The new function makes life in the kitchen even easier. It saves you time and space, it means you no longer need to use plastic bottles and it is completely safe. To dispense sparkling water, press and turn at the same time. The illuminated ring that turns red to indicate boiling water now flashes blue: sparkling water comes out of the tap. And if you hold down the button for slightly longer and then turn it, you get filtered water. So it’s impossible to dispense boiling water when you want sparkling water.
