3-3. MAIN FUNCTION
1) Auto power S/W off function
● After power on, the auto power S/W off function automatically switches power off for you if you do not
press selection button for 10 minutes
● After selecting the function, the auto power S/W off function automatically switches power off for you if
you do not press start/pause button for 10 minutes
● until 5 minutes past, After finishing the last function, the auto power S/W off function automatically
switches power off for you if you do not re-select the course button or manual button
2) Door open function
● Door just can be opened at water level 24.80 KHz over, water temperature 55℃ below, motor off, if
power is off door is not opened (only auto-door model)
● If door is open during the operating, all operating is halted, and door error message will be displayed
(2-digit panel displays "dE" 4-digit panel displays "door") and error melody will coming out
● Door open error can be cleared by closing the door. the operating keeps going on
3) Rinse hold function
● If rinse hold function selected, the operating is finished , the machine do not drain the water after last
rinse
4) No spin function
● If no spin function selected, the operating is finished after last rinse
5) Drain function
● Drain function is over, after pumping out the water for 2 minutes , without motor rotating
6) Pre-washing function
● Pre-washing function can be selected ,when you choice the following mode; cotton, coloreds, synthetics,
delicates, baby cotton, baby coloreds, baby delicates, baby stains
● Water level/reverse time is the same with the selected course
● Pre-washing takes about 16 minutes
7) Rinse+ function
● This function practises rinse process once more
12
8) Power-out compensation function
● If power is out on selected process, the process before power out is stored to EEPROM, once power is
back the process before power out continues.
● When power is back, washing process starts from the process at the point of the power out, rinse/drain
process starts from the initial process.

9) Water heater Error function
① This function starts working, when the heater works abnormally.
(this function begins sensing the heater 2 minutes later, after the heater operating)
② The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes
(Y=A2-A1)
- For 10 minute late, the variance of temperature(Y) is less than 2℃, "HE2"message is displayed on the
panel.
③ The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 11 minutes
(Y=A2-A1)
- For 1 minute the variance of temperature(Y) increases more than 40℃, "HE1"message is displayed on
the panel.
④ At this time heater, Error "HE2 (heater do not work), HE(overheated)" is displayed and all working
process off
⑤ The heater operating continues during heating hours, if washing hour is left over, the residual washing
process keeps going without heating.

10) Fuzzy washing function (weight-sensing)
☞ After finishing initial water supply,
when the fall of the water level needs supplementary water supply,
Sensing function perceives the weight with the supplementary water supply numbers and starts to work.
Under the course of Cotton, or Coloureds, if the supplementary water supply numbers become over
2 times the function is going at default condition ( high water level ), if 1 time that is going at middle
level, if 0 below low water level, heating hours and rinse hours depend on the above data.
ECO PRE mode is selected, the process going on at default condition.

11) Bubble - detecting function
At the each condition of washing&dehydrating , rinse&dehydrating , hydrating, bubble -detecting function
works, this function works 5times normally, if the function detects bubbles at 6 times , the bubble-detecting
function stops and go on to the next process.
● The bubble-detecting function during washing & dehydrating to rinse & dehydrating
after 2 times instant dehydrating and before main dehydrating, if the water level is under 24.50KHZ, Bubble
→ Detecting function thinks there are bubbles and add the bubbles-removing rinse, needing hours are above
hours and 8 Min 40 sec.
→ The bubble-detecting function during single hydrating process
after 2 times instant dehydrating and before main dehydrating , if the water level is
24.50KHZ below or
during main dehydrating, water level data is 24.50KHZ below Bubble-detecting function thinks there are
bubbles and add the bubbles-removing rinse 1 times, needing hours are above hours and 5 min 50 sec.

12) Unbalance detecting & laundry balance positioning system
① Just before the hydrating process and just after reversal rotation for balancing laundry position, this
function is carried out
② The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm
for initial 6 sec
③ Next 12 sec, the rotation increases the speed from 50 rpm to 95 rpm slowly
④ During the next 8 sec, drum rotates at the speed of 95 rpm, the sensor decides the degree of laundry

13) R.P.M control
The rotating motor enables the magnetics( i.e generator) to generate magnetic flux in proportion to r.p.m,
magnetic flux induced by coil sensor in the opposite side produces the wave like the figure below to dΦ/dt
and via rectangular wave generating circuit, the waves reaches MICOM and micom controls r.p.m with the
pulse, count and cycle inputted by program.

call. Below information is prepared for exact trouble diagnosis and suitable repair guide.
Caution for the Repair and Replacement
Please follow below instruction for the trouble diagnosis and parts replacement.
1) As some electronic components are damaged by the charged static electricity from the resin part of
wash machine or the human body, prepare the human body earth or remove the potential difference of
the human body and wash machine by contacting the power supply plug when the work contacting to
PCB is executed.
2) Since AC220~240V is applied to the triac T1 and T2 on P.C.B, the electric shock may occur by touching

1. An occurrence of an Error will make a sound of error melody for 5sec and continuously show one of the
Error Displays from the following errors. (But, Fault Check Led will flash for 0.5sec.)
2. All of the steering parts will be off at that time until that error was released.
3. Water Supply Error
- If there is no higher change in water frequency than 100Hz for 2 minutes during the initial time of water
supply and if water level doesn't reach the preset level in 10 minutes, this error will occur.
This error will be released using Start/Pause button, which performs the initial condition of operation.
- Display : “4E”
4. Water Drain Error
- If water level frequency is still lower than the reset level frequency (25.20kHz) in 10 minutes after
starting of water drain, this error will occur.
This error will be released using Start/Pause button, which performs the initial condition of operation.
- Display : “5E”
5. Over Flow Error
- If an abnormal water level frequency is sensed (for occurrence of Over Flow :21.00kHz), Auto Power Off
may release this error and continuously progress water drain until the frequency reached 25.00kHz.
- If Over Flow is also sensed even after the following check of water level frequency indicating that error,
it functions to progress water drain.

11-2. TERMINOLOGY
1) ASSY-MAIN PCB (Imbalance Sensor)
→ To prevent the laundry from gathering on one side of the tube causing noise and vibration, the
washing machine uses an imbalance detection device that evenly disentangles the laundry before
the hydrating cycle starts.
2) DOOR-LOCK S/W
→ Prevents the door from being opened while a cycle is in progress. For safety purposes, it keeps
the door locked even in pause mode or after the washing cycle unless the water level frequency
is greater than 24.8Khz (anti-overflow level) or the inside-tube temperature is less than 65℃ in
the hydrating cycle, and 55℃ in the washing cycle.
3) SENSOR-PRESSURE (Anti Over-Flow)
→ When the water supplied is more than 2/3 of the tube capacity due to a malfunction of the water
supply valve, this device automatically starts water-draining and displays "OVER-FLOW
ERROR(E3)" on the LED.
4) THERMISTOR
→ Keeps sensoring and controlling the temperature inside the tube to keep it below your settings.
5) ASSY-THERMAL FUSE (Anti Over-Heat)
→ When the washing heater is overheated due to an error in the thermistor or any other
malfunction,
the assy-thermal fuse (built in the heater) is automatically activated to disconnect the power for
your and the product's safety.
6) ASSY-MAIN PCB (Sensitive Laundry Protection)
→ To avoid any damage to sensitive laundry, the tube temperature is detected and "ERROR(E8)" is
displayed on the LED for Wool or Lingerie courses when the temperature is over 50℃.
7) THERMOSTAT (Anti Over-Heat)
→ When the heater (drier) overheats from an error in the thermistor or any other malfunction, the
thermostat (installed on the drying duct) is automatically activated to disconnect the power for
your or product's safety
8) CHILD LOCK
→ Prevents children from playing with the washing machine.
55
9) PRE-WASH
→ The machine does a preliminary wash of about 10 minutes prior to the main wash. This is
particularly effective for cleaning badly stained laundry.
10) WEIGHT SENSOR
→ The tube automatically rotates when no water is supplied to detect the laundry weight so that the
proper wash time can be determined. (Standard, Boiling, Economy Boil and Dirt courses and
Toweling and Drying cycles)

11-4. ELECTRICAL WARNINGS
To reduce the risk of fire, electrical shock, and other injuries, keep these safety precautions in mind:
. Operate the appliance only from the type of power source indicated on the marking label.
If you are not sure of the type of power supplied to your home, consult your appliance dealer or local power
company.
. Use only a grounded or polarized outlet. For your safety, this appliance is equipped with a polarized alternating
current line plug having one blade wider than the other.
This plug will fit into the power outlet only one way. If you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug still doesn't fit, contact your electrician to replace your outlet.
. Protect the power cord. Power supply cords should be routed so that they are unlikely to be walked on or
pinched by items placed on or against them. Pay particular attention to cords at plugs, convenience receptacles,
and the point where they exit from the unit.
. Do not overload the wall outlet or extension cords. Overloading can result in fire or electric shock.

12. CIRCUIT DESCRIPTION
12-1. OVERALL SYSTEM
58
12-2. AC Input & Power Circuit
▶ Function
Generates a required DC power of 12V
or 5V in case of supplied or disconnected
AC power.
▶ Description
- When AC 220V is applied to CN3, D17
D20 transforms it to DC 300V.
- DC 300V is generated for the LVT1
secondary source by IC3 and PC1
turning on/off.
- The secondary 12V depends on the
ZD1 value.
- The 12V for the LVT1 secondary
source is transformed to DC 5V
through IC4.
59
12-3. Driving System Circuit
▶ Function
Controls each driving system (VALVE, DOOR
S/W, DRAIN-MOTOR) by turning RELAY or
TRIAC on/off.
▶ Description
- MICOM outputs a high signal of 5V from pin
# 1 - 7 of IC7 and IC9. - Then, pin # 10 to 16 of IC7 and IC9 are
electrically grounded (0V).
- When pin # 10 to 16 are grounded, this
creates an electric potential difference from
the 12V that turns on RELAY 5,6,7 and
TRIAC2,3,4,5.
- The operating parts (VALVE, DRAIN-MOTOR,
DOOR S/W) connected to CN9 turn on if
they are supplied with power.
60
12-4. Motor Circuit
▶ Function
Supplies power to the motor and turns it
CW/CCW (Right / Reverse direction).
▶ Description
- The operation of TRIAC1 is the same as
that of the driving system.
- If the electric potential of R48 is grounded
(0V), TRIAC1 turns on.
- CN1 detects if the door is locked or
unlocked. If unlocked, it does not apply
power to the motor even if TRIAC1 turns on.
- If the door is unlocked and TRIC turns on,
the motor connected to CN4 is supplied with
power and drives CW (right direction).
- Under such conditions, turning RELAY3 on
will drive the motor CCW (reverse) as the
wiring is switched to CCW.
- Turning RELAY4 on will switch the winding
of the motor to one for higher driving.
61
12-5. Sensor Detection Circuit
▶ Function
Detects signals from the sensor and controls
the current system.
▶ Description
- The water level sensor is connected to pin 4
of CN7.
- The frequency of the level sensor changes
according to the water amount in the tub.
- Then, the frequency is input to MICOM pin
48 for detecting the water amount.
- The DHSEH sensor is connected to CN7 pin
5 and CN6 pins 3,4.
- The resistance of the temp. sensor changes
according to the ambient temperature. The
changed resistance is applied to R50 and
R51.
- The voltage applied to R50 and R51 is
decided according the temp. MICOM stores
the value.
- When voltage is applied to MICOM pins 22
and 23, MICOM compares it to the predefined one before detecting the current
temp.
62
12-6. Motor TACHO Input System
▶ Function
Detects the current RPM of the motor and
controls the output.
▶ Description
- The motor TACHO sensor is connected to
CN10 B-pin.
- According to the current RPM of the motor,
a square wave is applied to pin 8.
- The square wave that is input to TR2 BASE
turns the motor on if high (5V), and turns it
off if low (0V). And this operation will be
inverted to TACHO NET for a clear wave
with no noise.
- The signal is applied to MICOM pin 13.
Then MICOM counts the frequency of the
input signal and detects the current RPM of
the motor.
63
12-7. Silver Nano System
▶ Function
Applies the electric current to the silver plate during
the water supply and uses the silver water to
perform the bacteria-free or sterilization processes.
▶ Description
- Selects the silver nano feature to operate
the system.
- Supplies water to the two silver plates AG_B
and AG_A.
Then, SINAL_A and SIGNAL_B output a
high signal of 5V.
- Both SIGNAL_A and SIGNAL_B repeat this
for 15 seconds outputting a high signal of 5V.
SIGNAL_A output turns TR1 and TR6 on to
generate a potential difference between the 12V
and the grounding for causing the current to flow.
SIGNAL_B output turns TR4 and TR5 on to
generate a potential difference between the 12V
and the grounding for causing the current to flow.
- The flowing current is transformed to a voltage by
the resistance of R27.
- Then, the voltage is applied to IC1 pin 2 and used
for detecting and controlling the flowing current.
