developed to prevent children from pressing any button to change the program during operation.

Low noise speed control system
By sensing the amount of load and balance, evenly distributes load to minimize the spinning noise level.

Auto Restart

Although the washing machine is turned off by a power failure, it restarts automatically in its stopped process when power is supplied again. And it will be the same when the machine unplugged in operation 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.
