3.4 Troubleshooting
Fault Diagnosis
The boiler is equipped with an advanced self-diagnosis system. In the event of trouble with the boiler, the 3 LEDs
will indicate the code of the fault.
There are faults that cause shutdown: in order to restore operation it suffices to turn the selector (ref. 3 - fig. 1)
onto RESET for 1 second and then back onto
remote timer control if this is installed; if the boiler fails to start, it is necessary to resolve the fault indicated by the
operating LEDs.
Other faults cause temporary shutdowns that are automatically reset as soon as the value comes back within the
boiler's normal working range.

positioning and operation
of the heating sensor
• Check the circulator
• Vent the system
• Check the ionizing electrode
wiring
• Check the card
• Check the wiring
• Check the fan
• Check the pressure switch
• Change the diaphragm
• Fill the system
• Check the sensor
• Check the wiring or change
the sensor
• Check the wiring or change
the sensor
