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.
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.

5-3. SPECIAL FUNCTIONS
The option buttons also activate special functions, including CHILD LOCK, TUB CLEAN, and SPIN SENSE.
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 OPTION button for 3 seconds to
activate or deactivate CHILD LOCK. CL will be shown in the display, and all controls are
disabled except the ON/OFF button. The washer can be locked during a cycle.
TUB CLEAN
Remove any clothing or items from the washer and close the door. Open the dispenser drawer
and add liquid chlorine bleach to the bleach compartment.
NOTE : Do not add any detergent to the detergent compartments. Excessive suds may
be produced and leak from the washer.
Close the dispenser drawer slowly. Power on the machine, press the OPTION button and then
select the TUB CLEAN. Press the Start/Pause button to start. After the cycle is complete,
leave the door open to dry around the washer door opening, door seal and door glass.
CAUTION : If there are small children in the house, care must be taken so that they
can not climb into or play inside the washer while it is open for drying.
SPIN SENSE
SPINSENSE can be used when there is a vibration problem, especially on wood floor
installations. To operate SPINSENSE press and hold the WATER PLUS button for 3 seconds
when the washing machine is running on any cycle. When SPINSENSE has been selected,
the SPIN SPEED button light will blink on and off continually to indicate that the SPINSENSE
function has been selected. Push and hold the WATER PLUS button again for 3 seconds to
cancel SPINSENSE. Once SPINSENSE has been selected, if will continue to function even if
interrupted by a power failure. SPINSENSE option cannot be selected during the spinning
cycle.

5-4. EXPLANATION OF EACH PROCESS
15
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
& 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. Washing • Fuzzy Logic decides washing time according to the laundry load, water
temperature, and other factors.
5. 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.
6. 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.

16
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 6.
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.

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
The washer must be empty and the controls must be in the off state.
