Worcester Bosch 240 RSF - no heating or hot water

Worcester Bosch 240 RSF combi boiler


Today my boiler stopped working: the pilot light is on (permanently), but when there is demand for either heating or hot water (or both), the main burner does not fire up.

Can't work out why - what tests can i do to find out what is wrong?

I don't know how to tell, for example, whether or not the pump is running, or whether the fan is running - how do I know? There is a soft sound coming from the boiler, but it seems to be there regardless of whether there is demand.

Thanks for any advice!
