Table of faults
Table 8- List of faults
Fault code 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 necessary
Insufficient gas supply pres-
sure
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.
