This boiler is in fact a worcester boiler badged up as a BG boiler, have had numerous problems myself with the EA fault and can be down to several issues. Combustion ratio, ignition electrodes, gas valve, condensate backing up, heat exchanger, circuit board and wiring harness. cant understand if it takes several attempts for it to light why this hasnt been diagnosed by the BG engineers?? What have they done so far?
