Hi,

went to a breakdown today, boiler has 240v and a flashing orange B every 2s, Hot water demand nothing no power to pump or fan, no ignition and the same with a heating call from the mechanical clock, suspected the clock may be faulty so I bridged the switch wire but still nothing, so flashing B orange light every 2s, looking at some sort of board fault, anyone have any thoughts
