f1-f4 this will proberly mean you need a new burner door seal kit/although it means ignition fault, the seals on the burner are inadaquate and the manefacturer has brought out a modification, bluntly the seal around the burner is not air tight when your boiler is on condesation is filling up inside were some of the electrices are in causing the fault ..
get it fixed as soon as you can for left alone could cause a lot on damge and cost a packet to fix.
