With the Smeg water soda maker you can manually adjust the desired amount of bubbles using the knob. It is important to remember that the absorption of carbon dioxide by water depends on a few factors: 

• If the water is too hot, it is more difficult for CO2 to bind with water. For best results, it is recommended to use refrigerator water (5°C). 

• As CO2 runs out, less CO2 is gradually added to water. The results therefore vary with a new or almost new cartridge.

Therefore, to obtain a good amount of CO2 in water, we recommend keeping the knob turned for 2-3 seconds or repeating this action several times. For the opposite results, to obtain a less sparkling water, run the carbonation process only once or turn the knob only halfway.

When a hiss is heard, it means that the overpressure safety valve has tripped. Release the knob and return it to the starting position.
