2. FEATURES & TECHNICAL EXPLANATION

2-1.FEATURES

n Automatic Process From Washing To Drying

Automatic process from washing to drying can be

selected easily.

n More economical by using 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.

n Direct Drive System

The advanced Brushless DC motor directly drives the

drum without belt and pulley.

n Child-Lock

The Child-Lock prevents children from pressing any

button to change the settings during operation.

n Built-in Heater

Internal heater automatically heats the water to the

optimal temperature on selected cycles.

n Low noise speed control system

By sensing the amount of load and balance, it evenly

distributes load to minimize the spinning noise level.

n Auto Restart

If the washing machine is turned off by a power failure, it

will restart automatically from the position it stopped.

2-2. NEURO FUZZY WASHING TIME OPTIMIZATION

To get the best washing performance, optimal time is determined by the water temperature,

the selected washing temperature, and the size of the load.

2-3. WATER LEVEL CONTROL

This model incorporates a pressure sensor which can sense the water level in the tub.

The water supply is stopped when the water level reaches the preset level, the washing

program then proceeds.

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