Caution for safety during servicing

1. Do not allow the customer to repair the product.

The person may be injured or the product life may be shortened..

2. Execute A/S after unplugging the power supply unit.

Be careful of electric shocks.

3. Do not plug several plugs in the same outlet.

It may cause the fire due to overheat.

4. Check for damage, pressing or burning of the power plug or outlet.

Replace it promptly if it has a problem.(It may cause electric shocks or fire)

5. Do not clean the main body with water.

It may cause electric shocks and fire and shorten the product life.

6. The wiring of the harness shall be free from moisture and tightened during serving.

It shall not be deviated by certain impact.

7. Remove any dust or filth on the housing section,wiring section,connection section during servicing.

Protect from the possible cause of fire such as tracking,shortage etc.

8. Check for any mark of moisture on the electrical parts, harness section etc.

Replace the parts or remove the moisture..

9. Check the assembly status of the parts after servicing.

Maintain the status before servicing..

10. Pull out the power cord by holding the plug.

Be careful of electric shocks and fire when the cord is damaged.

11. Unplug the power plug from the outlet when the washing machine is not used.

Be careful of electric shocks and fire due to the strike of lightning.

12. Do not use or store sprays or flammable materials(including gasoline,alcohol etc.) around the
washing machine.

Be careful of explosion or fire due to electric sparks.

13. Do not put a bowl of water or wet laundry on the washing machine.

If the water has penetrated into the washing machine, this may cause electric shocks or fire.

14. Do not install the washing machine where it is exposed to bad weather.

It may cause electric shocks and fire and shorten the product life.

15. Do not push the control buttons with the aw l, pin, or sharp materials.

It may cause electric shocks and damage.

16. Check that the washing machine is leveled horizontally and installed properly on the floor.

The vibration may shorten the product life..

17. Joint the wire by the connector correctly.

When the wire is jointed by tape, this may cause fire due to tracking.

18. When the washing machine is to be laid for service, put the pad on the floor and la y the product on
its side slowly.

If the washing machine is laid on its front, the relay may be damaged by the tub.

19. When the wash-heater is replaced, check it is inserted in the bracket-heater and screw the nut.

If the wash is not inserted in the bracket-heater properly, this may cause the noise and
leakage since it is contacted to the drum.

4. General Error Function

•

When an error occurs, this function starts to keep generating error melody sounds and displays error indicators

as shown in the followings per corresponding error by blinking in 0.5sec intervals until the error status is completely

cleared out. In this case, all the driving devices are turned off until the error is cleared out.

1. WATER SUPPLY ERROR

- Water Supply Error occurs when water level frequency does not show changes more than 50Hz or water is not supplied up

to the water level presetting for 20 min or more at the time of initial water supply, the error status can be cleared by turning
POWER S/W OFF and resuming the POWER ON initial status.

- Display shows 'E1'.

2. WATER DRAIN ERROR

- Display shows ëE2í.

- In case the water level frequency is 25.5KHz or less in the initial phase of UNB-detecting cycle.

- Water Drain error can be cleared by turning POWER S/W OFF and resuming the POWER ON initial status.

3. OVER-FLOW ERROR

- Display shows ëE3í.

- Over-Flow error occurs when the water level is in abnormal operation. It can be cleared by turning POWER S/W OFF.
Water is drained prior to POWER S/W OFF and it is forced to be drained for 2 min if a frequency of more than 25.24
KHzisdetected.

4. DOOR OPEN ERROR

- Display shows ëdEí

- Door Open error can be cleared by closing the door.

5. UNBALANCE ERROR

- Display shows ëE4í.

- Unbalance error is cleared by POWER S/W OFF and by resuming the POWER ON initial status.

6.WATERHEATERERROR

- Display shows ëE5,E6í.

- In case the water temperature rises by 40°C or more in 5 min. or by 2°C l ess in 10 min after heating is started.

- It can be cleared by turning POWER S/W OFF.

7. ASSí Y PRESSURE S/W ERROR

* Generated Frequency Signal of WATER LEVEL(W/L) S/W (KHz)

- If the same signal as the above table is detected for more than 5 seconds, it is a PRESSURE S/W Error.

- When the error occurs, water drain pump will operate for 3 min. and then turn off the water drain pump.
Then the display shows ëE7í indicating a pressure s/w error indicator.

8. ABNORMAL WATER TEMPERATURE ERROR

- In case the water temperature is 60°C or more in the synthetic course, 50°Cormoreinthedelicate

- At the time of initial water supply, if the water temperature is not appropriate, water starts to be drained

and it is forced to be drained for 2 min when the abnormal frequency of 25.24KHz is detected.

- Display shows ëE8í.

- This error can be cleared by POWER S/W OFF.
