2. FEATURES & TECHNICAL EXPLANATION
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.
Automatic Wash Load Detection
Automatically detects the load and optimizes the washing time.
Child Lock
The child lock prevents children from pressing any button to change the settings
during operation.
5
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.

5-3. SPECIAL FUNCTIONS
The option buttons also activate special functions, including CHILD LOCK, LOAD SIZE, TUB CLEAN and
SIGNAL ON/OFF Press and hold the option button marked with the special function for 3 seconds to activate.
CHILD LOCK
Use this option to prevent unwanted use of the washer or to keep cycle settings from
being changed while the washer is operating. Press and hold the PREWASH button for
3 seconds to activate or deactivate the child lock function.
The child lock indicator will be shown in the display, and all buttons are disabled except
the ON/OFF button.
NOTE: CHILD LOCK lasts after the end of cycle. If you want to deactivate this function,
Press and hold the STAIN CARE button for 3 seconds.

5-4. Explanation of each process
No. Process Explanation
1. Stay • Electrical power is supplied.
• Washer is ready to work and the micom is in the active mode.
2. Water
supply
• After loading laundry and selecting a course and a cycle, water is
supplied and drum rotates.
• When a user selects Pre-wash course, water is supplied through pre
wash valve.
3.
Soaking
and washing
laundry
• To get laundry wet, drum rotates clockwise and counterclockwise.
• If water amount is insufficient at this time, the Inlet valve will supply
water again.
4.
Heating and
washing
• The heater heats the water in drum to the selected water temperature
and drum rotates for washing.
5.
6.
Washing
and heating
/ washing
• When the water temperature reaches to the selected temperature,
the heating stops and only the drum rotates.
• If water temperature becomes lower than selected because of
re-supplied water, the heating starts again.
7. Washing • Fuzzy logic decides washing time according to the laundry load, water
temperature, and other factors.
8. Drainage • A pump motor drains the water from the drum.
• After sensing drained water amount by water level frequency, spin starts.
• When a heating course is selected, stay cooling process is performed to
decrease the water temperature gradually to prevent laundry from being
damaged and for safety reasons.
9. Untangling
(Sensing
eccent-
ricity)
• It balances laundry load and senses the eccentricity of the load, to only
allow spinning without vibration.
• If the eccentricity is worse than the allowed level, it repeats the
disentangling process. When the repeated time is more than allowed
level, it displays UE.
• If the eccentricity is good, the intermittent spin starts.
• During this process, the drain pump works for drainage intermittently.
17
No. Process Explanation
A. Intermittent
spin
• To reach the correct set speed, the motor rotates clockwise and
counterclockwise directions after spin process starts.
• If the water level frequency is lower than 23.0 kHz,
a washer senses suds and starts suds removal process.
B. Rinse
spin
• In this process, the remaining water during washing process is
extracted and the selected speed is kept.
• Removing suds process is in active mode at this cycle.
C. Remaining
spin
• After spin finishes, the drum rotates by remaining spin power until it
stops. Motor power is off.
• This process is overlapped with next process.
D. Rinse water
supply
• Water supply for rinse process.
E. Rinse • Rinsing process.
F. Last
drainage
• After spin finishes and power is not supplied to motor, the drum
rotates by remaining spin power.
• If rinse hold is selected, the drainage is not proceeded after rinse
finishes.
G. Disentangling • The same as item 9.
H.
Intermittent spin
• The same as item A.
I. Main spin1 • The same as item B.
J. Main spin2 • At the end of a main spin, the spin speed will reach the selected rpm.
K. Remaining spin • The same with item C.
L. Disentangling • After spin finishes, disentangling starts to remove unbalanced
laundry.
M. End • After ‘end’ signal is displayed, it stays for 8 seconds and power is
automatically turned off. (Auto type door switch)
• After door switch is off, end signal is displayed in the case of
manual type and it takes around 2 minute to turn off door switch.

7. TEST MODE
7-1. SAFETY CAUTION
There’s built-in AC 120V and DC power in output terminal of PWB assembly in common.
Be careful electric shock when disconnecting parts while trouble shooting. (Wear Electro
Static Discharge gloves when working.)
After cutting off the power when changing PWB assembly, disconnect or assemble.
Be careful static when handling PWB assembly, and use Electro Static Discharge plastic
pack when delivering or keeping it.
7-2. LOAD TEST MODE
7-3. HOW TO CHECK THE WATER LEVEL FFREQUENCY
1. Press the SPIN SPEED and SOIL LEVEL buttons simultaneously.
Press the WASH/RINSE and DELAY WASH button simultaneously.
The digits indicate the water level frequency ( x.1 kHz ).
= 24.1 kHz
So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz
2. Press the Power button, while the above condition. Then buzzer will sound twice.
3. Press the Start/Pause button repeatedly to cycle through the test modes.
