I've been having a bit of trouble over past few weeks with greenstar 24i condensing pipe freezing up at a weak corner point which has not been insulated properly. As suggested a kettle of boiling water usually does the trick but this time after checking, it would appear that there is no frozen water in the condensing pipe at all. The usual gurgling still sounds in boiler and the green flame light does not want to go on as if there is a freeze somewhere. The red light flashes twice to each blue flash and I have mislaid my manual so I'm not sure what the flashing sequence means.
I'm sure it will be something simple but so far I can't work it out.
It's ok folks,
A lot of perserverance and I found the freeze that i didn't think was there. It's been really cold up here - minus degrees for a few weeks now but last night was the worst.
All the best

if you're getting the gurgling noise then it's the condensate pipe that's blocked, or the condensate trap may be blocked, but that's a job for an engineer to take care of.
