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.

2-1.FEATURES

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.

Water supply is stopped when the water level to the preset level, then washing program proceeds.

Spinning does not proceed until the water in the tub reduces to a certain level.
