1 Washing Heater isn’t reworking after reach decision temperature.
2 The washing time is divided into the heating time and the main washing time that follows it. The heating time is gone
immediately after the heating is finished or stopped until the heating is completed.
3 The heating time for the standard course with water temperature of 40 degrees includes seven minutes without any heating in
the early stage. During this period, the textile is soaked in water fully before heating can be done, so that the temperature drop
in the washing tank caused by water supply after heating starts can be prevented.
4 The main washing time of 40 minutes is only for the standard course with water temperature of 40 degrees.
5 If the LS is greater than 480 for the standard course, one hour of extra washing time is added. The result is 2:47.

5) Medium spins
1 In the medium spin cycle, the designated rpm is achieved for each course After performing pre-B and B spins
twenty times, if it fails to enter into drying R, then it skips to the next operation.
2 When washing is terminated, load sensing is done to detect the amount of water before performing the first
medium spins By changing the reference value for unbalance depending on the amount of water, the main spin
operation can be performed
3 The medium spin for the sports shoes does not perform balanced spins For three minutes, instead of the main
spins, the motor operates at 45 rpm (10 sec on, 10 sec off)
4 The stocking course omits the medium spins cycle.
33
2-3 Spin Sequence
1) Water discharge
1 It is done according to functional organization 3-5, water discharge sequence.
2) Balanced spin
1 Depending on the amount of water, 3 steps of unbalance checks are done. If the criteria is satisfied, then it
advances to the next stage, spin R.
2 Spin B refers to the unbalance detection area at 350 rpm. If the amount of unbalance exceeds the reference value,
then it turns back to the textile attachment region.
3 Press the pause button in the middle of spin B. It restarts at the textile unfolding region.
4 The stocking and the lingerie course omits the unbalance region of 350 rpm.
5 The hand cloth/stocking/lingerie course reduces the duration of spin B by one minute. In other courses, reduction is
two minutes.
3) R (Real) spins
1 After passing spin B, spin R continues until the entire spin operation is completed.
2 Depending on the selected spin operation, the target rpm can be varied.
3 During the standard and heavy spin operation, the unbalance value is measured to determine the final target rpm.
4 If drying is selected and medium spin is selected, then the strongest spin sequence is performed.
5 If acceleration during spins is stopped, the cycle continues at constant rpm and performs braking.
6 If you press the pause button during spins, braking will stop the motor.
4) Spins for the sports shoes
1 No spin B is performed.
2 Like the washing motor operation, it repeats on/off operation with an interval of 10 seconds for five minutes at 45
rpm.
3 To remove water, textile pulling is skipped and low temperature drying is done for 36 minutes.
4 When the cycle is completed, to clean the tub, one cycle of rinsing and medium spin is used.
5) Hand cloth spins
1 Spin B’s duration is one minute.
2 The main spin time is 1 minute. The speed changes quickly from 350 rpm to 710rpm.
3 Textile pulling is skipped. When the cycle is completed, to clean the tub, one cycle of rinsing and medium spin is
used.
6) Stocking course spins
1 Spin B’s duration is one minute.
2 Spin B reaches 160 rpm. (350rpm and ascending region omitted.)
3 The main spin’s duration is 1 minute and the motor turns at 160 rpm.
4 To reduce damage to the stocking, textile pulling is omitted.
7) Lingerie spins
1 Spin B’s duration is one minute.
2 Spin B reaches 160 rpm. (350rpm and ascending region omitted.)
3 The main spin’s duration is two minutes and the motor turns at 200 rpm.
4 To reduce damage to the lingerie, textile pulling is omitted.
34
2-4 Termination
1) Textile pulling
1 After the spin is completed, the laundry is taken off from the drum wall to prevent wrinkles. It lasts for 30 seconds.
2 The motor operation depends on the type of textile pulling.
3 No textile pulling is done for soft textile, sports shoes, hand cloths, stockings and lingerie.
2) Termination
1 The buzzer sound will be heard for 10 seconds after completing textile pulling. Also the power is off.
2 If a drying cycle is added, then it will proceed to drying.
3 When termination begins, the door lock is released.

2 During wrinkle-free operation, the motor only operates) The fan motor and the drying v/v do not operate.
3 If you press the pause button during wrinkle-free operation, the motor is stopped and the door is opened.
2-6 Steam operation
1) Steam water supply
1 In steam operation, the water is supplied twice for one minute each.
2 Constant temperature control is done until reaching the initial phase steam water supply point.
3 If the laundry is soaked in the water and the water level drops, then water is supplied again) To reduce the number
of water supplies, the water supply level is set to 10mm higher than the steam point (1.5 phase).
4 Depending on load sensing or the course setting value, the water supply level is chosen to be low or extra low.
5 If powder DET is injected, then the main washing valve is opened and closed five times.
6 If liquid DET is selected the liquid DET stirring motor operates for 30 sec for low levels and for 20 sec for extra
low levels) At this time, the main washing valve operates too.
7 When liquid DET is fully injected, then washing water supply including constant temperature control begins.
8 If powder DET is selected or liquid DET injection completion is memorized, then liquid DET injection process is
skipped.
9 If the water supply is completed, to clean the DET box, the main washing valve and the reserved washing valve
operate for 10 seconds.

3. Main Function of PCB Program
3-1. LOAD SENSING
1) Water level-determining load sensing
1. When the standard, boiling and saving boiling courses are selected, load sensing is performed.
2. Prior to the washing cycle, sensing is performed on dry laundry.
3. After running the motor at 65 rpm, the rotation time for the drum is measured to determine the
amount of laundry.
2) Spin B load sensing
1. After the washing cycle is terminated, in the first medium spinning condition, sensing is performed
on wet laundry.
2. After running the motor at 65 rpm, the rotation time for the drum is measured to determine the
amount of laundry.
3. Depending on the measured amount of laundry, the unbalance reference value for Spin B in the main
spinning cycle and the medium spinning cycle is selected.
3) Load data
1. Water level-determining load data
A value to determine the water level for washing.

1. Divide the laundry attachment region into two levels (35, 95rpm) and shift the ascending speed from 35 to 95 rpm
between 5 rpm and 45 rpm every second to improve the condition of laundry attachment.
2. The unbalanced load is detected twice at 95 rpm and once in the region ascending to 350 rpm and once at 350 rpm.
3. In case of turn back due to being unbalanced, you should return not to the beginning of the balanced spin sequence
but to the laundry pulling region.
4. The balanced spin time is set to 2 minutes. When 350 rpm is passed, it is reduced by two minutes.

- Even if you select the strongest spin mode, as long as the LS value is greater than 340, it will only reach 820 rpm.
3) Organization of the balanced spin cycle
1. In the medium spin cycle, a max 20 times of balanced spin can be performed. If it fails to enter spin R after twenty
times of balanced spin, spin R is abandoned and it moves to the next cycle.
2. If it fails to enter spin R region after attempting 20 balanced spins in the main spin cycle, then controlled rinsing is
done once and spin B is performed twenty times.
3. If it fails to enter into spin R after 40 times of spin B including one time of controlled rinsing, the UE error message is
displayed.
4. Controlled rinsing follows the same sequence as the rinsing cycle in the standard course.

: Water supply reference level. After reaching the reset water level, 30 minutes pass before the spin begins. The minimum
necessary water level required for operation of the heater.
2. Safety
The water level where the door can be opened. The door only opens when it is below the safety water level.
3. Small water level
: Water level corresponding to ‘small’ selected as the washing water level.
4. Low water level
Water level corresponding to ‘low’ selected as the washing water level.
5. Rinsing water level
: Water level for rinsing selected in all courses except hand cloths, stockings or lingerie.
6. Medium rinsing water level
: Water level for rinsing selected in the hand cloths, stockings or lingerie course.
7. Clean rinsing water level
: Water level when clean rinsing is selected.
8. Overflow water level
The water level where forceful discharge is deemed necessary because the water level is too high. When this level is
reached, the water supply is halted and then it is discharged until it reaches the reset water level.
41
3) Constant temperature control
To minimize the energy consumed by the heater and reduce the time required for washing, the cold water v/v and the hot
water v/v are properly controlled until the required water temperature is reached.
1. After operating the hot water v/v until it reaches the water level where it is possible to detect the water temperature, if it
fails to reach the target temperature, the hot water v/v will continue to operate. If the target temperature is met, then the
cold water v/v is operated.
2. Depending on whether the target temperature is reached, the cold and hot water v/v keeps turning on and off. In other
words, to prevent the water temperature from continuing to rise after reaching the target temperature, the hot water v/v
is turned off and the cold water v/v is turned on. As the cold water is supplied, the water temperature drops and when it
is 5 degrees below the target water temperature, then the hot water v/v is turned on and the cold water v/v is turned off
to raise the water temperature.
3. For the water supply cycle shown in 1 and 2, if the water level is met, then the water supply stops and it moves onto the
next washing cycle.
4. In the earlier stage, the hot water valve is used to supply water. If the hot water valve is closed or not connected then
there would be no difference in water level for 60 seconds. In this case, the constant water temperature control is
ignored and only cold water is supplied.

120 seconds.
3. If it fails to reach the reset water level for 10 minutes, ‘OE’ is displayed.
3-8 Detergent sensing
1. If no liquid detergent or softener is in the detergent container or detergent has been used less than twice, the sensor
determines that there is no detergent.
2. If makes such a decision, then the ‘No detergent’ or ‘No softener’ LED is on.
3. If it determines that there is no detergent in the early stage, then the ‘No detergent’ or ‘No softener’ LED will blink and
the buzzer sound will be heard.
4. If it determines that there is no detergent during the cycle, then the ‘No detergent’ or ‘No softener’ LED will be turned
on and the cycle will progress regardless.
5. If the liquid detergent is selected but no liquid detergent is detected in the early stage, the cycle can’t progress.
6. If the powder detergent is selected but no powder detergent is detected, then the ‘No detergent’ LED is not turned on
and there is no buzzer sound.
