Part Display Criteria
The error code is displayed when the
error AC Input Voltage is too high.
The error code is displayed when the
error compressor has failed to start.
The error code is displayed when
the compressor IPM fault error has
occurred.
This error code is displayed when an
abnormal current is detected in the
compressor.
The error code is displayed when the
compressor motor is constrained.
The error code is displayed when the
error AC Input Voltage is too low.
The error code is displayed when the
error AC Input Voltage is too high.
Display error when open error is
detected by sparkling tank overflow :
separation of Sparkling Tank Overflow
Overflow
Sensor housing part, contact error,
disconnection, short circuit.
Display error when open error is
detected by water supply to sparkling
tank error : seperation of Sparkling Tank
Water Level Sensor housing part, contact
error, disconnection, short circuit.
To check if the part is normal
Check the input voltage. (This error occurs when the
input voltage is AC 310V or higher.)
Check the soldering status of the inverter PCB. (Check
if any parts have short-circuited). Check if the DC 15V
output is less than 13.5V. Check the Comp and Cycle.
Check the compressor wire connections. Check the
soldering status of the inverter PCB. (Check if any parts
have short-circuited). Check the Comp and Cycle.
Check if the compressor and the Cycle is normal.
Check the input voltage. Check the soldering of
the inverter PCB. (Check if any parts have short-
circuited.)
Check the input voltage. (This error occurs when the
input voltage is AC 106 V or lower.)
Check the input voltage. (This error occurs when the
input voltage is AC 310V or higher.)
