Fault
Possible cause
Cure
A01
No burner ignition
No gas
Check the regular gas flow to the boiler and
that the air has been eliminated from the pipes
Ignition/detection electrode fault
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits;
replace the electrode if necessary.
Faulty gas valve
Check the gas valve and replace it if neces-
sary
Insufficient gas supply pressure
Check the gas supply pressure
Trap blocked
Check the trap and clean it if necessary
Air/fume ducts obstructed
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals.
