Gas will not stop escaping after carbonation

If you are hearing a hissing noise coming from your SodaStream Source, the carbonation tube is leaking gas, or the carbonation bottle is leaking, use the SodaStream Source is Leaking Gas problem page to fix the leak.

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. 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 no longer leak.

If your SodaStream Source is leaking during carbonation, see the SodaStream Source is Leaking During Carbonation problem page instead.
