low hot water pressure and no hot water?

I have a worcester bosch 230 combi. I recently changed the pressure relief valve and expansion vessel. All was well until this morning. I turned the hot tap on and the pressure coming out is abnormaly low and it does not fire the boiler up on demand. Any ideas please.
