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 short-
circuited), 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 short-
circuited), 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. But if it is detected more than 7 times, this error will
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
failed more than 32 times, this error will occur. (caused by
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.
