can you tell me if my boiler is broken it is a worcester 241-rsfl/l combi b?

i have a static caravan and yesterday the heating was on and at about 9.30 last night it went of and when we tried to put it back on it wouldnt go the pump started but it was like the boiler wouldnt ignite. do you think it could be the boiler has broke or do you think its an easier problem to sort out
