Overflowing can be a common issue when using your SodaStream, but fear not! It’s easy to fix and even easier to prevent with just a few simple steps. In this article, we’ll guide you on how to stop your SodaStream from overflowing and ensure a smooth carbonation process.
SodaStream Overflowing Solving

Step 1: Avoid Shaking the Bottle
One of the main causes of SodaStream overflows is shaking the bottle after adding syrup or during the removal process. To prevent overflow, it’s recommended not to shake the bottle once it’s been carbonated. A gentle swirl should suffice to mix your syrup with the carbonated water.
Step 2: Don’t Overfill the Bottle
Another common reason for overflow is overfilling the bottle with water before carbonation. Always make sure your water level is up to the fill line, not beyond it. This ensures there’s sufficient room left for the gas to dissolve into the water, preventing any potential overflow.
Step 3: Ensure Proper Fitting
Misalignment or improper fitting of the SodaStream bottle can also lead to overflows. Make sure your SodaStream bottle is fitted correctly onto the machine. The bottle should be screwed in securely and straightly to avoid any leakage or overflow.
SodaStream Overflowing Additional Tips:
- Only carbonate water in your SodaStream. Carbonating other liquids can cause the machine to overflow and potentially damage it.
- If your SodaStream continues to overflow despite following these steps, it might have a clog or a damaged gasket. In this case, you may need to seek professional help.
- Check if the nozzle is fully inserted into the clear plastic carbonation bottle. Sometimes, the SodaStream may leak during carbonation if the nozzle is not fully inserted.
- Make sure the carbonation canister is set firmly. Excess gas leaving the machine can be a sign of worn-out washers or a canister that’s not screwed in enough.
Remember, always follow the manufacturer’s instructions while using your SodaStream. This will not only prevent any issues like overflow but also ensure the longevity of your machine. Happy carbonating!
Why does my SodaStream spray water everywhere?

Your SodaStream might be spraying water everywhere due to a few possible reasons:
- Overfilling: If you fill your bottle past the fill line, it can cause water to spray out during carbonation. Always make sure to fill your water up to the indicated line.
- Carbonating Too Quickly: If you press the carbonation button too quickly or too many times, it can cause the water to spray. Try pressing the button in a more controlled and slower manner.
- Shaking the Bottle: Shaking the bottle before or during the carbonation process can cause water to spray out. After you’ve added your flavorings, gently swirl the bottle to mix them instead of shaking it.
- Faulty Bottle: If your bottle is damaged or not properly screwed onto the machine, it can cause water to leak or spray out. Check the condition of your bottle and ensure it’s properly attached.
- Carbonating Non-Water Liquids: SodaStream machines are designed to carbonate water. If you’re trying to carbonate other liquids, it may cause the machine to overflow or spray water.
If you’ve checked all these points and your SodaStream is still spraying water, it might be best to contact SodaStream’s customer service for further assistance.
Why is my SodaStream not sealing?

If your SodaStream is not sealing properly, it could be due to a few potential issues:
- Faulty Bottle: The bottle might be damaged or worn out. Over time, the seal on the bottle cap can wear down, preventing it from sealing correctly. In this case, you might need to replace the bottle.
- Improper Attachment: Make sure that the bottle is correctly attached to the machine. It should be screwed in securely and straightly. If it’s misaligned or not screwed in properly, it may not seal as it should.
- Damaged Machine: The machine itself might have a problem. If the part of the machine where the bottle screws in is damaged or worn out, it could prevent a proper seal.
- Incorrect Use: Ensure you’re using the machine correctly. Only carbonate water, and make sure the water is cold before carbonation. Also, do not overfill the bottle past the fill line.
- Worn-out or Damaged Seal: The seal in the machine that helps close the system for carbonation could be worn out or damaged. If this is the case, it might need replacing.
If you’ve checked all these points and your SodaStream is still not sealing properly, it might be best to contact SodaStream’s customer service or a professional for further assistance.
How can I prevent my Fizzi from water leakage?

Here are a few steps to resolve the issue if your Fizzi is leaking water:
- Check the Bottle: Make sure the bottle is not damaged or worn out. If it is, you might need to replace it.
- Ensure Proper Attachment: Confirm that the bottle is correctly attached to the machine. It needs to be screwed in securely and straight. If it’s misaligned or not properly attached, it could lead to leaks.
- Inspect the Machine: If the part of the Fizzi where the bottle screws in is damaged, it may not seal properly, causing a leak. Check this area carefully.
- Use Correctly: Only carbonate cold water, and do not overfill the bottle. Overfilling or trying to carbonate other liquids could lead to leaks.
- Examine the Seal: The seal in the machine helps close the system for carbonation. If it’s worn out or damaged, it might need to be replaced.
- Using the correct type of water bottle with your SodaStream machine is crucial to ensure its proper functioning.
The Fizzi model is compatible with several types of bottles, including:

- 1L Slim Bottle: This sleek and slim design is perfect for on-the-go hydration.
- My Only Bottle: This personal-sized bottle is ideal for individual use.
- 0.5L Bottle: This smaller-sized bottle is great for a quick refreshment.
- 1L Classic Dishwasher-Safe Bottle: This durable bottle can be conveniently washed in the dishwasher.

Remember, always ensure the bottle is securely attached before carbonation, and only fill up to the indicated line to prevent leaks or overflows.
Why is gas coming out the top of my SodaStream?

Experiencing gas coming out of the top of your SodaStream can be due to a few reasons:
- Leaky Cylinder: If your cylinder is leaking gas, it’s advised not to remove the bottle and cylinder or continue pressing the carbonating button.
- Bottle Not Fully Attached: If the SodaStream’s nozzle is not fully inserted into the clear plastic carbonation bottle, the device might leak gas.
- Insufficient Pressure: If there’s not enough pressure, the seal won’t go down far enough, resulting in gas escaping and poor carbonation.
- Wrong Bottle: Using a bottle that doesn’t fit your machine well can cause gas leakage. Always use the intended SodaStream bottles for your specific model.
- Poor Sealing of the Valve: A poor sealing of the valve that connects the carbon dioxide bottle to the beverage dispenser can also cause a leak.
- Internal Carbonation Air Hose Issue: If you are hearing a hissing noise coming from your SodaStream, the carbonation tube could be leaking gas, or the carbonation bottle might be leaking.
- Issues with Washers or Valve Plunger Type: If you have two washers inside the receptacle which receives the refill’s threaded valve, remove one. The additional depth of two washers prevents the valve’s plunger from being fully depressed. Also, SodaStream refills come with two types of valves. One requires a just little bit more than “hand tight” to activate (one hand needed). The second type requires SIGNIFICANTLY more turning effort to activate (two hands needed).
If you’re experiencing any of these issues, it’s important to address them promptly to prevent further problems with your SodaStream.
Can you over carbonate with SodaStream?

Yes, it is possible to over carbonate with a SodaStream. Over carbonation can happen if you press the carbonation button too many times or too quickly. This can result in excess pressure that might cause the water to spray out or the bottle to overflow. Additionally, over carbonation may also lead to a sharper, more acidic taste which some people might find unpleasant.
SodaStream recommends carbonating until you hear the loud buzz, and not going beyond three buzzes for optimal carbonation. Always remember to use cold water and not to overfill your bottle to ensure the best results.
Why is my SodaStream not carbonating properly?
If your SodaStream is not carbonating properly, here are some potential reasons based on the information I found:
- Incorrect Carbonation Technique: According to SodaStream Support, you should carbonate by pushing down firmly on the carbonating button for around 2 seconds, releasing, and repeating. Do this 3 times for light fizz, and 5 times for strong fizz.
- Loose Cylinder: The cylinder may not be tight enough. If you’re not getting bubbles, try retightening the cylinder by twisting it to the right.
- Wrong Water Temperature: The temperature of the water you’re using can affect carbonation. Warm water generally results in fewer bubbles. For optimal carbonation, use cold water.
- Carbonating Air Hose Leaks: If your drinks aren’t being carbonated as they should, there could be a leak in the carbonating air hose.
- Improper Bottle Installation: The most common reason for lack of fizz is that the carbonating bottle hasn’t been installed correctly at the base of the water maker. Check to ensure it’s properly installed.
- Low CO2 Levels: If your SodaStream isn’t carbonating enough, check your CO2 levels. You might need to refill or replace your CO2 cylinder.
- Overfilling the Bottle: Overfilling your soda bottle higher than the designated “fill” line can cause trouble and result in the SodaStream bubbling over.
Remember, only water should be carbonated in the SodaStream Sparkling Water Maker. If you’ve already prepared a drink with flavor, you cannot recarbonate it.
How many times do you press SodaStream?

The number of times you press the button on your SodaStream depends on the level of carbonation you prefer. Generally, SodaStream recommends pressing the carbonating button in short bursts until you hear a buzz.
- For a light fizz, press the button until you hear three buzzes.
- For a medium fizz, press the button until you hear five buzzes.
- For a strong fizz, press the button until you hear seven buzzes.
Remember to press the button firmly and release it between each press to allow the gas to be absorbed into the water. It’s also important not to overdo it as over-carbonation can cause the water to spray out or the bottle to overflow. Always use cold water for the best results.
