Whirling washing tub* The laundry becomes cleaner

than ever since the laundry isturned over in the whirling tub andwashed by the beating of thehigher whirling embossing on thetub.

Washing by the strike ofthe strong falls* The strong falls vigorously strike

the full load of laundry or the largelaundry to clean. The light beddingis pressed even for the old dirt tobe thoroughly removed.

No detergent remnants in the deter-gent and the softener dispensers.* The powder detergent is solved to the liquid

detergent in order to prevent the contamina-tion of the environment.

* If the softener is put in the dispenser, it is auto-matically flushed during the rinsing cycle.

Detergent Compartment

Softener Compartment

Leveling feet* Since the leveling feet are

on the front, it is conve-nient to adjust by hand.

Large filtering net* Since the lint or other substances

are thoroughly collected by the fil-tering net that is more than 2 timeslarger than the existing one, youcan feel the difference by the farcleaner laundry.

Wider variety of rinseselection* By adding the rinse selection button,

during the rinsing cycle, not only wateris supplied, but also water can be addedto the higher water level than that of thewashing cycle and so on.Consequently, you have more choicesto select the rinsing mode.

Water spouting washing hands* The water spouting washing hands shoot up the water

columns in the water to prevent the laundry from being entan-gled. The water columns shot up by the water spouting wash-ing hands prevent the laundry from being entangled in substituted for the rod and they wash the laundry by scrubbing, which is the merit of the revolving board washer, as well. As a result, the cleaning ability is also excellent.

2-3 Main Functions

2-3-1 Washing Cycle1. Water Supply Mode1) In the water supply mode of each cycle, the valve for the corresponding water supply is on according to the water supply selec-

tion until the selected water level is reached.

2) The water level selection is as follows. (Unit: water amount-l, Frequency: KHz)

3) The selection of the water supply valve-ON for each cycle according to the water supply stated in Paragraph 1) is as follows.

Note) 1. When only the hot water is selected, for the initial 20 sec of supplying water at the beginning of washing, the cold watervalve is on.→ To avoid the damage of the cloth and to solve the detergent completely

2. While in rinsing, the water supply selection is applied only to the Rinsing 1 as shown in the table above. In the Rinsing2 or later, only cold water is supplied.

4) While supplying water, the corresponding lamp is ON/OFF at 1 sec interval. When the water supply is done, the correspondinglamp is on.

5) When supplying water is not done after the standard time allotted for supplying water is over, the remaining time does notdecrease.

6) When supplying water is done before the standard time allotted for supplying water is not over, the remaining time is compelledto decrease according to the allotted time and then the next cycle starts.

7) When supplying water is not done 60 min later after starting the water supply, the Water Supply Error mode is carried out.(including the water supply or the additional water supply for clearing the unbalance)

8) After supplying water is done, if the water level key is input and the selected level is higher than the previous one, water is sup-plied to the selected level. Meanwhile, the motor is off and the remaining time is not reduced while in supplying water.

9) Table of Water Supply Time for Each Water Level

2. Washing Mode1) After reading the selected water level and washing is carried out for 2 min or 9 min, the motor is off for 3 sec to read the fre-

quency of the water level. If the water level is lower than the selected water level, water is added to the selected water level andthen washing proceeds. The time for adding water does not exceed 30 sec.* While in rinsing, water is added 1 min later after the rinsing cycle starts.

2) Table of Water Current Pattern during the washing cycle of each water level for each course according to the washing selection(see the appendix)

3) For each course or each water level, the water addition mode is carried out 2 min or 9 min after the washing cycle starts and 1min after the rinsing cycle starts. The time out is 30 sec.Although the washing time is changed by the washing-adjusting key while in washing cycle after the water addition mode, thewater addition mode is not carried out.

4) In case that the water addition mode is carried out twice in a course, even though the time for any cycle is changed, no morewater addition mode is carried out.

5) When the washing time is changed after the water addition mode is carried out once, it is carried out once more within thechanged washing time.

2-3-2 Rinsing Cycle1. Draining Mode1) The draining valve is kept ON.

If the water level at the initial stage of this mode is higher than the reset, the delay mode is carried out for 50 sec after readingthe reset. If lower than the reset, it is carried out for 20 sec.

2) The remaining time decreases while the draining mode is carried out until the standard time for draining is over. After that, theremaining time does not decrease any longer.When this mode is done, the standard time for draining is considered to be over.

3) When the water level is higher than the reset in 15 min after starting the draining mode, the draining error mode is carried out.The buzzer sounds 5 times and the pause mode is carried out.

4) If the Start key is input during the step 3), the error is cleared, the time out is set to 15 min again, and then draining begins.

2. Intermittent Spin Mode1) If the door is open while in this mode, this mode is paused and the door open alarm (5 times of the door open melody) sounds.

2) If the door is closed while the door open alarm sounds, the alarm stops and the operation proceeds in the same way when theStart/Pause key is input.

3) When the safety S/W detects the unbalance while in this mode, the unbalance clearing mode is carried out.① Unbalance detecting mode

- Checker S/W detecting time: 20 ñ 449 ms- When the door is open (Reed S/W detecting), the drive part is turned off immediately after 20 ms is detected.

When the door is closed while the door open alarm sounds, the alarm mode is canceled, the draining valve is on in 10sec after it is off, and then the motor restarts after the draining valve is on.

➁ Unbalance clearing mode- When the unbalance occurs while in spinning after the washing cycle ends, this mode is carried out in the same way

when one rinsing cycle is added. When the unbalance is detected while in rinsing, water is supplied and then the nextrinsing step is proceeded. When the unbalance occurs during the final spin, the clearing mode is carried out up to twice.At the third time, the unbalance alarm sounds.

- At the beginning of the clearing mode, ‘the standard time for supplying water + 1 min’ is added to the initial remainingtime of the corresponding cycle. The clearing mode is carried out with the disentangling water current for 1 min aftersupplying water.

- When the unbalance error occurs, ‘UE’ flashes in the way of 1 sec ON/OFF and the error melody sounds 5 times.- When the unbalance occurs while in the spin only mode, the error alarm sounds.


3. Spin Mode1) This mode is carried out by turning the washing motor counterclockwise. The draining valve is kept on during the correspond-

ing spinning time.

2) The other functions are the same as those of the intermittent spin mode.

3) The spinning time after washing or rinsing, or the final spinning time is shown in the time chart.

4. Pause Mode1) This mode is carried out by turning off ML for 1 min 30 sec and keeping the draining valve on.

2) When the door is open while in the pause mode of the rinsing cycle, the door open error occurs. When the door is closed again,the restart mode is carried out.

3) When the door is open while in the pause mode of the final spinning cycle, the ending mode is carried out.

5. Draining Mode1) The same as the draining mode of the washing cycle.

6. Rinsing Mode1) When the selected water supply is done, rinsing starts according to the water level.

2) The rinsing time is 2 min 30 sec regardless of the number of rinsing cycles. However, in the Wool course, it is 2 min.

3) Table of Water Current Pattern during the rinsing cycle of each water level for each course (see the appendix)

2-3-3 Spinning Cycle1) The same as the intermittent spin mode or the spin mode of the rinsing cycle.

2) In the Wool course, spinning is carried out by 10-sec ON and 5-sec OFF.

2-3-4 Ending Cycle1) This mode is carried out when all the selected cycles are done.

2) While in this mode, the end melody sounds and all the drive parts are off.Meanwhile, ‘00’ is displayed by 1-sec ON/1-sec OFF.

3) When this mode ends, the automatic power relay off is carried out.

4. Cautions in Servicing

4-1 Before Servicing

1) When laying down the washer on the front side, if the floor isuneven, put a stand on the floor, and then carefully lay downthe washer so as not to damage the out-case.

2) When separating the top-cover from the out-case, be cautiousthat the wire bundle connected to the lower part does nottouch the sharp edge of the out-case or is not stretched.

3) When separating the top-cover, be cautious not to damagethe checker-S/W.

4) Do not drag the washer on the uneven floor, if avoidable. (Itmay cause to remove the rubber packing. If then, the violentvibration may occur during the spin.)


4-2 While in Servicing

1) When replacing the suspension-bar ass’y, make sure that the frontand the rear are not switched each other and that the parts of othermodels are not mixed. (During the spin, the violent vibration mayoccur.)

2) Structure of Ass’y-Damper & Cautions in Servicing

Caution

1) Be cautious not to apply grease on the area where no grease should exist.2) After replacing the damper, apply enough Albanian grease on the caller-suspension part.

Since there are few defective dampers among the recently produced ones owing to the thorough management, becautious when judging the product whether good or not.

4-3 After Servicing

1) First, select the installing location.• Set the direction of the drain hose according to the con-

dition of the place.• Keep the washer the minimum 10 cm away from the

wall.

2) Level checking• Adjust so that the bubble of the level indicator is in the

center of the circle.

● How to adjust the level

3) Leveling• If not level, adjust the leveling feet so that the washer is

level.• Be cautious not to put the hand under the leveling feet.

(It may cause to hurt the hand.)

* If not level, it may cause the severe vibration or afailure.Be sure to be level.

a. Pull the adjusting handle of theleft, right leveling feet on thefront to the front and push themto the left or right.

b. Adjust the washer upward ordownward to be level.

c. When the adjustment is done,pull the adjusting handle to thefront again to fix the levelingfeet.

4) Properly arrange the wire bundle at the bottom so that it isnot stretched even if the tub-ass’y leans. (If not, it may causevibration or noise during the spin.)

5) While reassembling the top-cover after being separated,ensure that the air-hose is not caught between the out-caseand the top-cover. (It may cause the occurrence of ‘No drain’or ‘No water supply’ error.)

Caution

* While separating or assembling the top-cover, the power-cord wire on the rear side may come out of the top-cover. Itmay cause the occurrence of a problem caused by nickingof wire while assembling the cover-TC. Therefore, ensurethat the wire does not come out of the top-cover before start-

ing assembling.

6. How to Disassemble

6-1 PCB-Ass’y Replacement

1) Remove the two cover-screws on the control-panel asshown in the figure, and then remove the 2 screws.

2) Push the control-panel to the front as shown by the arrowin the figure and pull it upward to separate.

3) Turn over the control-panel ass’y and remove the 5 screwson the PCB Ass’y.

4) Raise the ass’y gently to the direction to which the screwsare removed in order to separate the ass’y.

5) Separate the connector connected to the Ass’y PCB.❈ While separating the control-panel, be cautious not to

stretch the wire excessively. While in assembling, ensurethat the wire is not caught in the groove of the top-cover.

❈ While assembling the PCB, make sure the it is properlyfastened by the fastening hook of the control-panel. If not,the selection S/W will not work.

❈ Checkpoint after replacing the PCB-Ass’yCheck that each component works properly. (using the testmode)


6-2 Replacement of pressure-sensor, water-valve, checker-ass’y, ass’y-detergent

1) After removing the 2 screws that fasten the top-cover and thecover-T.C. together, gently push the cover-T.C. to the directionof the arrow in the figure to separate it.① Remove the 3 screws (2 on the rear, 1 on the front) that

fasten the top-cover and the out-case together, gentlyraise the rear side, and push it to the front in order to sep-arate the top-cover and to turn it over.

➁ Before turning over the top-cover, remove the screw thatfastens the earth-wire.

2) Pressure-sensorAfter pulling out the terminal of the pressure-sensor lead-wire,widen the hook to remove the sensor.

❈ While assembling the pressure-sensor, ensure that the air-hose is not kinked and connected properly.

3) Water-valveRemove the 3 terminals of the water-valve lead-wire. Thenremove the 3 screw-taps, TH that fasten the water-valve of theass’y-detergent inside the top-cover to disassemble the ass’ywater-valve.

❈ Before assembling the water-valve, ensure that the seal-detergent is not missing. (If the seal-detergent is missing,water leaking occurs and it may cause the danger of a short.)

4) To disassemble the ass’y-detergent, turn over the top-coverand remove the 2 screws.

5) After pulling out the terminal of the checker-S/W lead-wire,remove the 2 screws that fasten the checker-S/W.(Pull out the lead-wire terminal while pressing the hook.)

5. Troubleshooting

* Since the structure of the automatic microcomputer washer is complicated, you may make a service call even though the prob-lem is not caused by the defective product. This section easily explains how to diagnose such problems correctly and how torepair at lower cost.

5-1 Cautions in repairing or replacing

1) The static electricity on the plastic part of the washer or on your body may cause to damage the electronic components.Therefore, before working on the PCB, earth by your body or touch the terminal of the washer power plug and the earth wire inorder to remove the current difference between your body and the washer.

2) Since the components on the PCB are coated with the urethane, they cannot be checked by the test rod of the tester. Therefore,check them by carrying out the test mode in order to diagnose the problem according to the results.


When diagnosing the problem or replacing the part, please ensure that the following instructions are followed
