I Have an Alpha CB28 Combi Boiler which is doing a very strabge thing. If I turn on the central heating system it works a dream, however if I only want to get hot water out of the taps no go! What could it be and can I fix it myself?

If memory serves, you're lucky. Alpha is one of the few makers that actually sells a replacement div valve diaphragm as an official spare part.
It's more likely to be the horse shoe switch that clips on to the divertor valve.When you remove the switch from the divertor the boiler should fire up.Open and close the switch with your finger to ensure that the boiler fire every time the switch is released.If it dosent then its the switch if it does then its the diaghram.
