8. The method for operating a water dispenser according to claim 1 , wherein the controller provides signals based on the determined volume ratio (R) and/or the determined nominal value of the waiting period (WP) to other components of the water dispenser.

9. The method for operating a water dispenser according to claim 1 , wherein the water volume (V), the nominal value of the waiting period (WP) and/or the volume ratio (R) is determined by gathering information from a computer-readable medium of the water dispenser.

10. The method for operating a water dispenser according to claim 1 , wherein the water volume (V), the nominal value of the waiting period (WP) and/or the volume ratio (R) is determined by identifying which button of a multitude of buttons is pressed on the user interface and then gathering information from the computer-readable medium based on the identification of the button pressed by the user.

11. The method for operating a water dispenser according to claim 1 , wherein the method further comprises the step of providing information about a status of the method to the user.

12. The method for operating a water dispenser according to claim 1 , wherein the saturation degree (D) of carbon dioxide is varied based upon selection using the user interface.

13. A computer-readable medium having stored thereon a computer program comprising instructions to cause a water dispenser having a water supply, a carbon dioxide supply, an outlet for pouring water into a container placed below the outlet, a controller and a user interface to execute the steps of the method of claim 1 .

14. A water dispenser having a water supply, a carbon dioxide supply, an outlet for pouring water into a container placed below the outlet, a controller, a user interface and the computer-readable medium according to claim 11 .

15. The water dispenser according to claim 14 , wherein the water supply comprises a water tank and/or a coupling for connecting the water dispenser to an external water supply system.

16. The water dispenser according to claim 14 , wherein the carbon dioxide supply comprises a carbon dioxide tank and/or a coupling for connecting the water dispenser to an external carbon dioxide supply system.
