The DUO Sparkling Water Maker will only work with the 1L glass carafe and 1L Fuse bottle. If the carbonation head is not closing properly, check to make sure you are using the correct bottle. The DUO Sparkling Water Maker is not compatible with the 1L classic bottle, the 0.8L glass carafe, the 0.5L bottle, and My Only Bottle.
Still not closing or locking? Check the bottle holder inside the carbonating bottle flask. This piece is removable for easy cleaning and may become loose. To properly insert the bottle holder, twist it into the lower part of the flask.
