If higher than 32kHz or lower than 10kHz of water level sensor frequency is continuously kept for 4sec in every

0.5sec measurement, this error will occur. (caused by wire-breaking of water level sensor)

If AD converter data in water temp sensor become larger than 63,000 (in case of the temp. sensor being open) or less than 2,000 (in case of the sensor being short-circuited), this error will occur.

If AD converter data in fan-housing temp sensor become larger than 63,000 (in case of the temp. sensor being open) or less than 2,000 (in case of the sensor being shortcircuited), this error will occur.

If AD converter data in drying-duct temp sensor become larger than 63,000 (in case of the temp. sensor being open) or less than 2,000 (in case of the sensor being shortcircuited), this error will occur.

In case that position detection signal was not detected longer than a unit set time during the motor starting and driving, it will be retried 5 times. If it is not detected more than 6 times, this error will occur. (caused by wire-breaking of haul-sensor and motor, or by restriction of motor driving.)

If an excessive current is detected at IPM, it will be retried 6 times.Butifitisdetectedmorethan7times,thiserrorwill occur. (caused by short-circuit of motor wire)

If motor rotates in reverse direction during the motor starting and driving or abnormal signal is detected at haul sensor, it will be retried 8 times. But if it is detected more than 9 times, this error will occur. (caused by motor overload or noise)

If 8 times retrial of motor positioning is failed during the early time of motor driving, it will be retried continuously. But if it is failedmorethan32times,thiserrorwilloccur.(causedby wrong connection of haul sensor or motor wire)

If more than 450V of instant voltage is detected at DC Link, this error will occur. (caused by an electric failure during the high-speed dehydration) Appearance: IPM Low Arm Short Break

In case that there is no AC power signal for longer than 60mSec, or that less than 125V of DC Link average voltage is detected, or that less than 175V is detected during the PHI error, this error will occur. (caused by instant electric failure or wire break of power cord) Appearance: Motor-generating current will be charged through IPM All Open Break.

If both AC power signal and DC link voltage are normal, this

error will be released and proceed the previous operation.

Excessive water level/water leakage

Fan motor abnormal

Water Feed abnormal

Water Drain abnormal

If AC power signal is detected for longer than 4sec even after

18E

connection of power plug or after opening of the relay by power off, this error will occur.

If power switch is continuously being pressed for 12sec after

12E

power-on, this error will occur.

If a button on the control panel is continuously being pressed

14E

for 30sec.

If there is no press of any button for 10min after power-on or

8888

changing course before entering an operation, this error will occur.

If door is open for longer than 1sec at the time of entering or

during an operation, this error will occur.

If the lock or unlock function of door doesn't work after 3time of

dE1

trial, this error will occur.

This error occurs to protect a coil in the locking apparatus

dE2

against frequent usage of lock and unlock function of door.

If a communication to MCU on the control panel is abnormal for longer than 2sec, it functions to reset MCU to 20mSec and to

13E

retry the communication. Abnormal communication for longer than 6sec will make this error.

If less than 20.48kHz of frequency of water level sensor is continuously kept longer than 10sec, this error will occur. (caused by abnormal increase of water level due to breakdown

of feed valve) Appearance: It functions to operate drain pump to the frequency level of 23.30kHz in 20sec-On/4sec-Off.

If higher than 24.70kHz of frequency of water level sensor

11E

during washing and rinse, this error will occur. (caused by water leakage at pump, hose, drum tub, etc.)

If excessive current signal due to restriction of fan motor is

detected for longer than 40sec, this error will occur.

If the feed water for washing or rinse doesn't reach the terminal

level of water supply after 20min, this error will occur.

If higher than 70°C is continuously detected for longer than

4Ed

8sec at temperature sensor of drying duct during drying, this error will occur.

If higher than 50°C of water temperature is detected at the time of water feed after selection of WOOL and LINGERIE

COURSES, this error functions to prevent damage from such a high water temperature.

If the water level frequency doesn't reach 24.70kHz after 15min during the water drain, or if the water level frequency of less

than 23.84kHz is detected for longer than 20sec during dehydration or drying, this error will occur. (caused by foreign matters in the drain pump or the breakdown)

Unplug the power plug, and PCB needs to repair.

Power Off

No pressing of a button longer than 1sec will release this error.

Power will be automatically off after 5sec.

Close the door and press START button again.

Power Off

Automatically released after 25sec.

If there is no abnormal communication for longer than 1sec,itis automatically released.
