Cause
Internal scale is not calibrated.
The refrigerant is stalled inside the tank or
in the machine.
The machine was shipped without data-
base 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 re-
covered.
The filter serial number entered in the ma-
chine is incorrect.
The machine is locked because the pres-
sure inside the tank is too high, maybe be-
cause of the excessively high temperature
of the tank.
Before the station proceeds with the evacu-
ation of the A/C system, check that the sys-
tem 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 inter-
nal 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 ma-
chine 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 cal-
ibration procedure continues to fail, exit the current
test and contact an authorized Bosch service cen-
ter for repairs.
Make sure that the connections are firm and the
valves are in the correct position.
Contact an authorized Bosch service center for
more information.

Refer to the Filter Maintenance section of this manu-
al 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 fur-
ther 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 fil-
ter has not been used previously on another ma-
chine.
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
to 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 refrig-
erant, outside the system. Select
to exit.
Refer to the Vacuum Pump Oil Change of this man-
ual for instructions on how to replace the vacuum
pump oil.
Exit the current check and contact an authorized
Bosch service center for more information.
