Demand boiler behaving oddly....

Modern boilers have lots of safety checks built in. Maybe one of them was triggered? e.g. flue seemed blocked due to string wind or high level thermocouple tripped.

You haven't had a power cut (electricity) you didn't notice did you?

Interesting - do these things generally 'uncheck' after the problem has gone away?

Only change in the norm I could point to is that it's rained without stopping for almost 48 hours here.

No, definitely not. Good thought though :-) --

Normally yes, sometimes there is a manual reset button. This would be documented in the boiler manual, have you got one? Installers should leave the installation and the user instructions.

Maybe a little of the rain got into the boiler ...

OK, expert called out, transformer had burnt out, now all hunky-dory. Thanks for all the input....
