Water hardness

Water hardness is a high concentration of minerals, in particular calcium, that is responsible for the formation of
limescale. To avoid scaling of your machine which can lead to the malfunction or alteration of the taste of your coffee,
you must adjust your machine depending on the hardness of your water, between 0 and 4.
Before the 1st use and in order to be able to adjust your machine, determine the hardness of your water using the stick
supplied with your machine: Fig. 2
- Fill a glass of water
- Immerse the stick
- Wait for 1 minute to get the result
- The level of hardness of the water is equal to the number of red areas on the stick. Fig. 3
It is also possible to ask your water company.
