Model No, would help, IF it is a combi boiler, It will not have a pilot light, It will light when needed. Check the pressure if a combi, should be about 1 bar, if not, you will find a flexible pipe some where close to the boiler, whith a valve on it. That is the fill loop, use that to increase pressure. If that fixes it, monitor pressure, as you might have a leak.
PS sob stories not needed, We help if we can, and if we see the question.
