Boiler Hot, Pilot On, Radiators Cold. Mystery Programmer... can anyone help

[JustWannaBWarm]

I can't find anything else around the boiler or other parts shown in the pictures, the only other parts I can see are another bigger, black water tank next to the one shown, and the room thermostat dial

 

[JustWannaBWarm]

Did you find the overheat stat ?

Do you think it's worth turning the boiler itself completely off and letting it cool down before messing with everything again? Not sure what order to do things in

Grey button on gas valve doesn't look like it's all the way out????

If the pilot is still lite it wont be the overheat stat (I did not realise the o/heat stat was part of the thermocouple) is there any water in the black tank ?

Good spot

The op said the heating was running so would he have fecked about with the gas valve ?

The tank (shown) seems to be about two thirds full

My 'mate' has gone off to Australia, it is now unclear exactly what was 'fecked with', so to speak, but I was under the impression just the programmer

You've been in the game long enough to know not to listen to what the custard says...

I'm starting to think they may have relit the pilot after overheat stat cut it off and have not turned the pilot knob fully to on position.

Gas valve grey button should automatically spring to fully open , some tend to stick holding off main gas.
Would be surprised to find an OH stat on this one..

The pilot has not gone out through whole process, I have pulled that grey knob fully up, programmer on, which resulted in a firing up noise. will check radiators again in ten minutes. Thanks for the thoughts so far everyone

If the black water tank leaks or overflows , all your electrics get wet! Not very clever

I think you owe @Gaswizard a beer!

I probably owe you all a beer, radiators and pipes still stone cold though, but maybe will take a bit longer than they did before since they haven't been warm for a few days
