INSTRUCTIONS FOR THE USER
Electronic self-diagnosis
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 reconnecting the
power supply. This action will resolve most problems.
If the fault persists, contact your nearest service centre.
Fault types and codes are shown in the following table.
