Is your SodaStream not fizzing the way you want it to? It could be a sign that your CO2 cylinder is running low. In this article, we’ll explore how to identify if your SodaStream gas canister is empty, and what steps you can take in response.

So, let’s dive right into the bubbly world of carbonation!

Signs that Your SodaStream Cylinder is Empty

How To Know When Sodastream Is Empty (1)

There are a few key signs that indicate your SodaStream cylinder is empty, such as a lack of carbonation in your beverages and the gas not being released when you press the carbonation button.

Additionally, if the carbonation button stays down without any bubbles being produced, it’s a clear indication that your cylinder needs to be replaced.

Lack of carbonation

Flat drinks are a clear sign that your SodaStream cylinder is running low on gas. This happens because carbonation gives sodas their tell-tale fizz, and this fizz comes from CO2 gas in the cylinder.

Think of when you’ve poured yourself a soda and it doesn’t have that usual bubbling effect or zesty taste; it’s likely due to lack of carbonation. A similar experience occurs with your SodaStream machine when the canister becomes depleted of CO2.

The beverage produced lacks its usual effervescence or sparkle, which indicates that there’s not enough gas left to properly carbonate your drink.

Lighter weight

If your SodaStream cylinder feels surprisingly light, it could be a sign that it’s empty. When the gas inside the canister is used up, the weight of the cylinder will decrease noticeably.

So if you pick it up and it feels lighter than usual, it’s time to think about getting a refill. Don’t worry though, checking the weight is just one of several ways to determine if your carbonating cylinder needs replacing.

Gas not being released

If you’re finding that your SodaStream isn’t carbonating your drinks like it used to, there’s a chance that the gas in your cylinder has run out. One of the signs of an empty SodaStream cylinder is when the gas is not being released properly.

When you press down on the carbonation button, you may notice fewer or no bubbles forming in your drink. This lack of fizz indicates that it’s time to replace or refill your gas cylinder.

Checking for this sign can help ensure that you always have a fresh and carbonated beverage at hand. So if you’re experiencing a decrease or absence of bubbles when using your SodaStream, it’s likely because the gas needs to be replenished.

Carbonation button stays down

The carbonation button on your SodaStream machine stays down when the cylinder is empty. This means that no gas is being released into the water, resulting in a lack of carbonation.

It’s an obvious indicator that it’s time to replace or refill your gas cylinder. Remember to always check the weight of the cylinder as well to confirm if it is empty.

How to Test if Your SodaStream Cylinder is Empty

To determine if your SodaStream cylinder is empty, you can perform simple tests like checking the weight or unscrewing the cylinder to compare it with the TARE weight. If you’re still unsure, try a carbonation test.

Keep reading to learn how to perform these tests and ensure you never run out of sparkling beverages again!

Unscrew and check weight

To determine if your SodaStream cylinder is empty, you can unscrew it and check the weight. A lighter weight than usual could indicate that the cylinder is running low on gas or may be completely empty.

By comparing the weight of the cylinder to its TARE weight (the weight of an empty cylinder), you can easily tell if it needs a refill.

Compare weight to TARE weight

To determine if your SodaStream cylinder is empty, you can compare its weight to the TARE weight. Simply unscrew the cylinder from your Sparkling Water Maker and check its weight on a scale.

The TARE weight is the empty weight of the cylinder without any gas inside. If the current weight of your cylinder is significantly lighter than the TARE weight, it’s a good indication that it may be empty and in need of a refill.

Comparing weights can be an easy and effective way to monitor the gas levels in your SodaStream cylinder.

Perform a carbonation test

To perform a carbonation test, simply fill a glass with cold water and attach your SodaStream bottle. Press the carbonation button to release gas into the water. If you see bubbles and hear the sound of gas being released, then your cylinder is still functioning properly.

However, if there are no bubbles or you don’t hear any gas being released, it may be an indication that your SodaStream cylinder is empty and needs to be replaced.

Common Questions and Concerns

How long does a SodaStream cylinder last?

A SodaStream cylinder can last for several weeks or even months, depending on your usage. The duration of a SodaStream cylinder largely depends on how often you use it and the amount of carbonation you prefer in your beverages.

If you use your SodaStream frequently and enjoy highly carbonated drinks, then the cylinder may not last as long compared to someone who uses it occasionally and prefers lighter carbonation.

It’s always a good idea to keep track of your usage and have a backup cylinder handy so that you never run out of sparkling water when you need it most.

Can you refill a SodaStream cylinder?

Yes, you can refill a SodaStream cylinder. When your SodaStream carbonator is empty, you have the option to exchange it for a full one at participating retail locations or order a refill online.

This way, you can continue enjoying your sparkling beverages without any interruption. Refilling your cylinder is easy and convenient, ensuring that you always have carbonation on hand whenever you need it.

Keep in mind that when refilling, it’s important to follow the manufacturer’s instructions and safety guidelines to ensure proper handling of the CO2 canister.

What to do when the carbonator is empty

If you find that your carbonator is empty, don’t panic! There are a few simple steps you can take to get it back up and running. First, remove the empty carbonator from your SodaStream machine by unscrewing it from the back panel.

Next, retighten any loose connections and make sure everything is properly aligned. Finally, replace the empty carbonator with a full one by following the manufacturer’s instructions.

With these easy steps, you’ll be enjoying sparkling water again in no time!

Tips for Maintaining and Monitoring Your SodaStream Cylinder

Keep a record of your usage and refills, regularly check the weight of the cylinder to ensure it is not empty, and handle and store it properly to prevent any damage or accidents.

Keep track of usage and refills

To ensure that you never run out of carbonation, it’s important to keep track of your SodaStream usage and refills. By monitoring how often you use your sparkling water maker and keeping a record of when you last replaced the CO canister, you can stay ahead of any potential issues.

This way, you’ll always have fresh bubbles at your fingertips whenever you want a refreshing drink. Make it a habit to check the gas cylinder regularly and plan for refills accordingly.

With this simple step, you’ll never be caught without carbonation again!

Regularly check the weight of the cylinder

To ensure that your SodaStream cylinder doesn’t run out unexpectedly, it’s crucial to regularly check its weight. Simply unscrew the cylinder from the sparkling water maker and lift it up to assess its weight.

A lighter weight indicates that the gas is running low or might already be empty, so it’s time for a refill. By proactively monitoring the weight of your cylinder, you can avoid any fizz emergencies and keep enjoying refreshing carbonated beverages whenever you want them.

Properly store and handle the cylinder

To ensure the safe and effective use of your SodaStream cylinder, it is important to properly store and handle it. Always keep the cylinder in an upright position and away from heat sources.

Make sure to securely tighten the cylinder onto your sparkling water maker to prevent any leaks. When not in use, store the cylinder in a cool and dry place. Additionally, avoid dropping or mishandling the cylinder to prevent damage or accidents.

Properly storing and handling your SodaStream cylinder will help prolong its lifespan and ensure optimum performance when carbonating your beverages.


In conclusion, knowing when your SodaStream cylinder is empty is important to ensure you always have access to sparkling water or carbonated beverages. By paying attention to signs like lack of carbonation and lighter weight, as well as performing simple tests like checking the weight and performing a carbonation test, you can easily determine if it’s time for a refill.

Maintaining and monitoring your cylinder’s weight regularly will help you stay prepared and enjoy fizzy drinks whenever you want them.
