Why is my SodaStream DUO™ not carbonating properly?

Let's help you get back to bubbling:

Step 1 - Is your bottle compatible with SodaStream DUO™?

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

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?

After pressing the carbonating button a few times, check if you see bubbles. If you don’t, you may be out of CO2. You can get a new cylinder through a participating retail location or online.

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

Step 3 - Is your SodaStream Quick Connect Cylinder properly installed?

*** Please note - the cylinder handle might be either Black or Pink ***

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

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

Do not carbonate if flavours were added!

To carbonate, push the carbonating button down firmly for ~2 seconds, release, and repeat.

Repeat 3 times for light fizz, 5 times for strong fizz, and more for extra strong fizz.
