2-1.FEATURES

■

Ultra Capacity

The Larger drum enables not just higher head drop and stronger centrifugal
force, but also less tangling and wrinkling of the laundry. Heavier loads, such
as king size comforters, blankets, and curtains, can be washed.

■

Direct Drive System

The advanced Brushless DC motor directly drives the drum without
belt and pulley.

■

Tilted Drum and Extra Large Door Opening

Tilted drum and extra large opening make it possible to load

and unload clothing more easily.

■

Steam Washing and SteamFresh

TM

Steam Washing features upgraded washing performance with low energy
and water consumption. SteamFreshTMcycle removes wrinkles from dry
clothes.

■

Automatic Wash Load Detection

Automatically detects the load and optimizes the washing time.

■

Built-in Heater

Internal heater helps to maintain water temperature at its optimum level for
selected cycles.

■

Child Lock

The Child lock prevents children from pressing any button to change the
settings during operation.

■

Auto Leveling Leg

It is located at the right rear of the product and automatically adjusts the
leveling of the leg in order to reduce vibration and noise.

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.

2-4. DOOR CONTROL

The door can be opened by pulling the door handle whenever washer is not in operation.

When the cycle is completed, the DOOR LOCKED light will turn off.

If a power failure has occurred while in operation, the door will unlock after 5 minutes.

Clicking sounds can be heard when the door is locked/unlocked.
