If you are panicking about your faulty SodaStream machine, it’s proof that you love sparkling water so very much. Don’t worry. Now that you are here, we will help you fix it and get your home soda maker up and running in no time!

Common SodaStream Problems and How to Fix Them

The idea of making your own soda at home is just so convenient. Instead of buying calorie-filled drinks, you have total control of what’s in them. We have to admit that watching your water bubble is also fun! But sometimes, just sometimes, carbonating water with your SodaStream may go wrong. In this case, understanding common SodaStream problems can help you diagnose the issue and fix it quickly.

Your SodaStream, just like any other kitchen appliance, can malfunction at some point. The fault can be with the carbonation process or the end result itself. It can be frustrating, especially if it happens when you most need it, like for a family dinner or children’s party. The good news is that most issues are common and quickly resolved. 

That said, proper knowledge is key, and it’s vital to follow the steps accurately to solve the problem. So, before you panic, let’s go over different scenarios of common SodaStream problems and how to fix them effectively. Fingers crossed! 

But, first things first.

Getting in Touch with SodaStream

If you think the issue is serious or have been encountering the same issue repeatedly, trying to claim your warranty under valid circumstances is the best idea. So, before you start flexing your DIY skills, let’s get to the easiest way to resolve some of the common problems.  

What am I doing wrong with my SodaStream?

Knowing how to use a SodaStream properly is vital to the longevity of the machine. So, make sure you read the SodaStream instructions well before setup and usage. If the home soda maker is not handled properly or cleaned regularly, issues can pop up. 

However, it’s not always user errors that lead to problems. Sometimes, it could be a problem with the machine itself. Despite the great reputation, SodaStream machines can and do malfunction. If you think the issue is due to a manufacturing defect and/or failure then we advise you to get in touch with the SodaStream support team.

Can a SodaStream be repaired?

Suppose your SodaStream malfunctions within the warranty period, and it is determined that the problem is due to faulty workmanship or materials, SodaStream will send you a replacement of new or comparable value, free of charge.

What is the Warranty on SodaStream Machines?

What is the warranty on SodaStream? Under normal home use, SodaStream provides a  2 (two) years limited warranty following the date of purchase. Remember to register your SodaStream online by visiting

If your SodaStream machine is outside of the warranty period and you would like to save money on the purchase of a new machine then read on as we have some simple fixes for common problems that should have you making your favourite sparkling water in no time.

Why is my SodaStream not carbonating?

Carbonation issues probably top the list of common SodaStream problems but they can be resolved most of the time. If your SodaStream is not releasing CO2, it can be due to,

  • The cylinder is not being screwed on properly

If the CO2 cylinder is not installed correctly at the base of the machine, it won’t pump gas effectively. The models compatible with SodaStream’s blue-coloured cylinder with a thread mechanism can often encounter this issue if they are not fitted properly. In this case, unscrew your tank and screw it back on. With the Quick-connect cylinder (pink colour), ensure the bottle is placed firmly in the holder, and the handle is fully locked down.

  • Your SodaStream cylinder is out of gas

If the cylinder is in place correctly and the SodaStream still gives no fizz, then the canister is probably out of CO2. One way to check and verify inadequate carbonation is by pressing the button on top of the valve. If you hear gas escaping, it means that it’s too empty to work and needs to be replaced. In this case, you need to replace it or get it exchanged. 

Please ensure you exchange the right carbonator for your particular SodaStream machine. Click on the correct cylinder colour below.

Alternatively, a blocked nozzle can also be the cause of SodaStream not carbonating, and we have a detailed guide on how to clean your nozzle and get the machine up and running in no time! 

Why is my SodaStream sparkling water flat?

Now, we know that bubbles indicate that your water is being carbonated. But, in some SodaStream models, like the Aqua Fizz, where the bottle is enclosed by the machine, it’s not visible. In this case, if your water turns flat, check if the canister has gas left.

Another reason could be insufficient CO2 pumped into the bottle. Most SodaStream models allow you to customise the carbonation level, and your water is likely to stay fizzy for a longer time if you pump more CO2. So, try it once more, this time giving some additional presses. 

If your water turned flat sometime after carbonation, it could be due to loss of pressure. The higher the pressure, the more CO2 it holds, the fizzier it will be. For example, if you leave an open bottle of carbonated water on your table, it will go flat. If you cap the bottle, it will maintain carbonation but also build up pressure in the bottle. Please read this article on the compressed chemistry of carbonation to better understand the role of carbonation in your sparkling water.

Why is my SodaStream Not Carbonating Water Properly, Even Though CO2 Is Being Released?

If the canister has adequate CO2 and you have pumped enough CO2 to get that tingly taste of sparkling water, but the output is still not as good as you want it to be, the issue could be due to the following reasons. 

  • You are carbonating other liquids

If you try to carbonate liquids other than water, even if it’s just flavoured water, the carbonation result won’t be as good as you want them to be. It can also damage the machine. This is because SodaStream home soda makers are only for carbonating plain water, and other ingredients can affect the efficacy of CO2 absorption. 

  • You didn’t use cold water

Cold water is generally recommended for carbonating water because it can absorb CO2 better and retain it longer. So, if you have used lukewarm or warm water, it could be the culprit that makes your water lose its sparkle too soon! 

  • You detach or open the bottle too soon

Allow your sparkling water to rest after carbonation. Once you have carbonated your water, please don’t open the SodaStream bottle as soon as you are finished. Let it rest for about 45 seconds. This allows the CO2 gas to dissolve in the water completely.

  • The carbonation bottle is not properly positioned

Check your SodaStream bottle. If your SodaStream bottle isn’t fitted tightly onto your SodaStream, it will lose gas, and your water won’t carbonate well. Alternatively, you should also ensure your SodaStream machine is leak proof as we have explained below.

Why is my SodaStream leaking gas during carbonation?

One of the major problems with SodaStream machines is gas leaks during carbonation. A hissing noise is what usually indicates a gas leak, and in this case, check for,

Carbonation Canister Leaks: Check the carbonation canister. If this is not properly inserted, it will leak. Make sure that the canister is screwed in (BLUE) or pushed all the way in (PINK) to the machine. (BLUE) should be tight and you should hear a click (PINK) when it is properly inserted.

Carbonating Air Hose Leaks: The next thing you should check is the carbonating air hose. If this hose is not properly attached, it will leak. To fix this problem, simply reattach the hose and make sure that it is tight.

In some cases, the leak won’t be so obvious. If you find your water not carbonated adequately or overflowing during carbonation, it can also be a sign of a leak. Here are some other problems that may be causing it.

Broken Seal Leak: There’s a rubber seal fitted to the soda maker’s nozzle to prevent leaks during carbonation. If the seal is loose, worn out, or broken, it can leak gas. In this case, you either have to remove the seal and put it back again or replace it with a new one. If the seal is not tight, gas will escape. Here’s how to do it right

Nozzle Leaks: If the nozzle is not properly attached, it will leak. To fix this problem, simply reattach the nozzle and make sure that it is tight.

Why is my SodaStream Leaking Water During Carbonation?

More often than not, a gas leak can cause water to leak or overflow during the bubbling process. However, it can be due to other reasons too. Here’s how to troubleshoot common SodaStream problems causing leaks and fix them right!

  • Check for a loose seal

We mentioned above that a broken or loose seal/washer can cause gas leaks. This washer forms a tight seal between the bottle and the machine. So, a faulty washer can cause water to leak or overflow, especially if it leads to over-carbonation. Follow the steps above to resolve the issue!

  • Check if the bottle is screwed on or positioned correctly

If the bottle is not in position or is off-thread, it can lead to water leaking or overflowing during carbonation. Make sure that the bottle is pushed all the way into the machine and is screwed on tightly. You should hear a click when it is properly inserted, and won’t be able to unscrew it by hand.

  • Check if water is filled up to the fill line

It’s important to ensure the bottle is not under-filled or over-filled. You will find the SodaStream not carbonating properly if the starting liquid level is too low. There should be at least 10 cm (4 inches) of water in the bottle in order for it to work correctly. Similarly, going over the fill line can cause water to overflow. 

Why is my SodaStream Carbonation Button Not Working?

A faulty button can also be the cause of SodaStream not working properly. The button on your SodaStream is made of plastic (ABS), and plastic tends to depreciate with time and frequent usage. As a result, your SodaStream Carbonation Button may stop working sooner than anticipated, depending on how often you use the machine. When the button wears out, you’ll notice that you’ll have to press it with more force to have the machine react at all. 

Although this issue is a bit challenging, you can try to fix it using a couple of methods. Check out the videos below for instructions! In unfortunate cases it breaks, it will stop working, and in this case, it could be time to replace your home soda maker with a new one.

Why does my SodaStream Sparkling Water Taste Weird?

Well, that’s frustrating. Now, where did the SodaStream system go wrong this time? Two things can be the culprits that cause your soda water to taste weird.

  • Residue in carbonation bottles

If you don’t clean your SodaStream bottles and their caps after carbonating water every time, it can lead to the growth of bacteria, mould, or buildup. Yes, it’s the case, even if you are carbonating ‘just’ water. So, make sure you wash them and let them dry completely before storing them for the next use. 

SodaStream bottles are hand-washed only (except for the models with glass carafes), but they are easy to clean as you won’t have been carbonating different liquids in them. Clean using lukewarm water and mild dishwashing solution. Use a suitable Cleaning Brush if necessary.

Cleaning these PET bottles with abrasive cleaning tools or harsh cleaning solutions can damage the surface of the bottle and the small gaps it creates can be a breeding ground for mould or bacterial growth. So, don’t overdo it either! Read our guide on how to clean your SodaStream Bottles here.

  • Clogged nozzle

We have covered this in the section below!

Why is my SodaStream Nozzle Clogged?

Can a SodaStream get clogged? Absolutely. A clogged or dirty nozzle is one of the common SodaStream problems users face. But, don’t worry. If the nozzle of your machine becomes clogged, a quick, thorough, proper cleaning can fix the problem in no time. Click here to read our helpful in-depth cleaning guide.

Why is the Loader Tab of my SodaStream Immobile ?

When pressure is applied to the lever of the SodaStream, it does not move. In this case, check to ensure that the tab is not damaged. If the tab is bent or damaged, it will need to be replaced. It is also possible that there is something blocking the pathway of the tab. Remove any objects that may be in the way and try again. Alternatively, try the following.

  • Correcting the Starting Angle and Position

When you start to carbonate your water, the machine makes a loud noise and does not seem to be working correctly. This is usually caused by an incorrect starting angle. The Sodastream machine must be started at a 45-degree angle. If it is not started at this angle, the machine will not work correctly.

  1. You may have started with an incorrect angle. Be sure that the nozzle and tab are both angled away from the SodaStream machine before the bottle is inserted.
  2. The tab may have gotten caught if you did not follow this initial step.
  3. The SodaStream manual states that if you cannot pull the loader tab, you should ensure that the carbonating block is fully upright and upward.
  4. Be gentle so the tab doesn’t suffer any undue damage, which may further complicate your dilemma.
  • Inserting and Removing the Bottle
  1. Make sure that the carbonating block is in its fully upright position.
  2. Gently pull the loader tab toward you until it clicks.
  3. Insert the bottle into the snap-lock at the correct angle.
  4. Firmly push the bottle up and back until it locks into place.
  5. To remove your bottle, make sure that your carbonating block is still in its correct position, and pull the bottle toward you.
  6. Avoid doing this roughly as you may damage the bottle and machine if you’re too aggressive.

Why is my Electric Powered SodaStream unresponsive?

Unresponsive machines and blinking buttons are common SodaStream problems for models powered by electricity such as the E-Terra. Here are a couple of things you can try!

  • If your SodaStream system isn’t turning on at all, it could be a loose connection. Attach and detach the power cord and try again. Also, make sure the power outlet is working.
  • If your SodaSteam is not working and lights are flashing, unplug the cord from the power source and remove the cord from the machine. Then remove the CO2 cylinder, put it back in, attach the cord again, and try running the machine. 
  • If the machine is still unresponsive, there might be an issue with the power cord or the outlet. We recommend you hire a professional to figure out the issue, or better yet, contact SodaStream and get a replacement if possible. 

Additional Tips to Resolve Common SodaStream Problems

  • Only carbonate water in your SodaStream and add your preferred flavours afterward to avoid damaging the machine and making a big mess!
  • Always wipe down your SodaStream after usage, including the nozzle, and cover or place it in a safe area to prevent dust and dirt build-up. Make sure the bottles and the machine’s exterior are completely dry before storing them. 
  • Remember to replace your plastic SodaStream bottles every 3-4 years. You can find the expiration date on the bottle, and using it further can be dangerous to the machine as well as the user. 
  • If you need extra carbonation to make your water as fizzy as possible, we recommend filling water slightly below the fill line.
