1. Cotton Course is for all cooton clothes such as towel, diaper and the same course as
Normal Steam Course.
2. At the Steam Washing, Washing Time is 30min for Heavy Stain, and 20 min for the other
course.
3. Finishing Washing is the heating stroke to be reached up to Wash Temp, and if Wash
Temp. of Washing is 30-40°C, time is 5min, and if 60°C, time is 10min, if 95°C, time is
30min.

2. Main function of PCB program
2-1. LOAD SENSING
1) Deciding the water level
1 Cotton, Whites, ECO-White course will be followed by this process.
2 Check the water level with dry laundry at the starting wash.
3 Check the water level by using motor output data during 20 sec, 65 rpm.
2) Deciding Spin Starting Step.
1 Check after finishing washing step with wet laundry.
2 Checking by using motor output data during 20 sec, 65 rpm.
3 The decided data is different depending on loading condition.
2-2. BALANCE SPIN
1) Motor running during balance spin.
1 Spreading the laundry : Rotating the same 45 rpm with left and right direction alternatively.
2 Attaching stop : Attaching the laundry to drum inside with constant speed.
3 Unbalance checking point : First step, check the U.B at 95 rpm, 160 rpm.
Second step, check the U.B at 95 rpm, 350 rpm.
Third step, at 300 rpm. if the unbalance data is over the criterion,
This process will be repeated.
4 Drain step : Drain at water around 160 rpm.
5 After drain, check the unbalance data again. This is so-called balance spin step.
2) Property of balance spin.
1 Conducting 10 times maximum.
2 If the washer can not pass balance spin step during 10 times, then water will be supplied.
3 If the washer can not pass 20 times of balance spin, UE error mode will be displayed on PCB.
27
2-3. DOOR S/W
1) The working principle of Door S/W
1 Door Locking
Bimetal on ( 3 sec) --> solenoid (supply 20msec pulse 2 times)
2 Door Unlocking
Bimetal off --> solenoid (supply 20msec pulse, until unlock)
3 After door locking, all parts can work normally.
4 After pressing power button, if the temperature of wash thermistor is over 50°C or the water level is
over the safety level, the door will be locked.
6 The door will be unlocked immediately after all processes are finished.
7 The door can be opened during processing if there is no problem to unlock.
28
2) DOOR OPEN SYSTEM
1If add the laundry during washing, press the door unlock button.
2Door open sequence at abnormal condition.

2-4. Child Lock
1 Press the “TEMP”. and “DRY” button simultaneously during processing.
2 Under the Child Lock function, only power button is working.
3 During Child Lock function, CHL will be displayed on PCB.
4 In order to unlock Child Lock mode, press "TEMP" and "DRY" simultaneously.
2-5. The sequence of drain
1 If the checking time to reset point is below 1 min, the remaining drain time is 30 sec.
2 If the checking time to reset point is over 1 min, the remaining drain time is 2 min.
3 If the checking time to reset point is over 10 min, OE singal will be appeared on PCB.
4 If the temperature is over 50°C, the water will be supplied to high water level, then the drain will
start.
30
3. Convenience service functions(test mode)
1. T esting Mode
PCB and other electronic parts will be tested without water supply whether they are normal or not.
1) Process : press power button --> press "SPIN" button 3 times with pressing "WASH" button --> 'L d' will be shown on LED -> Whenever pressing "TEMP" button 1 time, below process will be occurred.
L C (Lock Closed) --> F ( Fan Motor) ---> H (Hot V/V) --> C (Cold V/V) ->
P (prewashing V/V) -> d ( dry V/V) -> bb (bubble) -> dr (drain motor) ->
L O(Lock S/W Open)
2) More details
1When turn on 'LOCK' signal, all process is conducting normaly.
2When working starts, the PCB displays all the sensor conditions.
3In this case, BLDC Motor is not tested. In order to test it, select spin or rinse.
2. Continous testing mode
1) Process : after pressing "WASH", "RINSE", "SPIN" button simultaniously , press "POWER" button.
ALL LED On/Off 1 time --> L C (Lock Closed) ---> R (Motor right) --> L (Motor Left) --> F ( Fan Motor) ---> H
(Hot V/V) --> C (Cold V/V) --> b (pre-wash V/V)
--> d ( dry V/V) --> bb (bubble) --> h1 (HEATER W ASH)--> h2(HEATER DR Y) --> dr (DRAIN MOT OR On) ->L O(Lock S/W Open)
2) More tails
1LED test can be done with all LED On.
2All sensor conditions will be shown on PCB during processing.

While rotating DRUM, DRY HEATER applice heat to air and FAN blows it into DRUM evaporating water in the laundry.
• Evaporated water is sucked into CONDENSING DUCT, and condensed in DUCT contacting WATER SUPPLY (condensed water
is extracted through DRAIN HOUSING).
• Dry function is performed by continuous repetition of evaporating and condensing circulation as above.

5) TROUBLE SHOOTING OF DRY SYSTEM
✦
HEA TER DR Y
Function : heating the air during dry
• FAILURE MODE : * "H7" - The air cannot be heated to 10°C during 2 min.
• CHECKING METHOD : * Check the resistance of heater coil and replace with new one.
✦
Thermistor
Function : sensing the air temperature.
• FAILURE MODE : * The air cannot be heated even though water is supplied.
* "H1" - shot or cut-off
* "H3" - air temp. is reached over 150°C
• CHECKING METHOD : * Check the resistance of thermistor, replace with new one.
✦
FUSE TEMPERA TURE
function : protecting from the fire hazard or overheating, if the temp., rises over 128°C, power supply will be cut-off.

6) LACK OF DRY PERFORMANCE
• Situation : after drying, the clothes still get wet.
cause) ☞The laurdry amount is more than the recommendation capacity 7.0kg.
☞Condensing cold water is not supplied.
☞Clogging Bellows Duct results in poor air circulation.
