Dear Agile!
I don't remember you telling me anything of the sort!
I've checked back on the posts and nowhere do you mention taking out the little plastic plug to get to a reset switch!
!
(Stuck that in for good measure, seeing as we seem to be shouting.)
You mentioned test modes and carbon monoxide!
If you could paste in a reply the exact portion of what you told me ages ago for free relating to the little plug, I'd be most obliged.
!
(Missed that off on the previous line)!
As I said before, the control knob reads RESET!
To me, that means turn the knob to RESET!
Not being a boiler engineer, I didn't know there was another place to reset as well!
And you didn't tell me!
Am I a mind reader!
Why would you be pleased, therefore, that it cost me £130?!
How have I upset you!
If you can prove I've not listened to your free advice, I'll apologise!
If you can't, I'd hope you'd do the same!
