Cause
Internal scale is not calibrated.
The refrigerant is stalled inside the tank or
in the machine.
The machine was shipped without database
installed.
Safety circuit tripped for tank too full. The
machine is locked because there is too
much refrigerant in the internal tank.
The last time the filter was replaced
68 kg (150 lb) or more refrigerant was
recovered.
The filter serial number entered in the
machine is incorrect.
inside the tank is too high, maybe because
of the excessively high temperature of the
tank.
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.
There is not enough refrigerant in the
internal tank to flush the system.
The charging function does not start if the
value set for the charge is higher than the
refrigerant contained in the internal tank.
The activation code entered in the machine
is incorrect.
The filter serial number entered in the
machine is incorrect.
There is a leak in the A/C system.
System pressure below 0.35 relative bars.
The accumulator pressure did not rise above
1,10 bar within the minute before the oil
discharge that had to be carried out.
The remaining vacuum pump oil residual
time appears before the machine is locked.
The accumulator pressure transducer does
not correctly read the pressure.
The air flow sensor does not correctly read
the air flow.
Solution
Select to repeat the calibration check. If the
calibration procedure continues to fail, exit the
current test and contact an authorized Bosch
service center for repairs.
Make sure that the connections are firm and the
valves are in the correct position.

Refer to the Filter Maintenance section of this manual
for instructions on how to replace the filter.
The filter has already been used on this machine. Get
a new original Bosch filter no. SP01100355
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.
Select . Refer to the Recovery section of this
manual to recover the refrigerant before proceeding.
See Tank filling in the Maintenance section of this
manual.
See Tank filling in the Maintenance section of this
manual.
Check that the activation code was entered exactly as
it was received. Use uppercase if necessary.
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.
Exit the current test and repair the A/C system of the
vehicle.
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
recover; Select to bypass the recovery and
proceed with the Vacuum.
Proper pressure inside the accumulator is required
to force the oil, previously separated from the
refrigerant, outside the system. Select
select to exit.
Refer to the Vacuum Pump Oil Change of this manual
for instructions on how to replace the vacuum pump
oil.
Exit the current check and contact an authorized
Bosch service center for more information.
