It is 10 years old there is a lack of hot water, i can only get hot water from it if i have the central heating on, otherwise have to run taps very slow for warm water. Have changed both the DHW temp sensor and CH temp sensor to no avail HELP!!
To Ainsleys plumbing and heating, thank you very much for your suggestion, have changed DHW diaphragm, now boiler works like new saved me a fortune.

It could be the D.H.W. diaphram needs changing if the boiler does'nt fire when you run the hot tap. If it does fire up feel the heating pipes coming away from the boiler, if the flow starts heating up the diverter valve needs changing as the heat is going round the heating circuit instead of the D.H.W
