A lack of flow, a lack of temperature or both? As Grumpy says the likely probles are the diverter valve or the secondary heat exchanger. The problem can usually be diagnosed by looking at the indicator lamps and seeing what the boiler does.
If you turn on the hot tap does the hot water demand lamp come on? Does the boiler then fire up?
Do you get hot water if the heating is already running?
Rads. get hot. Tap water pressure good. Water comes out warmish then cools after about 20 seconds.
