Why Is My SodaStream Jet Not Fizzy?

The SodaStream Jet is a popular home carbonation system that allows you to make your own sparkling water at home. However, you may encounter situations where your SodaStream Jet fails to produce fizzy carbonated water. In this article, we will explore the possible reasons behind this issue and provide you with troubleshooting tips to help you fix it.


The SodaStream Jet operates by injecting carbon dioxide (CO2) gas into water, creating carbonation and giving your water a refreshing fizz. When your SodaStream Jet is not producing fizzy water, it can be frustrating. There are several factors that can contribute to this problem, including:

  1. CO2 Cylinder: The CO2 cylinder provides the carbonation for your water. If the cylinder is empty or low on gas, it can result in weak or no carbonation.

  2. Carbonation Level: The carbonation level setting on your SodaStream Jet determines the amount of CO2 injected into the water. If the carbonation level is set too low, it can result in less fizzy water.

  3. Water Temperature: The temperature of the water can affect the carbonation process. Cold water holds carbonation better than warm water, so using chilled water can help achieve a fizzier result.

  4. Bottle Seal: A proper seal between the bottle and the SodaStream Jet is essential for carbonation. If the bottle is not securely attached or the seal is damaged, it can lead to a loss of carbonation.

Troubleshooting and Fixes

If your SodaStream Jet is not producing fizzy water, here are some troubleshooting steps you can take to identify and fix the issue:

  1. Check the CO2 Cylinder: Ensure that the CO2 cylinder is not empty or low on gas. Replace the cylinder if necessary.

  2. Adjust Carbonation Level: Increase the carbonation level setting on your SodaStream Jet to achieve a higher level of carbonation. Experiment with different settings to find your preferred level of fizziness.

  3. Use Chilled Water: If you are using tap water, try chilling it in the refrigerator before carbonating. Cold water holds carbonation better and can result in a fizzier drink.

  4. Check Bottle Seal: Make sure the bottle is securely attached to the SodaStream Jet and that the seal is intact. Inspect the bottle for any damage or wear that may affect the seal. Replace the bottle if needed.

  5. Clean the Nozzle: Over time, the nozzle of the SodaStream Jet can become clogged with mineral deposits or debris. Clean the nozzle using warm water and a soft brush to ensure proper carbonation.


In conclusion, there are several factors that can contribute to your SodaStream Jet not producing fizzy carbonated water. By checking the CO2 cylinder, adjusting the carbonation level, using chilled water, ensuring a proper bottle seal, and cleaning the nozzle, you can troubleshoot and fix the issue. Enjoy your homemade fizzy drinks with a properly functioning SodaStream Jet!

Frequently Asked Questions

Q: How long does a CO2 cylinder last in a SodaStream Jet? A: The lifespan of a CO2 cylinder depends on usage, but on average, it can carbonate approximately 60 liters of water.

Q: Can I use other types of water with the SodaStream Jet? A: Yes, you can use various types of water, including tap water, filtered water, or even flavored water, with the SodaStream Jet.

Q: Why is my carbonated water losing its fizz quickly? A: Carbonated water can lose its fizz over time due to factors such as temperature changes, improper bottle sealing, or extended exposure to air. Ensure proper storage and sealing to maintain carbonation.

Q: Can I carbonate beverages other than water with the SodaStream Jet? A: It is recommended to carbonate only water with the SodaStream Jet. Carbonating other beverages may cause damage to the machine or result in messy spills.

Q: Can I refill my CO2 cylinder instead of buying a new one? A: SodaStream offers a cylinder exchange program where you can exchange your empty cylinder for a full one at participating retailers. Refilling cylinders yourself is not recommended for safety reasons.

Q: Why is my SodaStream Jet making a loud noise during carbonation? A: A loud noise during carbonation is normal and indicates that the CO2 gas is being released into the water. However, if the noise is excessively loud or accompanied by other issues, it is advisable to contact SodaStream customer support.

Remember to always refer to the user manual provided with your SodaStream Jet for specific instructions and safety guidelines.
