Mend Alpha CB28 Central Heating Combi Boiler Spares

central heating ok but no hot water most of the time?

I have an alpha CB28 combi boiler, central heating working fine. Hot water only heats for about a minute after pressing reset button apart from that it is cold. What could be wrong, how could i fix it and where could i buy spares.
