How do I get my SodaStream DUO™ Sparkling Water Maker to stop leaking water?

Make sure you are filling the Glass Carafe / BPA Free carbonating bottle with water to the fill line only (0.84L).

The SodaStream DUO™ Sparkling Water Maker can be used with our dishwasher-safe 1L glass bottle and our regular 1L Fuse bottle. The 1L classic bottle, the 0.7L glass bottle (from the SodaStream Crystal™), the 0.5L bottle and My Only Bottle (0.5L) are not compatible.

Check the following compatibility chart:

Try reinserting your bottle and push the carbonating head down. Make sure the bottle flask is properly locked with the carbonating head and the carbonating tube is inside the bottle. Hold the carbonating head down and turn the flask lever left to the locked position to ensure safety.

Carbonate water only. Flavours should only be added after carbonation.

To carbonate, push the carbonating button down firmly for ~2 seconds, release, and repeat. Repeat 3 times for light fizz, 5 times for strong fizz, and more for extra strong fizz.
