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 20 - 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 8 - 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 first eliminate the fault.
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 and replace the gas valve

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 efficiency of the flue, fume extraction ducts
and outlet terminal
Check the correct positioning and operation of the
fume sensor
Check the wiring or replace the sensor
