2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Direct Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
Water Circulation
The detergent water from the drum is sprayed directly over the load ; 
this enables the clothes to get soaked more quickly during the cycle.  
The detergent suds can be removed more easily by the water shower during rinse cycle.
The water circulation system uses both water and detergent more efficiently.
Built-in Heater
Child Lock
The Child lock prevents children from pressing any Buttons to change the settings during
operation.
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.
Low noise speed control system
By sensing the amount of load and balance, it evenly distributes load to minimize the
spinning noise level.
Safety device (Aqua lock) 
Aqua lock System is designed for detecting water leakage during operation to prevent
water from spilling on the floor.  
Steam Washing and Refresh
Steam Washing features upgraded washing performance with low energy consumption.
Refresh cycle reduces wrinkles from dry clothes.

2-2. DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing the 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 reach the preset level, then washing program proceeds.
Spinning does not proceed until the water in the tub reduces to a certain level.
