Thanks for the writeup! Great description and resolution information. This condition is known as “Air Locked” (or CO2 locked technically) – where there is too much CO2 (or more accurately – CO2 pressure) in the Cabonator tank, and therefore it will not accept the lower-pressured incoming water. The manual information I posted, hopefully helped, as that was one of the possible errors listed. 🙂 Glad it’s all sorted out now.
