Why won't my carbonating flask close or lock?

Oh no! Let's first make sure you are using the correct bottle for your machine.

Please note that the DUO Sparkling Water Maker can be used with our dishwasher-safe 1L glass carafe and our regular 1L Fuse bottle. The 1L classic bottle, the 0.7L glass carafe (from the Crystal), the 0.5L bottle and My Only Bottle (0.5L) are not compatible.

  1. Place the DUO Sparkling Water Maker on a flat sturdy surface in an upright position and unlock the flask by turning the lever to the right. The carbonating head will rise automatically.
  2. Tilt the carbonating bottle flask forward to insert the bottle and return the flask to the upright position. Make sure the removable bottle holder is secured in place at the bottom of the carbonating bottle flask.
  3. Push and hold the carbonating head down, applying pressure as needed. Lock the flask by turning the lever to the left. When in the locked position, the flask lever will align with the small dot located beneath the SodaStream logo.
