ABNORMALCONDITION
When the washer is abnormal, the washer stops as the every actions turns off, beep tone
sounds ON-0.1 second and OFF-0.1 second for 6 seconds and number window LED display
abnormal code. The washer judges the following six conditions as abnormal condition.
1) Abnormal condition of water supply
In supplying with water, the water level does not reach extra low level within 10 minutes or
does not reach your chosen water level within 20 minutes.
The number window LED display abnormal code: and the electric buzzer sounds to
indicate a problem at the same time.
2) Abnormal condition of drain
In draining, the water level does not go down below the reset level of the water level sensor
within 8 minutes.
The number window LED display abnormal code: and the electric buzzer sounds to
indicate a problem at the same time.
3) Abnormal condition of spin-dry
•The safety switch works 3 times continuously during the program of rinse-spin or works 1
time in the single program of spin-dry.
The number window LED display abnormal code: and the electric buzzer sounds to
indicate a problem at the same time.
•The washer lid is opened.
The number window LED display abnormal code: and the electric buzzer sounds to
indicate a problem at the same time.
4) Abnormal condition of child lock.

• Check whether the computer board functions normally.
10)Over-voltage fault
The digital tube displays the fault code " ", accompanied by a whistle sound
• First detect whether the user's home voltage is too high
• Check whether the computer board function is normal
11)Low voltage fault
The digital tube displays the fault code " ", accompanied by a whistle sound
• First check whether the user's home voltage is too low
• Check whether the computer board function is normal
12) Abnormal motor operation failure
The digital tube displays the fault code " ", accompanied by a whistle sound
• Check whether the motor wiring harness is good
• Check whether the computer main control board function is normal
13)Excessive leakage current detection fault
The digital tube displays the fault code " ", accompanied by a whistle sound。
• Replace the computer main control board
14)IPM hardware abnormal failure
The digital tube displays the fault code " ", accompanied by a whistle sound
• Replace the computer main control board

15) Water temperature sensor failure EC2
The digital tube displays the fault code "EC2"
• First check whether the connection between the main control board and the water temperature
sensor is good
• Replace the heating tube or the computer main control board to test whether the function is
normal
16)Heating pipe failure E6C or E7C
The digital tube displays the fault code "E6C" or "E7C"
• First check whether the connection between the main control board and the heating tube is
good，Measure whether the heating tube resistance is in the normal range
• Replace the heating tube to test whether the function is normal
17) Door lock failure U4
The digital tube displays the fault code "U4"
• First check whether the connection between the main control board and the door lock is good
Is the door sensor in the normal position
• Replace the door lock to test whether the function is normal

Operation of safety device
When the safety device works by abnormal swing of spin drum, machine works automatically to
stop Spin-Dry cycle and operates water supply valve to pour water into the Wash/Spin Tub and
then starts washing cycle for replacing washing clothes evenly.
After above operation has down twice, if safety device works again, machine will stop, and the
number window LED display abnormal code: and begin blinking on and off at the same time
and the electric buzzer sounds to indicate a problem.
•Open the Wash Lid and rearrange the clothes evenly around the Wash/Spin Tub.
•Close the Wash Lid and press the START/PAUSE button again.
