1. Cotton Course is for all cooton clothes such as towel, diaper and the same course as

Normal Steam Course.

2. At the Steam Washing, Washing Time is 30min for Heavy Stain, and 20 min for the other course.

3. Finishing Washing is the heating stroke to be reached up to Wash Temp, and if Wash

Temp. of Washing is 30-40°C, time is 5min, and if 60°C, time is 10min, if 95°C, time is

30min.

24

2. Main function of PCB program

2-1. LOAD SENSING

1) Deciding the water level

1

Cotton, Whites, ECO-White 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) Deciding Spin Starting Step.

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.

3

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.

25

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°C or the water level is over the safety level, the door will be locked.

6

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

7

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

26

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°C?

YES

Display <LOCK> off

NO

NO drain fan motor on/ cold water supply

Door open

27

2-4. Child Lock

1

Press the “TEMP”. and “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 order 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°C, the water will be supplied to high water level, then the drain will start.

28

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' signal, all process is conducting normaly.

2

When working starts, the PCB displays 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.

Checking Point

Keep the Packing from seperating (Hold Packing when replacing)

Keep the Packing from folding

Check the sealing between Duct Pipe & Duct B AS

Use only screw M4*8 for fixing Inlet Valve

Keep the sealing condition of Tub O tightly

Check the assembling order between INLET BOX & Hose A,C :

Pre Wash-Cold

Unfastening the nut for fixing earth first then unfasten the nut for fixing heater

At assembling the heater dry, check if the assembling condition between fixture heater is tight.(little gap on left & right)

At fastening the nut for fixing the heater wash, keep the protrusion length of bolt to 10~12mm.

(if under 10mm, water can leak, and if over 12mm, fixture heater can deform)

Thermistor Wash Unfasten the Nut for fixing heater, replace the thermistor, and fasten the nut for fixing heater

At fastening screw for fixing Door AS, be careful so that scratching at the related parts does not happen

: If the scratching happens, it is possible to be claimed about

Door As

MOTOR AS appearance damage

Be careful about the up/down direction of Door Glass : Keep the indication point of the part code downward.

To avoid the injury on the hand, grip the rim of the rotor

At initiating the assembling operation of the stator, grip the stator and fasten the screw; at unfastening the screw, grip the stator so that it does not fall.
