2. Main function of PCB program

2-1. LOAD SENSING

1) Deciding the water level

① Cotton, Whites, ECO course will be followed by this process.

② Check the water level with dry laundry at the starting wash.

③ Check the water level by using motor output data during 20 sec, 65 rpm.

2) Balancer Spin

① Check after finishing washing step with wet laundry.

② Checking by using motor output data during 20 sec, 65 rpm.

③ The decided data is different depending on loading condition.

2-2. BALANCE SPIN

1) Motor running during balance spin.

① Spreading the laundry : Rotating the same 45 rpm with left and right direction alternatively.

② Attaching stop : Attaching the laundry to drum inside with constant speed.

Unbalance checking point : First step, check the U.B at 95 rpm, 160 rpm.

Second step, check the U.B at 95 rpm, 350 rpm.

Third step, at 300 rpm. if the unbalance data is over the criterion,

This process will be repeated.

④ Drain step : Drain at water around 160 rpm.

⑤ After drain, check the unbalance data again. This is so-called balance spin step.

2) Property of balance spin.

① Conducting 10 times maximum.

② If the washer can not pass balance spin step during 10 times, then water will be supplied.

③ If the washer can not pass 20 times of balance spin, UE error mode will be displayed on PCB.

③

22

2-3. DOOR S/W

1) The working principle of Door S/W

① Door Locking

Bimetal on ( 3 sec) --> solenoid (supply 20msec pulse 2 times)

② Door Unlocking

Bimetal off --> solenoid (supply 20msec pulse, until unlock)

③ After door locking, all parts can work normally.

④ After pressing power button, if the temperature of wash thermistor is over 50 ℃ or the water level is over the safety level, the door will be locked.

⑥ The door the will be unlocked immediately after all processes are finished.

⑦ The door can be opened during processing if there is no problem to unlock.

23

2) DOOR OPEN SYSTEM

① If add the laundry during washing, press the door unlock button.

② Door open sequence at abnormal condition.

start / hold door unlock button, 2sec.ON

water level is less than safety level?

YES

Temperature is less than 50 ℃ ?

YES

Display <LOCK> off

NO

NO drain fan motor on/ cold water supply

Door open

24

2-4. Child Lock

① Press the TEMP ” DRY button simultaneously during processing.

② Under the Child Lock function, only power button is working.

③ During Child Lock function, CHL will be displayed on PCB.

④ In orden to unlock Child Lock mode, press "TEMP" and "DRY" simultaneously.

2-5. The sequence of drain

① If the checking time to reset point is below 1 min, the remaining drain time is 30 sec.

② If the checking time to reset point is over 1 min, the remaining drain time is 2 min.

③ If the checking time to reset point is over 10 min, OE singal will be appeared on PCB.

④ If the temperature is over 50 ℃ , the water will be supplied to high water level, then the drain will start.

25

3. Convenience service functions(test mode)

1. Testing Mode

PCB and other electronic parts will be tested without water supply whether they are normal or not.

1) Process : press power button --> press "SPIN" button 3 times with pressing "WASH" button --> 'L d' will be shown on LED --

> Whenever pressing "TEMP" button 1 time, below process will be occurred.

L C (Lock Closed) --> F ( Fan Motor) ---> H (Hot V/V) --> C (Cold V/V) ->

P (prewashing V/V) -> d ( dry V/V) -> bb (bubble) -> dr (drain motor) ->

L O(Lock S/W Open)

2) More details

① When turn on 'LOCK' singal, all process is conducting normaly.

② When working starts, the PCB displys all the sensor conditions.

③ In this case, BLDC Motor is not tested. In order to test it, select spin or rinse.

2. Continous testing mode

1) Process : after pressing "WASH", "RINSE", "SPIN" button simultaniously, press "POWER" button.

ALL LED On/Off 1 time --> L C (Lock Closed) ---> R (Motor right) --> L (Motor Left) --> F ( Fan Motor) ---> H

(Hot V/V) --> C (Cold V/V) --> b (pre-wash V/V)

--> d ( dry V/V) --> bb (bubble) --> h1 (HEATER WASH)--> h2(HEATER DRY) --> dr (DRAIN MOTOR On) --

>L O(Lock S/W Open)

2) More tails

① LED test can be done with all LED On.

② All sensor conditions will be shown on PCB during processing.

5) TROUBLE SHOOTING OF DRY SYSTEM

◈

HEATER DRY

Function : heating the air during dry

◎ FAILURE MODE : ＊ "H7" - The air cannot be heated to 10 ℃ during 2 min.

◎ CHECKING METHOD : ＊ Check the resistance of heater coil and replace with new one.

◈

Thermistor

Function : sensing the air temperature.

◎ FAILURE MODE : ＊ The air cannot be heated even though water is supplied.

＊ "H1" - shot or cut-off

＊ "H3" - air temp. is reached over 150 ℃

◎ CHECKING METHOD : ＊ Check the resistance of thermistor, replace with new one.

◈

FUSE TEMPERATURE

function : protecting from the fine hazard or overheating, if the temp., rises over 128 ℃ , power supply will be cut-off.

◎ FAILURE MODE : Dry is not performed.

◎ CHECKING METHOD : Check if fuse is short, and replace with new one.

SWITCH THERMOSTAT(BIMETAL)

function : control the duct as remperature, if the temp reached over 150 ℃ , all power supply will be cut. and if the temp go down

120 ℃ the power will be ON.

protecting overheating by cutting off heater power supply if the temperature rises over 150 ℃ , and reoperating heater by connecting heater power supply if the temperature falls under 120 ℃ .

6) FAR-INFRARED COATING

function : steilization with radiating far- infra red, by means of ceremic coating.

increasing the dry efficiency and effecting sterilization by radiating far infra-red ray from ceramic particle coating on DUCT

The far infrared ray is emitted from the ceramic coating, comes into drum by radiation and reflection, and penetrates deeply into laundry with the effective moisture removal and sterilization.

7) LACK OF DRY PERFORMANCE

◎ Situation : after drying, the clothes still get wet.

cause) ☞ The laurdry amount is more than the recommendation capacity 7.0kg.

☞ Condensing cold water is not supplied.

☞ Clogging Bellows Duct results in poor air circulation.

2. Operating Sequence

DRAIN MOTOR connects drain passage by pulling LINK VALVE DRAIN. If the DRAIN MOTOR stops working,

LINK VALVE DRAIN returns to initial state by spring.

3. Check point when connecting hose drain O

① Keep the hose straight.

② Keep the end of hose not to dip in water.

4. Checking Methods

◎ Situation : ＊ "OE" is shown on PCB.

＊ Not finishing drain during 10 min.

＊ The water level can not reach to RESET POINT during 10 min of drain.

Checking Methods

＊ Check the hose drain O condition; twisted or frozen.

Replacing methods

＊ replace HOSE DRAIN O

＊ clean the inside of COVER VALVE.

＊ Check the hose drain O condition, blocked.

＊ replace DRAIN MOTOR disassemble COVER
