Cause
It is not possible to lower the
pressure when flushing takes
place.
During the flushing process,
no pressure could be ascer-
tained at the low pressure
connection of the air condi-
tioning service unit.
During the software test, the
compressor failed to reduce
the internal pressure suffi-
ciently.
It was not possible to drain
any used oil during the soft-
ware test.
It was not possible to remove
any refrigerant from the inter-
nal tank during the software
test.
No USB stick was found/rec-
ognised
Troubleshooting
Remedy
Check air conditioner and
connections for leaks, con-
strictions and ice build-up.
Check pressure transducer
calibration.
Connect low pressure hose
to the flush container and
open valve.
Residual pressure on the
pressure gauges?
Check pressure transducer
calibration.
Check internal bottle pres-
sure.
Check the compressor and
the corresponding solenoid
valves.
Is there residual oil in the dis-
tillator, or was the draining of
used oil interrupted during
the last process?
Insert bottle for used oil cor-
rectly.
Is there a vent hole in the
used oil container/is the vent
hole clogged?
Check pressure transducer
calibration.
Check whether the tank
valve on the internal tank is
open.
Check the RE valve.
Is the ambient temperature
below 10 °C?
Insert the USB stick.
Make sure that the USB stick
has been formatted with the
FAT32 file system.
