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.
Cause 1: 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.
Cause 2: 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.
Cause 3: 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.

Another option is to just return it. That is what I am doing, because mine did not last 8 months

My soda stream source model is leaking gas through the actual On/Off Valve and a small amount of CO2 is coming out of the injector when it’s off. I believe it is due to debris/sheddings from the nylon threaded valve housing(subassembly) that accepts the bottle. I have disassembled the entire unit and discovered nylon threaded shavings around this contact area. and the seal up inside where the bottle makes its contact. This is the entire On/Off valve assembly for the unit. I need to try to find O-rings for this subassembly. I also noticed that the CO2 injector nozzle was letting out LESS gas than usual, on a full bottle. So I also believe debris made its way into the nozzle itself. I have attempted to blow that potential clog out. But I still have this small leaking valve issue. It could be a damaged O-ring in the valve. Does anyone know where to get the actual On/Off valve O-rings and seals for this subassembly? I'll assume, probably not. I will try to find exact fit/sized O-rings from industrial suppliers.

Turns out it was actually my bottle valve itself that was leaking. The plunger in the bottle wasn’t re-seating itself perfectly back in to seal the gas and was leaking out ever so slightly. Everyone might want to check that once and a while by doing either a bubble test on the bottle itself or a bubble test on the injector nozzle on a regular basis. That’s what I’m going to be doing from now on. The slightest amount of debris, metal, dirt, or nylon in any of the valve seats of this device will cause leakage. I can’t believe they made all the valves/bodies/housings out of nylon/plastics. Metal/aluminum (the bottle) does not play well with plastic threads.

“. If the SodaStream Source does not detect the carbonation bottle, the system will not activate or respond. “ Do you mean the CO2 bottle/cylinder? I kind of also think you mean the bottle that holds the water (to be carbonated) You can still make the SodaStream discharge CO2, even without the carbonation water bottle attached. I guess you mean if the gasket seal/washer up in the threaded housing (on the back) where the “CO2 cylinder” attaches, is more than just the one gasket that there is supposed to be, then, the CO2 cylinder valve plunger is too far away from the activation pin in said housing, and won’t make contact with said CO2 cylinder valve-plunger/seal, causing no gas to be released.
