how to fix Vaillant boiler?

I have a vaillant T3W Combi boliler. I emptyied the system of water to fit a new rad and after re-pressurising the system the boiler motor comes on but no hot water is produced, there is no 'tap' hot water either. The flame does not ignite inside the boiler as if hot water is being produced.
