Are you hearing a hissing noise coming from your SodaStream Source? Is the carbonation tube leaking gas when the machine is not in use? Is your carbonation bottle leaking? Will gas not stop escaping after carbonation is complete? SodaStream Sources are susceptible to a range of problems that could cause them to leak gas, most of which are simple to fix. Check the following possible causes to identify and solve the problem.
If your SodaStream Source is leaking during carbonation, see the SodaStream Source is Leaking During Carbonation problem page instead.
Carbonation Canister is Loose
If the SodaStream Source’s carbonation canister is not firmly set, you may hear gas (carbon dioxide) leaving the carbonation bottle or the carbonation tube. Leaking gas can be caused by having a worn-out sealer washer or having too many sealer washers in place. This problem can also occur if the carbonation bottle is not screwed in all the way. Make sure that the carbonation bottle is securely fastened before using the machine.
- 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.
Too Many Sealer Washers
If there are too many sealer washers present in the carbonation attachment area, the SodaStream’s carbonation bottle will not be able to hold in place. If the SodaStream Source does not detect the carbonation bottle, the system will not activate or respond. Check your SodaStream’s carbonation attachment area with tweezers. Pull out the small black rubber ring from the carbonation attachment area and see if there is a second rubber ring present underneath the first one. If there is a second ring, leave that one in place and keep the extra rubber ring for future use.
Washer Needs to be Replaced
If the SodaStream Source’s sealer washer becomes worn out in the carbonation attachment area, the SodaStream’s carbonation bottle will shift or not hold firm when attached. If the SodaStream Source does not detect the carbonation bottle because it is not inserted properly, it will not respond to the user’s commands. To remove and replace the sealer washer, use a pair of tweezers to pull the small black rubber ring out of the area where the carbonation bottle attaches to the SodaStream. Replace the old sealer washer with a new washer and try to reattach the carbonation bottle. If the carbonation bottle is attached firmly, the SodaStream Source should respond.
Gas Tube is Loose
The SodaStream Source includes a two-inch long white gas tube located in the connection area. This tube, which goes inside of the carbonation bottle, can become loose on some models. You will feel the carbon dioxide gas escaping as you press the lever on the top of the machine to dispense the gas. Tighten the white tube’s connection points so that no air can escape, and try again.
Internal Carbonation Air Hose Needs to be Replaced
The SodaStream Source has a pressure relief valve, and it is normal for some gas to come out of this valve. Try to find the location of the leaking gas by checking the carbonation bottle and the carbonation hose.
If you have tried the previous solutions and are still hearing gas leaking from the carbonation tube, use this SodaStream Source Internal Carbonation Air Hose Replacement Guide to replace the device’s internal carbonation air hose. This solution requires taking apart the SodaStream Source.
