I am not sure whether or not I just got a "weak" CO2 cylinder last time or whether there is some more serious problem. It seems to bubble normally, but the water is just not carbonated.
I'll remove and remount the cylinder, but will probably just replace it and hope the new one works better. If not, I guess I'll just chuck the machine. Too bad, I have had a lot of use out of it and been happy, in up to now. I make about two liter bottles a day on average.
The machine is about a year old.
I seem to need more words in order to submit the story. I will do so.
