The circuit boards perform continuous self-
diagnosis. In the event of hardware faults or
malfunctions in the circuit board that could
be dangerous for the end user, the device will
assume “safe” mode, the solenoid valves are
deactivated and the display shows the relative
fault code.
Generally, the default operating parameters
are restored by disconnecting and recon-
necting the power supply. This action will re-
solve most problems.
If the fault persists, contact your nearest ser-
vice centre.
Fault types and codes are shown in the follo-
wing table.
