Had a faulty moterised valve which I replaced, but now boiler won't fire up. Valve seems to be working properly. Could this be a related problem? Any suggestions

Did you replace the complete valve, just the synchron motor or the valve head? Have you wired back in the auxillary switch? What manufacturer is the valve?
