Hello. First post here. Any assistance gratefully received!
I have a Vaillant Combi boiler, around 7 years old (I cannot determine the model number.)
The pilot light goes out every time that the boiler is not being called upon. This has been happening for around 2 weeks now.
eg
we have the central heating on timer, when we are out or in bed (ie heating off and no hot water being used) the pilot light always goes out (every time.)
we turned the heating onto constant (low) and the pilot light stays lit.
we returned to timed heating, and the pilot light goes out again.
we are sure that it is not a draught, because it extinguishes every single time the heating is out, regardless of the weather.
the boiler is shown below (please excuse the stuff around it, it is in a cupboard!)
I am guessing it could be a thermocouple, but surely this would fail even when the heating was on? I have determined this morning that we have some air in the towel rail in our bathroom - could this be causing the problem?
Thanks for any assistance
Leon
