    Looking for some guidance please.
    I have above boiler, its the 35 store, been in 6 years and now it trips out (at boiler reset on boiler) when calling for hot water, after about 4 or 5 miinutes run time. central heating no poblems, had heat exchanger replaced about 2 years ago and high temp thermistor or dhw side.
    Any Ideas? have been told it could be plate heat exchanger but heating side ok, do have a combimate on supply pipework.
    any advice greatly appreciated.
