4.4 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 22 - fig. 1) indicating the fault
code (detail 21 - fig. 1).
There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the RESET button (detail 8 - fig. 1) for 1 second or RESET on the
optional remote timer control if installed; if the boiler fails to start, it is necessary to first
eliminate the fault.
Other faults (marked with the letter "F") cause temporary shutdowns that are automati-
cally 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
Check the gas supply pressure
Check the trap and clean it if necessary
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
See fault F07
See fault F15
Check the position of the ionisation electrode
and replace it if necessary
