Pump working? Sounds like a circulation issue.

 

[SimonG]

So it's had 1,2,3 and 4?

 

[Dave e]

Pump working
Yes new 1234
Not 5 yet

 

[Dave e]

Faulty pcb with dodgy relay ...? Possibly

 

[Riley]

I’d say unlikely. Are you gas safe?? Who carried out these repairs

 

[SimonG]

Needs diagnosing properly by a gas safe engineer.

Out of interest how much £ have you spent so far to achieve
No solution ? It will lead us all on here to give advice in the future please keep,us updated kind regards...I suppose I am asking because at some financial point it’s best to write the thing off and without your valued input we cannot assist others with advice
On this basis we can advise about suitable replacements in the future based in repair costs v new boiler installs

Before your boiler shuts off, does it sound similar to kettle boiling followed by a little banging and clanking?

 

[Dave e]

Yes spent nearly £400. No banging or clanking.
Might have to admit defeat and get a new boiler oh well it served me well was a good boiler ...
