Nope do u hav an engineer? I think ur doin it urself? This component controls gas pressure leave it alone
Wouldn't think of doing it myself - I'm just thinking my engineer should have known this when he replaced the PCB. When I spoke to him earlier he didn't think it was anything to do with the PCB although that is the only component that has been changed. He was suggesting a system flush would cure the problem. The water was scalding hot before the lockout so it seems logical that it maybe something to do with the PCB especially since you've mentioned the jumper settings. Just want to point the engineer in the right direction and get him to check the jumpers, that's all. Just been informed by the missus, the radiators are also not hot !
I often invite the end user to watch, but if he of she told me what to do, I would be out of there

Engineer is adamant that the water not being hot is nothing to do with the PCB having been replaced, he is saying it has to be something else. I am in a bit of dilemma seeing as I have already spent over £200 replacing the PCB and the issue is not fixed, what's to say replacing another part will fix the issue ? Do I call in another engineer, explain what has been done so far and let them diagnose the problem ? If I were to post a photo of the PCB would anybody on here be able to tell just by looking if the jumpers have been set correctly ? I realise I will have to identify the type of gas valve.

The hand written date makes me think that that it is a repaired PCB and not new. That means that it will not come with any documentation.
Since most of that model of boiler use the other SIT gas valve, it would not be at all surprising if the engineer was not aware of the need to change the setting on the PCB.
So it needs to be gently pointed out to him what is required and ideally to point him towards this thread.
In the boiler world there are many little aspects of repairs which not every engineer is going to know. Not helped when they use repaired parts which don't come with the manufacturer's documentation.

Depending on the engineer, unless he specialises in Vaillants then he is likely to need to look it up.
If I am right that its a repaired PCB as evidenced by the writing on it, then did you know that it was a repaired one?

Do u know the jumper setting tony?
I often put dates etc on a pcb for future reference. Tony why do you look down your nose at other folk who carry out work. You hardly ever have anything pleasant to say about a fellow engineer
