Yeah I'm leaving that stuff well alone. I'm getting a guy around next month to look at it, it would be nice to know before then what the problem is.
Either way I'll post my experiance once it's fixed for other people's reference.
Thanks.
Hi there, sorry to bump an old thread but my boiler (same make and model) is experiencing exactly the same problems as those described here.
May I enquire as to what the eventual problem and solution was?
Thank you
