Greenstar 24Ri boiler won't light and the blue light is fast flashing. From the manual I can see that the issue is a volatile lockout. Most likely a sensor issue.

I will get someone to look at it, but my question is reset isn't working. When I had an issue before I could reset the boiler and it would work for a while (better than being cold) whilst I waited for a proper fix. Any tips on muddling along until it can be fixed?

Possibly the fan has failed. Get a Gas Safe engineer to look at it.
Think about getting a service contract in place,
