I have a glow worm swift flow combi boiler. When the central heating switch is turned off i do not always get hot water until I turn the central heating switch back on. It also makes a clicking noise sometimes when it is firing up. Any suggestions as to why the water is not always hot?

DHW flow switch located l/h side may not be working, run tap and check for continuity across flow switch leads, shorting out flow switch should also start hw demand (but ensure tap is running to stop over heating) check fault finding in instruction manual. ps on hw demand pump stops.
