3.4 Troubleshooting

Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 11 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore
operation, press the RESET button (detail 6 - fig. 1) for 1 second or use the RESET on
the optional remote timer control if installed; if the boiler fails to start, it is necessary to
eliminate the fault indicated by the operation LEDs.
Other faults marked with the letter "F" cause temporary shutdowns that are automatically
reset as soon as the value returns within the boiler's normal working range.

Cure
Check the regular gas flow to the boiler and
that the air has been eliminated from the pipes
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits
Check the gas valve and replace it if
necessary
Adjust the ignition power
Check the ionisation electrode wiring
Check the card
Check the correct positioning and operation
of the heating sensor
Check the circulating pump
Vent the system
Check the thermostat
