Problem with Ravenheat RSF 820/20 combi boiler?

I have just drained the hot & cold water from the system, when re-filled the central heating works fine, but the dhw does not get hot. When I turn the hot tap on, the boiler fires up, water comes thru the tap, but doesn't get hot. But the rads. seem to get warm. Problem only started after I drained the system. Can anyone help please.
