SOFTENER DISPENSER

This is the device to dispense the softener automatically by centrifugal force. This is installed inside the Balancer Ass'y.

FUNCTIONAL PRINCIPLE

1. Softener stays in room (A) when poured into softener inlet.

2. Softener in moved 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 in moved 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 MOVEMENT

AUTOMA TIC UNBALANCE ADJUSTMENT

This system is to prevent abnormal vibration during intermittent spin and spin process.

FUNCTIONAL PRINCIPLE

1. When the door 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 the serious vibration, and the spin process is interrupted.

3. In case that P.C.B. ASS'Y gets "OFF" signal from

the safety switch, spin process are stopped and rinse process is started automatically by P.C.B. ASS'Y.

4. If the safety switch is operated due to the

unbalance of the tub, the program is stopped and the alarm is given.

CIRCULA TING-W ATER COURSE AND LINT FILTER

CIRCULATING-WATER

The washing and rinsing effects have been improved by adopting the water system in which water in the tub is circulated in a designed pattern. When the pulsator rotates during the washing or rinsing process, the water below the pulsator vane creates a water currents as shown in figure.

LINT FILTER

Much lint may be obtained according to the kind of clothes to be washed and some of the lint may also stick to the clothes. To minimize this possibility a lint filter is provided on the upper part of the tub to filter the wash water as it is discharged from the water channel. It is good to use the lint filter during washing.

HOW TO CLEAN THE LINT FILTER

1. 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.

SYNCRONOUS MOTOR

STRUCTURE

FUNCTIONAL PRINCIPLE

1. When the SYNCRONOUS MOTOR connected to the power source the SYNCRONOUS MOTOR rotates 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, BUBBLE, PUMP, HOT WATER, COLD WATER)

1. CIRCUIT DIAGRAM AND EXPLANATION

• Controlling load of button input in MICOM terminal, it is selected to 'H' or 'L'. It is selected to 'L' in running load case and in 'H' case, load driving is finished. In clockwise rotation of washing motor, as MICOM No. 10 is changed 6V to 0V, TR (Q8, A1270Y) is turn on. And then, the TRIAC1 (SM12JZ47) is turn on, the source of electric power is supplyed to washing motor for clockwise rotation. The TRIAC, as switching element, force to 'ON' or 'OFF' by use of the Q8 (A1270Y). In the rest loads, when the MICOM terminal voltage changes 6V to 0V, each TRIAC DRIVE TR is active, and then the TRIAC switches the source of electric power to loads.

• The purpose of using the MICOM terminal No.3 Q15 (A1271Y) is that the Q15 prevents the instant supply of electric power 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. 10 is 'L', the Q8 (A1270Y) turn on and control the TRIAC. The resistance, as 62Ω& 1/2W, of the R21 is used to limit the GATE current of the TRIAC.

•The ceramic condenser C2 between the T1 and the GATE of the TRIAC is used for preventing the wrong action by means of the noise.

•The R1 (100Ω, 1W) and C1 (683K) between the T1 and T2 of the TRIAC is used for protecting the TRIAC, it is usually called SNUBBER CIRCUIT.

•The waveform of MICOM pin No. 1

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 the resistance between the TR E & C with tester, the resistance value should be near the ∞Ω. If not, the DRIVE TR is out of order.

• If the ceramic condenser (C2, C4, C6, C8, C10, C12, C14) using by protecting the noise between the GATE & T1 of each TRIAC has a short circuit, it has no voltage drop between the T1 and GATE. Therefore, the TRIAC is not turn on.

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 23.0 KHz of ‘HIGH’ in the MICOM terminal No. 38. 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. 38and 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

'LEVEL SENSING ERROR' (See page26). In case of proceeding the water supply continuously in 'HIGH' water level, it is

desirable to change the WATER LEVEL SENSOR 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.
