Evening all,
I have recently been having some trouble with my Baxi Solo 2 50 PF boiler. I have cover for it through Scottish Power and eventually after numerous visits by their engineers and a new fan, PCB, pressure switch and gas valve the problem was solved.
The boiler is now working well except for one odd issue. Approximately 5 mins after the boiler switches off (i.e. after the timer has switched it off) it suddenly makes quite a loud chuffing noise. It just doesn't chuff continuously, it only does it the once - 'chuff'. To me it sounds like a sudden release of pressure, maybe air. I cannot smell any gas so I am assuming it is not that.
The noise is similar to when the main gas burner ignites, but is quite a bit louder (we can hear it from upstairs). I wondered if it might be that the new gas valve was faulty and wasn't closing properly allowing the flame to continue burning until eventually it extinguishes with a pop, however I cannot see any flames through the little window when the burner has switched off.
Could it be that as the boiler cools down there is a faulty gasket or something that is allowing air to pass somewhere (releasing a vacuum or something)?
Any ideas would be appreciated. I could phone Scottish Power yet again however I think this issue would be difficult to diagnose because it would be difficult to replicate when the engineer is here.
Best regards,
Rob
