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.
SPIN
TIME DELAY
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, automaticaly distributes load evenly to minimize the spinning noise level.
Auto Restart
Although the washing machine is turned off by a power failure, it restarts automatically where it stopped when power is supplied again. And it will be the same if the machine unplugged and 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.

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 the washing program proceeds.
Spinning does not proceed until the water in the tub reduces a certain level.

5. OPERATION
Option
Extra Wash
• If the laundry is heavily soiled,
“Extra Wash” course is effective.
• Extra Wash is available in
Sanitary, Cotton and
Perm. press.
Extra Rinse
• This option can be used to add a rinse for people with sensitive skin. Selecting the
Extra Rinse button is also recommended when washing heavily soiled fabrics which needs a lot of detergent, or when the wash load contains towelling fabrics that have a greater tendency to retain detergent.
Rinse hold
If you desire to leave fabrics in the machine without spinning after rinse to prevent them wrinkling, you may select rinse hold by pressing the spin button.
If you want to drain and spin, when Rinse Hold function is proceed, Press the Start/Pause button to cancel the Rinse Hold function and select spin speed or program. Press the Start/Pause button again to start program.
If you want to drain only, select the no spin.
If lamp turns on, that function has been selected.
