5. General Error Function

SAMSUNG ELECTRONICS CO., LTD 7

•· 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 interval 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

- In case the water level frequency is 25.3KHz 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.

- Display shows ‘E2’.

3. OVER-FLOW ERROR

- Over-Flow error occurs when the water level is in abnormal operation (OVER-FLOW: 22.40KHz/50ß§ or more). 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 KHz is detected.

- Display shows ‘E3’.

4. DOOR OPEN ERROR

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

- Display shows ‘door’.

5. UNBALANCE ERROR

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

- Display shows ‘E4’.

6. WATER HEATER ERROR

- In case the water temperature varies by 40°C or more in 5 min, or by 2°C or less in 10 min after heating is started.

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

- Display shows ‘E5,E6’.

7. ASS’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, perform the time-drain for 3 min and then turn off the water drain pump. Then the display shows ‘E7’ as 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°C or more in the delicate course, and 40°C or more in the wool course.

- 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 ‘E8’.

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