* For optimizing the washing algorithm, the displaying time may be changed during washing-increased by

8minutes at maximum and decreased by 4 minutes at maximum.

* If the Detergent quantity is put more than the standard, for increasing the rinsing performance, it automatically

adds rinsing, and the remaining time may be increased.

* The standard detected by the sensor changing the algorithm is set by the normal standard. It may not be same to

the washing habit of a specific user. So, it does not matter that the user uses it according to her/his washing habit.

* The sensor for a Detergent quantity is designed to detect based on a synthetic Detergent powder. If you put a

liquid one or a natural one or too much bleaching agent, the detecting ability of the sensor may be decreased.

Use to set a delayed finishing time.
The time increases when the button
is pushed.
The following settings are indicated

To cancel delay time, turn the power
switch off.

Use to adjust the WATER LEVEL as required. The appropriate amount of
Detergent is shown next to the WATER LEVEL in the WATER-
DETERGENT diagram

WATER LEVEL is automatically selected for FUZZY (normal) program.
The following settings are indicated as the button is pushed  
LARGE         LARGE . EX-LARGE        EX-LARGE        SMALL

Use to select Water Temperature. 
Pressing the button allows you to select
COLD

WARM (HOT&COLD)

HOT      COLD respectively.  
Default setting is COLD.

It only operates in FUZZY Program.
During being detected by the sensor, the LED flashes green, orange 
and red in turn. And, after detecting, the LED lights a specific color
according to the detecting condition as follows:  

If the current washing condition (Detergent quantity, Water
Temperature, water quality, etc.) is determined as better than the
standard one, it optimizes the algorithm to save the energy by
decreasing washing time/strength,  and the LED automatically turns
to red.  
If the current washing condition is determined as worse than the
standard one, it optimizes the algorithm by increasing washing
time/strength, and the LED automatically turns to orange.
If the current washing condition is determined as equal to the standard
one, the algorithm has no change and the LED turns to green.

According to kinds of
laundry, soiled extent or
washing habit you can
select suitable WASH
OPTION manually.
By pressing the button
WASH OPTION is
changed.
