Why is my SodaStream Genesis™ Sparkling Water Maker not carbonating properly?

Let's help you get back to bubbling:

Step 1 - Is your carbonating bottle compatible with SodaStream Genesis™ Sparkling Water Maker?

The SodaStream Genesis™ Sparkling Water Maker is compatible with the 0.5L carbonating bottle (My Only Bottle), the 1L classic carbonating bottle, the 1L Fuse bottle, and the 1L classic dishwasher-safe bottle.

Check the following compatibility chart:

If you’re using the correct bottle and still unable to carbonate, follow the below instructions for further assistance:

Step 2 - Are you out of CO2?

If you're still not getting bubbles and if you don't hear a sputtering sound when you press the carbonating button, you may be out of CO2. You can get a new cylinder through a participating retail location or by online CO2 order.

If you’re not out of CO2, follow the below instructions for further assistance:

Step 3 - Is your SodaStream Screw-In System Cylinder properly installed?

  • Make sure the cylinder is tight enough and retighten it if necessary by twisting the cylinder to the right.


Step 4 - Did you fill the carbonating bottle to the fill line?

Step 5 - Did you fizz the water in the right way?

Do not carbonate if flavors were added!

Carbonate by pushing down firmly on the carbonating button for around 2 seconds, release, and repeat -- 3 loud buzzes will produce a standard fizz, additional presses will produce a stronger fizz. When you've reached the right carbonation level, gently pull the bottle towards you and twist it to the left to remove.
