Hi all, I did a LGSC today, on a 1-year-old Worcester combi.
Pics attached of the flow and return pipes to the boiler, coated with green powdery but dry residue. And also the pipe tray/cover, which had a sticky green residue. No other issues anywhere. But because it's just the central heating pipes affected, I'm a bit puzzled. Any ideas anyone?
