Hi guys, been called to this boiler, no heating or hot water, fan runs, could smell gas (escaping out flue gas test point, worryingly the o ring had came off the bung so not sure how long it's been like that ) so if I'm smelling gas the gas valves operating but getting no spark. I haven't looked yet but water could be dripping onto one of the connections as you'll see in the pic. From the pic, is it worth trying to repair or should I scrap it?
