Sorry, at least no need to imagine now!
Is it a gas fired boiler? Do you have 1 bar of pressure?
Yes. and yes.
I've also checked the regulator and the ignition spark, everything seems to be in order.
I suspect the thermocouple.
I had a horrible day yesterday. Everything I touched went wrong, and I came down with man-flu and cut my thumb into the bargain. Then, to top it off, I entered an online MTT where you get 3k starting chips, but 5k for the add on, and we had a power cut which lasted for precisely long enough to cover the add on period.
Bugger.
I don't usually document bad days in much detail because people think I'm complaining about how unfairly life is treating me, when in reality, nothing could be further from the truth. When I write about things going wrong, I'm not feeling sorry for myself, not in the slightest. I'm just documenting it, as I would any other event.
If you can meet with triumph and disaster
and treat those two imposters just the same...
