When checking the FAN MOTOR and/or the PUMP, disconnect the power supply completely before touching their terminals or
connectors.
If an open circuit is detected by the drain temperature sensor, the error is displayed 10 minutes after the appliance is acti-
vated.
If a closed circuit is detected by the drain temperature sensor, the error is displayed immediately.

Solution
Replace the sensor if it is faulty.
Replace the sensor if it is faulty.
Correct the installation position to prevent the air
intake and output from clogging.
Remove the obstruction and resume operation.
If the voltage is normal, replace the PUMP. If
the voltage is abnormal, replace the PCB MAIN
board.
Remove the obstruction and resume operation.
If the same error code appears again, replace
the HIGH PRESSURE SWITCH.
If the same error code appears again, replace
the HIGH TEMPERATURE THERMOSTAT.
Replace the sensor if it is faulty
Recover the refrigerant and then reload the
required mass.
In case of an abnormal value, replace the coil.
Correct the installation position to prevent the air
intake and output from clogging.
Replace the sensor if it is faulty.
Recover the refrigerant and then reload the
required mass.
Remove the obstruction and resume operation.
