Cure
Check for correct gas flow & pressure to the
boiler and that the pipework has been purged.
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits;
replace / clean the electrode if necessary.
Check the gas valve and replace it if necessary
Check the gas supply pressure
Check the trap and pipes, clean it if necessary
Remove the obstruction from the flue, extraction
ducts, air inlet and terminals.
Check the ionisation electrode wiring
Check the condition of the electrode
Electrode to earth
Cable to earth
Check the condenser trap clean it if necessary
Check the PCB
Check the 5-pin connector wiring
Check the fan, clean or replace
Check the position of the ionisation electrode and
replace it if necessary
Check the burner
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals
Check the trap and pipes clean it if necessary
Check the exchanger
Check the flue gas probe
Check the correct positioning and operation of
the heating sensor and replace it if necessary
Check the circulating pump
Vent the system
Check the correct positioning and operation of
the return sensor and replace it if necessary
Check the circulating pump
Vent the system
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 flue probe
