Yes new 1234
Not 5 yet

Faulty pcb with dodgy relay ...? Possibly

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

 

[SimonG]

Needs diagnosing properly by a gas safe engineer.

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 ...
