7. Troubleshooting
Refer to Table 7.4 for solutions to the most common malfunction situ-
ations.
If the proposed solutions do not work, enter self-diagnosis (para-
graph 7.1) to determine if there are failed components.
WARNING - DO NOT SERVICE THE MACHINE YOURSELF
Call the service center in any of the following cases:
• the machine has a problem that is not listed in table 7.4
• none of the remedies proposed by the table work
• control board self-diagnosis shows one or more failures.
7.1 Control board self-diagnosis
The control board is equipped with a self-diagnosis software that can
detect common problems to the pneumatic circuit.
1. To enter self-diagnosis mode, press and together for two
seconds. The letter “C” appears on the PROG display.
2. Press button once. The letter F appears on the PROG dis-
play. The other displays (STEAM, MIX/ PAUSE, AIR) show infor-
mation concerning the status of the pneumatic circuit:
• If there is no failure, the displays show: F -- -- --
• If there are failures, the display STEAM shows the number
of failures occurred (use + or – to scroll all the referenc-
es). The display MIX/PAUSE shows the code of the failed
component. The display AIR shows the code of the type of
failure.
Failure references are displayed using the codes in tables 7.1 and
7.2.
Figure 7.3 shows an example:
The pneumatic circuit has more than one failures.
The displays show information regarding failure number 2: the back
clamp solenoid valve has no power.
To erase faults memory, press PROG until the displays
show: F -- -- --
To exit self-diagnosis program, press and together until the
displays STEAM, MIX, PAUSE, AIR show pressing times.
