Hi, ive been having a problem with my boiler, when i moved in it was working fine everything fired up, then one day the gas board decided to dig up the street and turn our gas off, gas was turned back on but within a couple of weeks the boiler stopped working, as soon as you switch it on it sounds as though everything is fine but when it comes to fire up it clicks a few times and then the ignition fault light comes in. hopefully someone can help, many thanks in advance.
