Calibration failed Internal scale is not calibrated.
Select
to repeat the calibration check (with
optional kit). If the calibration procedure continues
to fail, exit the current test and contact an authorized
Bosch service center for repairs.
Stalled charge The refrigerant is stalled inside the tank or
in the machine.
Make sure that the connections are firm and the
valves are in the correct position.
Database not available The machine was shipped without database
installed.
Contact an authorized Bosch service center for more
information.
Tank excessive weight Safety circuit tripped for tank too full. The
machine is locked because there is too
much refrigerant in the internal tank.
Contact an authorized Bosch service center for more
information.
Exhausted filter. The Filter
must be replaced
FILTER WEIGHT XXX.xyy
Replace the filter now?
The last time the filter was replaced
150 kg (331 lb) or more refrigerant was
recovered.
Refer to the Filter Maintenance section of this manual
for instructions on how to replace the filter.
The serial number has already
been used. Re-enter or exit?
The filter serial number entered in the
machine is incorrect.
The filter has already been used on this machine. Get
a new original Bosch filter no. SP01100355
High pressure switch activated
The machine is locked because the pressure
inside the tank is too high, maybe because
of the excessively high temperature of the
tank.
Allow the machine to cool before attempting further
operations on the A/C system of the vehicle. If the
problem persists, contact an authorized Bosch
service center for more information.
Inlet pressure too high for
vacuum
Before the station proceeds with the
evacuation of the A/C system, check that
the system pressure cannot damage the
vacuum pump. In this case, the system
pressure is greater than 0.35 relative bar.
Select
. Refer to the Recovery section of this
manual to recover the refrigerant before proceeding.
Insufficient refrigerant.
6,0 kg (13,2 lb) required for
system flushing
There is not enough refrigerant in the
internal tank to flush the system.
See Tank filling in the Maintenance section of this
manual.
Insufficient refrigerant
available for charging
The charging function does not start if the
value set for the charge is higher than the
refrigerant contained in the internal tank.
See Tank filling in the Maintenance section of this
manual.
Invalid code entered! The activation code entered in the machine
is incorrect.
Check that the activation code was entered exactly as
it was received. Use uppercase if necessary.
Invalid serial number.
Re-enter or exit?
The filter serial number entered in the
machine is incorrect.
Check that the serial number entered corresponds
to the serial number in the filter. Check that the filter
has not been used previously on another machine.
Unsuccessful sealing test There is a leak in the A/C system. Exit the current test and repair the A/C system of the
vehicle.
No pressure on the inputs,
check the connections
Recover anyway?
System pressure below 0.35 relative bars. Check that the hoses on the high pressure (red) and
low pressure (blue) sides are connected and that the
valves of the connections are open. Select
to
recover; Select
to bypass the recovery and
proceed with the Vacuum.
Locked oil drain The accumulator pressure did not rise above
1,10 bar within the minute before the oil
discharge that had to be carried out.
Proper pressure inside the accumulator is required
to force the oil, previously separated from the
refrigerant, outside the system. Select
to retry;
select
to exit.
Oil residual time xx:xxx
Change oil now?
The remaining vacuum pump oil residual
time appears before the machine is locked.
Refer to the Vacuum Pump Oil Change of this manual
for instructions on how to replace the vacuum pump
oil.
Out of range
Accumulator pressure sensor
The accumulator pressure transducer does
not correctly read the pressure.
Exit the current check and contact an authorized
Bosch service center for more information.
Out of range
Air flow sensor
The air flow sensor does not correctly read
the air flow.
Exit the current check and contact an authorized
Bosch service center for more information.
