A leaking SodaStream is very frustrating, I know all too well.
There’s really nothing more disheartening when you go to mix up a new soda, only to hear a hiss from its front or rear, signaling a leak.
This is even worse if you just bought a SodaStream machine and this is your first attempt.
But don’t worry, even if there’s a leak, the problem is usually something you can handle with a little investigation and a little elbow grease.
Other leaks have to do with the nozzle at the front.
Still, more might be an issue with water leaking from the bottle. These are usually issues with the shape of the bottle top. SodaStream machines are built to accept only certain types of bottle tops to form a seal for carbonation to occur.
Any tops that don’t fit this measurement will have a harder time working and may leak water and CO2 as a result.
In any case, you should always investigate leaks yourself to see if they can be fixed easily, as often its a minor assembly matter.
If they can’t, don’t forget that you might have an active warranty that can protect you from any manufacturer defects.
so you don’t have to buy a whole new machine that you just recently bought.
Carbonating Air Hose Leak
If your SodaStream isn’t making your drinks as fizzy as it is supposed to, we’d recommend opening the back of the machine.
Listen for a hissing sound. If such a sound comes from inside the carbonation canister, there might be an issue with the hose rather than the valve.
If you open up your drink maker machine, you might be confused.
After all, there doesn’t seem to be any real air hose visible.
The canister simply connects to a valve and nozzle on the interior of the machine which then leads the CO2 directly to the dispenser nozzle at the front of the device.
But there is an actual internal hose inside the canister.
This is the hose that connects the bottle to the nozzle itself, or what feeds CO2 from the bottle to the nozzle that then goes to the dispenser nozzle at the front.
If this hose is damaged or broken, you might not be able to use the canister.
You can take the canister apart and try to reattach the hose if it’s simply fallen off.
Alternatively, it is entirely possible the hose might be broken from either accidental dropping of the canister during shipment or in some cases a simple manufacturer error.
You can also buy a replacement hose from many home improvement stores.
They often have hoses of the right size and make.
It may also be easier to simply buy a new canister, but that depends on your own handiness with tools or willingness to fix a canister you already bought.
Carbonation Canister Leak
This is a far more common expression of a carbonation leak than the above example.
In this case, the canister itself might be broken from damage or from a manufacturer error.
Or the SodaStream itself might have been poorly or incorrectly assembled – it has been known to happen from time to time.
Whatever the case, the leak is coming from an improper seal in the valve that connects your carbonation canister to the drink maker machine. Identifying this is easy enough. Simply open the back of your machine, press a carbonating button, and listen.
Sometimes it’s as simple as a washer than needs fixing. Try to see if one of the sealing washers is loose and, if so, if you can reattach it with your fingers.
If you have washers lying around from other projects you’re doing, you might be able to use one of them and fit it atop the canister seal to make things work.
You might also find an issue with the SodaStream valve itself. One easy way to test this is to switch out the canisters if you have more than one.
If the leak persists, the issue is with your machine rather than the canister. But if it goes away, you know that the problem is really just with one individual container.
Either way, this problem requires some maintenance and work on the valve itself. If you aren’t comfortable working on that, you might need to contact SodaStream and see about the warranty.
We’ll explain more about that below.
Don’t forget to try twisting the valve to reseal it. Sometimes the leak is simply a matter of not having twisted things into place enough beforehand rather than a big mechanical error.
It would be a shame to go to all that effort when the solution was right in front of you!
You might also have an issue where your carbonation nozzle is leaking CO2.
This is distinct from the other two types of leaks, which happen at the back end of the soda maker.
This leak will be more audible and immediately noticeable.
You should hear a higher hiss than usual when you use the SodaStream to carbonate your next bottle of water.
In the first case, a CO2 leak could lead to your bottle being more carbonated than you intended. This can drain your reserves of CO2 too quickly. It’ll be pretty noticeably when your water bubbles a lot more vigorously than you like.
But if you remove the bottle and still hear a slight hissing, stick a finger near the carbonator nozzle and see if you feel a slight breeze.
If you do, that’s a sign that the nozzle is leaking CO2 constantly. Again, this wastes valuable fuel for your machine.
Fixing this is a bit tricky. Try to make sure the nozzle is fitted tightly into place. You can also try taking the front of the machine apart to determine where the leak is originating.
The valve that connects the nozzle to the canister may be weak. Try twisting it to make sure it is sealed properly.
OR possibly picking up a new nozzle – like this one on Amazon.
Alternatively, you might have water leaks from your SodaStream, rather than CO2 leaks.
A water leak comes from the bottle of water that you place beneath the carbonating nozzle. This can happen for a few reasons.
In one example, the bottle itself might be a poor fit.
Water leaks often happen if you don’t use the regular SodaStream bottles. These bottles have tops that are specifically designed to fit around the carbonating nozzle to receive carbonation.
While it’s possible that regular bottles have sizes that fit as well, it’s not as likely.
Also, Make sure you’re using these longer-lasting SodaStream bottles.
It may be the one you have is just at the end of its life!
Therefore, trying to force carbonation into a regular bottle could leave a small amount of space open between the top of the bottle and the carbonator. In this case, the water will likely splash over the edge of the bottle onto the surrounding table or counter.
It’s also likely that the end carbonation will be less impressive, as well. This is because some of the gas escaped through the same gap.
Even your regular SodaStream bottle might be having trouble.
These bottles can warp if they are plastic and have been exposed to extreme heat. The tops, if they warp, might not fit the carbonator nozzle the same way they used to. Like with regular bottles, this can leave a gap for both water and CO2 to escape during the process.
But it might be a deeper problem with your machine, as well. Like with the carbonation canister leak, try a few different bottles to determine what the issue is.
In these cases, checking out your warranty is a good idea. See the link above.
No matter which of these issues you have, it’s always a good idea to keep your warranty in mind.
The exact nature of the warranty and what it covers varies from type to type, but most SodaStream machines cover you in the event of a defect from the manufacturer.
That means that if your soda maker leaks from a defect in the build, you can get it repaired or replaced in most cases.
You should consult your instruction manual to check out your own warranty to see what’s covered.
This is cheaper and easier in many cases than trying to fix some of the more technical problems yourself.
However, be aware that the warranty doesn’t usually cover any damage that comes from you dropping or damaging the machine, or opening up and trying to fix it yourself.
If the damage is on you, it might also be up to you to enact your own home repairs to get things running smoothly again.…OR just consider an upgrade to your machine – like these featured SodaStream deals on amazon.
Good luck and I hope this guide helps you get your SodaStream leak diagnosed and fixed!
