FEATURE OF THE WASHING MACHINE1) The first air bubble washing system in the world.2) Quiet washing through the innovational low-noise design.3) The wash effectiveness in much more enhanced because of the air bubble washing system.4) The laundry detergent dissolves well in water because of the air bubble washing system.5) The adoption of the water currents to adjust the unbalanced load.6) One-touch operation system.
WATER CURRENT TO ADJUST THE UNBALANCED LOADIt is a function to prevent eccentricity of the clothes after wash by rotating pulsator C.W and C.C.W for 20 seconds. (But,the DRY & SILK course have no operation of the water currents to adjust the unbalanced load.)
EFFECTIt reduces vibration and noise effectively while spinning.
WATER FLOW
FUNCTION FOR SOAK WASH
DISPLAY THE RESIDUAL TIMEWhen the SOAK WASH is selected, the total wash time increases because 30 minutes for soak process are added to thetime of main process.
PROGRESS
NOTE: ‘ I ’ mark indicates the operation of the water currents to adjust the unbalanced load.
AUTOMATIC WATER SUPPLY SYSTEM FOR BLANKET WASHThe water level would be lowered because the blanket absorbs water at the beginning of washing. Therefore, after 30seconds, the operation is interrupted to check the water level, and then the water is supplied again until the selected waterlevel is reached.

PULSATOR SYSTEMWhen the new shaped pulsator is rotated C.W or C.C.W at a high speed, it makes the 'heart-shaped' water currents asshown below.
AUTOMATIC DRAINING TIME ADJUSTMENTThis system adjusts the draining time automatically according to the draining condition.
FUNCTIONAL PRINCIPLE1) The micom can remember the time from the beginning of drain to reset point when the pressure switch reaches to
"OFF" point.
2) In case of continuous draining, residual drain time is determined by micom.Draining time as a whole=D + 60

SOFTENER DISPENSERThis is the device to dispense the softener automatically by centrifugal force.This is installed inside the auto-balancer.
FUNCTIONAL PRINCIPLE1) Softener stays in room (A) when poured into softener inlet.2) Softener moves from (A) to (B) by centrifugal force during intermittent spin process.3) Softener flows from (B) to (C) during rinse process next to intermittent spin.4) Softener moves from (C) to (D) by centrifugal force during second intermittent spin.
After spin process is finished, the softener is added into the tub through softener outlet.
FLOW OF THE SOFTENER
FLOW OF THE SOFTENER INSIDE OF THE BALANCER
NOTE: Softener moves into the next room when r.p.m. of the tub is more than 100 r.p.m.
HOW TO CHECK MOVEMENTPour a reasonable amount of "MILK" into softenerdispenser and operate the washer with no load. In finalrinse cycle, make sure that the milk is added into thetub through softener outlet.

AUTOMATIC UNBALANCE ADJUSTMENTThis system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE1) When the lid is closed, the safety switch contact
is "ON" position.2) In case that wash loads get uneven during spin,
the outer tub hits the safety switch due to theserious vibration, and the spin process isinterrupted.
3) In case that P.C.B. ASS'Y gets "OFF" signal fromthe safety switch, spin process are stopped andrinse process is started automatically by P.C.B.ASS'Y.
4) If the safety switch is operated due to theunbalance of the tub, the program is stopped andthe alarm is given.
CIRCULATING-WATER COURSE AND LINT FILTERCIRCULATING-WATERThe washing and rinsing effects have beenimproved by adopting the water system in whichwater in the tub is circulated in a designed pattern.When the pulsator rotates during the washing orrinsing process, the water below the pulsator vanescreates a water currents as shown in figure.The water is then discharged from the upper part ofthe tub through the water channel.About 40L/min. water is circulated at the 'high'water level, standard wash load and standard watercurrents.

LINT FILTERMuch lint may be obtained according to the kind ofclothes to be washed and some of the lint may alsosticks to the clothes.To minimize this possibility a lint filter is provided on theupper part of the tub to filter the wash water as it isdischarged from the water channel. It is good to usethe lint filter during washing.
HOW TO CLEAN THE LINT FILTER1) Pull the filter frame upward.2) Turn the lint filter inside out, and wash the lint off with water.3) Return the filter as it was, and fix the filter frame to the slot.
RESIDUAL TIME DISPLAY When the START/HOLD button is pressed, the residual time (min.) is displayed on the time indicator, and it will be counteddown according to the process.When operation is finished, the TIME INDICATOR will light up .
DRAIN MOTORSTRUCTURE
FUNCTIONAL PRINCIPLE1) When the DRAIN MOTOR connected to the power source (AC 220V), the DRAIN MOTOR rotates with 900 r.p.m and
revolves the pulley by gear assembly for reducing.2) When the pulley is rotated, the pulley winds the wire to open the drain valve.3) Therefore, rotation of pulley is changed to the linear moving of wire.4) The wire pulls the brake lever of Gear Mechanism Ass'y within 5 seconds.5) After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation of the lever.6) When the power is turned off, the drain valve is closed because the wire returns to original position.

LOAD DRIVE UNIT(CW WASH, CCW WASH, DRAINAGE, HOT WATER, COLD WATER, BUBBLE, AUTO OFF)
1) CIRCUIT DIAGRAM AND EXPLANATION
• Controlling load of button input in MICOM terminal, it is selected to ‘L’ or ‘H’. It is selected to ‘H’ in running load case andin ‘L’ case, load driving is finished. In clockwise rotation of washing motor, as MICOM No. 31 is changed 0V to 5.4V,TR(Q14, C3202Y) is turn on. And then, the TRIAC1(SM12JZ47) is turn on, the source of electric power is supplyed towashing motor for clockwise rotation. The TRIAC, as switching element, force to ‘ON’ or ‘OFF’ by use of theQ14(C3202Y). In the rest loads, when the MICOM terminal voltage changes 0V to 5.4V, each TRIAC DRIVE TR is active,and then TRIAC switches the source of electric power to loads.
• The purpose of using the MICOM terminal No. 6 Q15(A1271Y) is that the Q15 prevents the instant supply of electricpower supply to loads, in case MICOM's action is wrong by means of pushing initial power switch.

2) DETAIL EXPLANATION OF CIRCUIT ACTION (ACTION OF CW WASH)
•In case MICOM terminal No. 31 is ‘H’ and No. 6 is ‘L’, Q14(C3202Y) & Q15 (A1271Y) turn on and control the TRIAC. Theresistance, as 62 Ω & 1/2W, of R52 is used to limit the GATE current of the TRIAC.
•The resistance R38 (3.9KΩ, 1/4W) and R45 (1KΩ, 1/4W) control the base current of Q14 & Q15 in order as TR forces toturn on sufficiently.
•The ceramic condenser C29 between T1 and the GATE of the TRIAC is used for preventing the wrong action by means ofthe noise.
•The R63 (100Ω, 1W) and C28 (683K) between the T1 and T2 of the TRIAC is used for protecting the TRIAC, it is usuallycalled SNUBBER CIRCUIT.

3) CAUTION AND CHECKING FOR A/S
•If load is active as soon as the power switch is ‘ON’, check the driving TRIAC of load.
•Check the MICOM output terminal, if the load doesn't act although the TRIAC isn't anything wrong.
•Sometimes it is happened that the TRIAC DRIVE TR has a short circuit or an open circuit. In this case, being measured theresistance between the TR E & C with tester, the resistance value should be near the oo Ω. If not, the DRIVE TR is out oforder.
•If the ceramic condenser (C17, C19, C20, C23, C24, C26, C29) using by protecting the noise between the GATE & T1 ofeach TRIAC has a short circuit, it has no voltage drop between the T1 and GATE. Therefore, the TRIAC is not turn on.
•If MICOM terminal No. 6 is not active from 5.4V to 0V, all DRIVE TR of the TRIAC are not turn on. Therefore, if the TRIAC isout of order, to begin with, check the MICOM terminal No. 6 and TR Q15(A1271) necessarily.

WATER LEVEL SENSOR UNIT1) CIRCUIT DIAGRAM
2) EXPLANATION OF CIRCUIT• Push the power switch. And, in order to carry on the action of course selection, input the selection of frequency
according to each water level selection.• The frequency of water level sensor in each water level becomes square wave and is sended to the MICOM.
If the water level is selected ‘HIGH’ in washing, water supply proceeds until inputing the frequency 22.70 KHz of ‘HIGH’ inthe MICOM terminal No. 24. Being finished the water supply, washing process is proceeded. After the washing process,water level reaches to RESET point, and then after the (D)+ 60 seconds, the spin process begins.
• The value of the frequency between the MICOM terminal No. 24 and the GND.
3) CAUTION FOR A/S• The output of the frequency in the WATER LEVEL SENSOR varies in accordance with temperature and using condition.
If it doesn’t input the output of the WATER LEVEL SENSOR in the MICOM, the error message is displayed as ‘E9’. Incase of proceeding the water supply continuously in ‘HIGH’ water level, it is desirable to change the WATER LEVELSENSOR because of the defect in the WATER LEVEL SENSOR.
• Check the TR Q4(A1270Y).• Being checked with tester, the value of the voltage reaches about 4V.• As the frequency is lower, the water level is higher.
2) EXPLANATION OF CIRCUIT• The primary voitage of the transformer sets 220V, the secondary voltage of the transformer is full wave rectified by use

• Part of the button scan
The system of the BUTTON SCAN is in wide use for the method of the DUTY output part in L. E. D DRIVE yet here. It is inuse for the method of the segmental output.
• Though the period of the DUTY part is 1/9, the last 9th part does not generate the waveform and checks the button inputwith getting out the segmental output at the same time.
• RA1 (473J, 47KΩ) is a ‘PULL DOWN’ resistance for preventing floating action.• D15 prevents the L. E. D from turning on unnecessarily with forming the closed loop like a threaden line at the time of
button push.

2) EXPLANATION OF CIRCUIT• As the OSCILLATION UNIT is a basic part of the MICOM DRIVE. If the oscillation doesn’t generate, we are able to
It is in general use for the MICOM maker’s recommendatory value of condenser which is fit for MICOM’s characteristics.
• The R82(18MΩ, 1/4W) is in use to get rid of the initial abnormal oscillatory phenomenon of the 32.768 KHz crystaloscillator.
SAFETY SWITCH UNIT1) CIRCUIT DIAGRAM
2) EXPLANATION OF CIRCUIT• The MICOM terminal No. 63 gets into 'L' at the state of the closed lid. If the lid is opened in spining stage, the MICOM
generates error signal as 'LE'.• Case of range 40 mSEC~300 mSEC in spining time: It is regarded that washing clothes should be inclined.
Accordingly washing time increases 8 minutes and rinsing action takes place another one time. Case of above 400mSEC: It is regarded that the lid should be open. Therefore it is displayed as 'LE'.
3) CAUTION FOR A/S• Be level with the ground.• The 'UE' error occurs in case of not being level with the ground.• The waveform between the MICOM terminal No. 63 and the GND.
LOAD SENSOR UNIT1) CIRCUIT DIAGRAM
2) EXPLANATION OF CIRCUIT• After TRIAC is off, RUNNING CONDENSOR discharges the voltage charged in it and sinwave is generated at this time.
MICOM starts to check every 0.224ms the time from 2nd falling edge to 3rd falling edge. Photo coupler (IC4) of PCBconverts the sinwave into clock pulse (times X 0.224ms) and send it to MICOM terminal No. 22 & 23. MICOM checksthe clock pulse and counts the periodic time and judges the water level after comparing with data which is alreadymemorized in the MICOM.

DISPLAY UNIT
1) CIRCUIT DIAGRAM
2) EXPLANATION OF CIRCUIT• The MICOM terminal No. 33~40 amplifies the source current to produce the 'H' by use of the buffer UDN-2981A. And
the MICOM terminal No. 43~54 sufficiently amplifies the sink current by use of the DRIVE I.C. ULN-2004A.• The waveform between the part of ! and the GND (part of the DUTY).
The division rate of the DUTY is 1/9. And as part of the DUTY treats the black time between the square waves, itprevents the phenomenon of faint lighting of L.E.D unnecessarily due to the phenomenon of fold in delay time of the IC8 between the input and the output.
• The equivalent circuit of DRIVE IC & BUFFER IC.
• If the light of the DISPLAY unit is does not appear, check the circuit using the oscilloscope.
