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 shutdowns (marked with the letter "A"): to restore
operation it is sufficient to press the RESET button (part 8 - fig. 1) for 1 second or use
the RESET on the remote timer control (optional) if installed;if the boiler does not restart
it is necessary to resolve the fault first.
Other faults cause temporary shutdowns (marked with the letter "F") that are automati-
cally reset as soon as the value in question returns to 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 and replace it if necessary
Check the ionisation electrode wiring
Check the card
Check the correct positioning and
operation of the heating sensor
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
Check the wiring or replace the sensor
Check the wiring or replace the sensor
Check the wiring or replace the sensor
Check the wiring or replace the sensor
Check the 3-pin connector wiring
Check the 5-pin connector wiring
Check the fan
Check the electrical system
Check the electrical system
Check the system water pressure
Reconnect the external probe or disable
the sliding temperature
