by toping up the presure you are only adding water (not gas) to your central heating system. be carfull not to put any more than 3 bar presure in, 1.5 bar is enough for two story house

look at your thermisters (litle prob with 2 wires) or your heat exchanger

The compact he frstly has 3 safety interlocks to satisfy 1.the water pressure switch must be made 2.the condensate pressure switch should not be made and lastly the air pressure switch then and only then does the ignition control board take over. It could just be a simple problem like venturi to the air pressure switch blocked or it could be the ignition board.

get someone in to look at it , it might need the venturi cleaning if the fan is running but not bringing on the gas.
