Intermittent fault, Eurocal with Sterling ST108

[Dotty]

As it happens I had one on Friday with an intermittent fault, the young lad before me thought pump but when I checked I decided that there was no positive difference between open and closed on the KBB.

Replaced.

I'll take this opportunity to thank everyone for their replies and input towards this post! I do wonder why there isn't a private forum for oilies like the gas safe one though? Anyway thanks again chaps! :rockon2:

How would that create a fault - was it just very poor flow when open? Cheers

Geminox Astrane.Bentone ST 108 burner.Intermittently fires up and then starts 'chattering' for a couple of seconds and then locks out.Noticed that a lot of air bubbles collecting in fuel filter when pump is running.Photocell changed,control box changed,pump changed some time ago.This problem has defeated French plumber who installed it,so he won't attend anymore.(I'm in Brittany)Excellent boiler but this problem is doing my head in.Any good folk come across this before?

Lot of bits changed, whats the pressure gauge read?

dont take this as criticism, but when servicing a boiler and you see something needs doing, why dont you repair/replace the part, because if you dont how can you say you have serviced the boiler, knowing its got issues that invariably lead you to having to go back to sort it out?

If you mean air bubbles in tiger loop , one of two things small leak on line or flexible oil hoses has a pin hole. Had one like this before .
