In the manual you should find a tree diagram or flow chart. Look at it to see the sequence that things should occur in.
Usually - after checking water pressure &... - the fan starts. IF the fan is too slow (as detected by an air flow sensor) then it cuts out. Hence fault A. Is the fan spinning?
If it "clicks" but no flame - or flame but for only a few seconds - B or C
I think D is not likely - as usually means temp control is out for hot water or heating - I think there are separate thermistors....
Good luck - I suggest you phone Potterton & get them to reccomend an engineer to fix it - if you don't get far...
