AUTOMATIC 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.

CIRCULATING-WATER 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.

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.

• 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.

• 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

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.

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.

2. EXPLANATION OF CIRCUIT
• The RESET unit is a hardware circuit, of which all programs are initialized, when the power switch is 'ON'. Here, the
reason why uses RESET I.C. is that the RESET UNIT prevents the MICOM from incorrect action. Also, the R37 & C19
(104Z), as a RC filter, is used in order to absorb the noise.
• The waveform measurement of the part ! with being 'ON' the power switch.

2. EXPLANATION OF CIRCUIT
• The MICOM terminal No. 13 gets into 'L' at the state of the closed door. If the door is opened in spining stage, the
MICOM generates error signal. (See page 27)
• 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 400
mSEC: It is regarded that the door should be open. Therefore it is displayed as door open error. (See page 27)
3. CAUTION FOR A/S
• Be level with the ground.
• The UNBLANCE error occurs in case of not being level with the ground.
• The waveform between the MICOM terminal No. 13 and the GND.

2. EXPLANATION OF CIRCUIT
• Detecting the voltage of running condenser, it sends the sensing data to the MICOM terminal No.35 & 36. That is, as
charging & discharging time of running condenser becomes different according to the loads, in fuzzy course the
washing time is determined by sensing the quantity of washing clothes.
• The waveform between the part of ! and the GND (waveform of pulse)
