4.4 Troubleshooting
Diagnostics
In case of operation faults or problems, the display flashes and the fault identification
code appears.
There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the reset button (detail 6 -fig. 1) for 1 second or RESET on the op-
tional remote timer control if installed; if the boiler fails to start, it is necessary to firstly
eliminate the fault.
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
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
Check the burner
Check the Offset adjustment at
minimum power
Remove the obstruction from the flue,
fume extraction ducts and air inlet
and terminals
Check the trap and clean it if
necessary
Check the exchanger
Check the wiring or replace the sensor
