The engineer who attended was helpful and repaired my boiler. However, I've not been able to get to the bottom of the problem. There doesn't appear to be access to some sort of technical helpdesk who could offer an explanation. I was advised that your boiler wasn't faulty and that's as much as you could offer. I'm sure you can check the details in the fault notes
