my britony combi boiler has blown the internal fuses?

firstly the cause of the fault has to be found. what i would do in this case is disconnect all the connections from the pcb board. then replace the fuse. turn back on the power and see if the fuse blows. turn back off the power and plug in each componant individually until you determin which one is blowing the fuse. ie is it the pump, the fan, air pressure switch, then replace the faulty part. hope this helps.
