Not sure if your CO2 cylinder is empty?
- Make sure the cylinder is tight enough and retighten if necessary by twisting it to the right.
- If you're still not getting enough bubbles and if you don't hear a sputtering sound when you press the carbonating button, you may be out of gas.* You can get a new cylinder through our online exchange program or a participating retail location.
*In 2020, we upgraded the Aqua Fizz Sparkling Water Maker with a new, silent valve. In these Sparkling Water Makers, it is normal to not hear a sputtering sound and is not an indication of the amount of CO2 left in the cylinder.
