I am getting error code E110 the fan starts for about 30 seconds then stops, before this code i was getting E160 and a plumber replaced the PCB he is now telling me that the fan has gone, could this be true?

if the fans working why does it need replacing ?.
anyway i dont think your plumber all there most likely it will be the air pressure switch. get another plumber in or when he is there call heat team the boiler manufacturers they can help u diagnose over the phone with out u wasting more money
