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 20 - fig. 1) indicating the fault
code.
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 firstly
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, except
for fault F37 which is reset by turning the unit off and then on again with button 14 of
fig. 1.

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 nec-
essary
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 opera-
tion of the heating sensor
Check the circulating pump
Vent the system
