SodaStream Source Troubleshooting

This troubleshooting page will help you address problems to better operate your SodaStream Source.

Soda is not Fizzy Enough ¶ 

Finished soda is flat, it does not have enough bubbles.

Water Temperature is Incorrect ¶ 

Using warm water generally results in fewer bubbles. Cold water is recommended for best results.

Start with Carbonated Water ¶ 

Using carbonated water, that is unflavored, will result in more bubbles. You will be adding additional carbonation and the soda will have more overall fizz.

The Loader Tab is Immobile ¶ 

When pressure is applied to the lever, it does not move.

Incorrect Starting Angle ¶ 

The nozzle and tab should be angled away from the SodaStream before the bottle is inserted. The tab may be caught, try gently lifting the tab away from the body of the machine.

Hear Gas Escaping ¶ 

You hear a high pitched noise coming from your machine

Carbonation Canister is Loose ¶ 

If the Carbonation canister is not set firmly, you may hear excess gas leaving the machine. This can be caused by having worn out or too many washers, or if the canister is not screwed in enough. Make sure the canister is securely fastened before and after use.

*Note: Recent carbonation bottles have been recalled due to the possibility of bursting under pressure. If this issue of gas escaping occurs, and your bottle was purchased between Feb. 2016 and Jan. 2017, consider changing out the canister and checking if your bottle was part of the recall.

Gas Tube is Loose ¶ 

The 2" long white gas tube on some models can become loose. This is located in the connection area and goes inside your bottle. You will feel the CO2 escaping as you press the lever on the top of the machine to dispense the gas. Tighten down and proceed as normal.

SodaStream is Unresponsive ¶ 

When trying to operate the SodaStream, nothing happens.

Too Many Sealer Washers ¶ 

If there are too many washers present the carbonation bottle will not be able to hold in place. Be sure to check the carbonation attachment area with tweezers. If you pull out one little black rubber ring and there is a second one present underneath, leave the second one and keep the extra one for future use.

Washer Needs to be Replaced ¶ 

After time, the sealer washer can become less firm in the carbonation attachment area. This will cause the carbonation bottle to shift or not hold firm once attached. To change, take a pair of tweezers and pull the little black rubber ring out of the area where the carbonation bottle attaches to the SodaStream. Replace this with another washer and try to reattach the carbonation bottle. If the bottle holds firm the machine should respond once again.

Nothing Turns On ¶ 

If you are trying to use your SodaStream, and nothing is happening (i.e. there are no lights on your three-level carbonation indicator), you may need to replace the battery or interface chip located within the carbonation button on the front of the machine. See our guide for instructions.

Leaking during carbonation ¶ 

When the SodaStream is operating, there is leaking around the opening of the soda bottle.

Bottle is not in Correct Place ¶ 

Make sure the bottle is completely upright. The carbonation nozzle has downward force and may spray if the bottle is inserted at an angle.

Bottle is not Fully Attached ¶ 

The nozzle must be fully inserted in the clear plastic bottle to avoid leaking. When inserting the bottle go in at an angle, screw in the bottle, then gently push the lever.

Incorrect Starting Liquid ¶ 

Always use water or unflavored carbonated water with your SodaStream. Using other liquids such as juice or a soda that has gone flat you risk damaging your SodaStream. Using other liquids may result in a fizzy mess.

Have recently swapped gas bottle. New bottle is not gassing water.

Full bottle of water stored in fridge. Inserted into sodastrem machine, button with 3 lights pressed, see some bubbles in water whilst button held down.

After sodastream finished what its doing the water does not have any bubbles

Try to leave the bottle at the machine for 2 minutes after carbornating then slowly push the lever to get the bottle out.

Mine too!! All lights flashing and have to remove power cable and try to get them to turn off to reset… quite a bit of messing around. Why does this happen and how do I prevent it?? Not a good look for Sodastream to house guests !!

Help! Just got a new refill and I can't finish tightening it without it spraying co2 everywhere! If I leave it loose enough (right before it starts spraying) when I try to carbonate my water it just sprays co2 down the canister instead! I don't understand…

We purchased two gas bottles 5 days ago with 60 L gas cylinders, the screen says we are out of gas, replaced it with a new gas bottle and it is saying the same thing! Any ideas?

Helen Smith - Reply

Installed everything according to directions. but no carbonation taking place. Waste of money in my view. Unit is going back to Costco, I won’t bother getting another one.

Installed cylinder and placed bottles as per simple directions - nothing happened, no carbonation. I don’t feel like messing around with a pressurized gas cylinder to see if there are extra seals as suggested; this thing is a waste of money in my view - it’s going back to Costco and I won’t be getting another one.

How do you screw in the bottle into the SodaStream source? There are no threads to screw the bottle in. Water is leaking out when I try to carbonate it with the bottle.

Alan Joseph J. Caceres - Reply

Same here. I have to « push the bottle up » by placing my fingers under it and pressing up for the carbonation to occur. I can’t screw it, because there’s nothing to screw, but it’s like if it should be, as if it is too loose or something. Hoping for some guidance!

Has anyine figured this out? Having the same issue with the leaking

Armand Avelar -

You don’t screw the bottle in… there’s a chrome U-shaped tab a few inches long behind where the bottle goes… pull it out and the whole assembly will tilt towards you and open up. Put the bottle threads up into the fitting (it will go in now) then push the bottom of the bottle in to tilt everything vertical again. The fitting will grab the threads of the bottle.

Once you figure it out (like I did) you’ll slap your head because it’s so easy.
