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; replace the electrode if
necessary.
Check the gas valve and replace it if
necessary
Check the gas supply pressure
Check the trap and clean it if necessary
Remove the obstruction from the flue,
fume extraction ducts, air inlet and ter-
minals.
Check the ionization electrode wiring
Check the condition of the electrode
Electrode to ground
Cable to ground
Check the trap and clean it if necessary
Check the card
Check the 5-pin connector wiring
Check the fan
Check the position of the ionization
electrode and replace it if necessary
Check the burner
Remove the obstruction from the flue,
fume extraction ducts, air inlet and ter-
minals
Check the trap and clean it if necessary
Check the exchanger
Check the flue gas probe
Check the flue material parameter
Check the correct positioning and oper-
ation of the heating sensor and replace
it if necessary
Check the circulating pump
Vent the system
Check the correct positioning and oper-
ation of the return sensor and replace it
if necessary
Check the circulating pump
Vent the system
