Where, what & how to check?

Result of Check Possible Cause How to repair & settle

1. It is mostly caused by noise from

mains or transfomerient power cut.

1. Check whether power is

automatically turned off when

turning on the AUTO OFF switch

after unplugging the power cord from

the outlet

2. It would be defect of the controller if 

power is automatically turned off 

immediately when turning on the 

power switch even though there is 

no defects in the AUTO OFF switch.

Automatically

turned off

Defect in main.

Mechanical defect

of the AUTO OFF 

switch.

Explain the cause. 

(It happens specially 

when a high frequency 

equipment is a used 

around the washer or in 

the case voltage 

fluctuation is big)

Change the AUTO OFF

switch.

Change the controller.

How to repair and settle

• If the value is not within 1~26 by

checking  the controller group.

Recalibrate or replace the

controller.

• When checking the value of the

electrode sensor by Test mode during

the operation (washing, rinsing, spinning

etc.) of the washing machine, the sensed

value has no change.

Check the harness, 

clean the electrode of sensor

Stop the sensor working*

• Temperature sensor fault : “       ” displayed

Check the operation of temperature sensor

by the QC test mode.

*Stop/Reset the sensor: Stop or reset the sensor by entering Test mode.

Change the sensor or

controller 

Check the Harness 

• The difference between the sensing value

measured from the supplied water by a jig and

the sensor value of the product is 5 or more..

Change the sensor, 

clean the electrode of sensor

Stop the sensor working*

**

- If a user wants to detect a Detergent more than the current one

: Increase the group value (by 1~2 step)

- If a user wants to detect a Detergent less than the current one

: Decrease the group value (by 1~2 step)

Turn the power switch on by pressing WATER LEVEL+STAIN LEVEL+RESERVATION button together.

Test mode : Only I-SENSOR LED is on and display shows current sensing mode

: temperature &  conductivity sensing is disabled

: temperature sensing is enabled, but conductivity is disabled.

: temperature &  conductivity sensing is enabled

1. Press WATER LEVEL BUTTON once:       

Press WATER LEVEL BUTTON again : power off

2. Press RINSE BUTTON once: 

Press RINSE BUTTON again : power off

3. Press START/PAUSE BUTTON once:  

Press START/PAUSE BUTTON again : power off

Turn the power switch on by pressing WATER LEVEL + PROGRAM and STAIN LEVEL button together.

Initial Test mode display : All LEDs are off,except I-SENSOR LED

Display the number of TR calibration times : Display “      ” means not calibrated, “     ” for the 

first time and so on.

1. Press Program button once: Display the current Controller Group (1~26)

Program button again : Decrease the controller group by one (display the changed group)

Program button to decrease by one

2. Press START/PAUSE button once : Display the current Controller Group (1~26)  

Press START/PAUSE button again : increase the controller group by one (display the changed group)

START/PAUSE button to increase by one

The buzzer sounds if there is no controller group.

Initial operation: Press "RESERVATION" + "START/PAUSE" botton together after power on, and  press
"RESERVATION" button only again
(displaying the number of pressing button and each data every 0.5 second)

Sensor

Terminal

of Controller

• Loosening the front panel of the washing machine

and connect the sensor connecting terminal with

the terminal of the jig.

After supplying water to the washing bath, agitate

for one minute before using the jig.

Record the sensed value of the sensor attached

to the current product at Test mode.

Connect the jig, put the jig sensor into the

washing bath, and record the sensed value of the

sensor.

Determine the sensor performance by comparing

the value measured by the jig and the value

measured by the sensor attached to the product.

1 times : TR Controller Group ( 1 ~ 26 )

2 times : Check the temperature sensor codition

0  : Normal

99 : Temperature senosr’s error,

3 times : Temperature of supplied water

4 times : Increment/decrement of washing time according to temperature

5 times : Washing stream at Motor off according to temperature

6 times : The number of comparing the conductivity of washing with rinsing conductvity
