Ravenheat CSI 85 Boilern fault?

The only way I can get my central heating to work is if I switch the boiler of at the mains leave for an hour and switch on. It will then run for 5 minutes and cut off, leaving me with no heating or hot water

I would start by replacing Primary (CH) thermistor, it's on the right hand side of boiler and should be green. The boiler will require draining. These cost about £20.
