are you sure the filling loop is closed properly 
your over pressure is a problem but it isn't causing the ignition problem. that's more than likely your air pressure switch. which eurocombi sx20 or a23?
Thanks,i have managed to solve the ignition fault but the pressure remains high (4 bar) ! could reduce this by draining some water out of the system and having the filling loop closed at the same time ???
