5-3. SPECIAL FUNCTIONS
The option buttons also activate special functions, including CHILD LOCK, LOAD SIZE, TUB CLEAN, and
SPIN SENSE. Press and hold the option button marked with the special function for 3 seconds to activate.
CHILD LOCK
LOAD SIZE
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 CHILD LOCK. CHILD LOCK will be shown in the display, and all
controls are disabled except the ON/OFF button. The washer can be locked during a cycle.
At the beginning of the cycle, the washer tumbles the load and detects the weight of the
clothes.
The display will indicate the approximate load size in the LOAD SIZE display. This allows you
to Adjust the amount of detergent and other additives for best results and improved efficiency.
TUB CLEAN
SPIN SENSE
A buildup of detergent residue can occur in the wash tub over time and can lead to a mildew
or musty smell. The TUB CLEAN cycle is specially designed to remove this buildup. Press
and hold the EXTRA RINSE button for 3 seconds to activate this cycle. The display will show
a message to add liquid bleach to the dispenser. After the cycle has ended, open the door
and allow the drum interior to dry completely.
NOTE: Do NOT use this cycle with clothes, and do NOT add detergent or fabric softener.
To activate SPINSENSE :
While the washing machine is runnung in any cycle, press and hold the STAIN CYCLE button
for 3 seconds. The SPIN SPEED button light will blink while the washer is running to show
that SPINSENSE is active. The SPINSENSE function will remain active for every cycle, even
after a power failure.
To cancel SPINSENSE :
Press and hold the STAIN CYCLE button for 3 seconds to turn off the SPINSENSE
function
BEEPER ON/OFF
You may turn the end-of-cycle beeper on or off with the WATER PLUS button during the
cycle. Press and hold the WATER PLUS button for 3 seconds to turn the beeper off. Press
and hold the WATER PLUS button again for 3 seconds to turn the beeper back on.

Washing
Drainage
Untangling
(Sensing
eccent-
ricity)
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.
To get laundry wet, drum rotates clockwise and counterclockwise.
If water amount is insufficient at this time, the Inlet valve will supply
water again.
• The heater heats the water in drum to the selected water temperature
and drum rotates for 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.
• Fuzzy Logic decides washing time according to the laundry load, water
temperature, and other factors.
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.
• 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.

C. Remaining
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.
• 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.
D. Rinse water • Water supply for rinse process

After spin finishes, the drum rotates by remaining spin power until it stops.
Motor power is off.
This process is overlapped with next process.
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.
