INSTRUCTIONS FOR THE USER
Electronic self-diagnosis
The circuit board performs 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 relevant 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.
