3.4 Troubleshooting

Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In the case of a boiler fault, the display will light up,
indicating the fault code and, in case of connection in cascade, the number of the module.
There are faults that cause permanent shutdown (marked by the symbol OK to reset): to restore operation, just press
the OK button for 1 second or RESET on the remote timer control (optional) if installed; if the boiler fails to start, the
fault must be eliminated first.
Other faults cause temporary shutdowns which 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 ionization 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 ionization 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, 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
