Water hardness

Water hardness is a high concentration of minerals, specifically of calcium, which is responsible for the formation of
limescale. To prevent the scaling of your machine, which may lead to the improper operation or alter the taste of your
coffee, you must set your machine according to the hardness of your water (between 0 and 4).
Prior to the 1st use and in order to set your machine, determine the hardness of your water by using a pH test stick:
- Fill a glass of water
- Immerse the stick
- Wait 1 minute for the result
It is also possible to contact your water company.
You will find detailed information on the classes in the table below:

Be sure to perform this operation at each time you use your machine in a place where the water hardness is
different or if you notice a change in the hardness of your water.
Your machine offers pre-set drinks to obtain optimal results. You may nonetheless personalise your coffee and have an
effect on the results in your cup.
Preparing the grinder: set the grind fineness
You may adjust the strength of your coffee by setting the grind fineness of the coffee beans; the finer the setting of the
coffee grinder, the more the coffee is strong and creamy. The type of coffee used may also influence the result obtained.
We recommend a very fine setting for ristretto, fine for espresso and coarser for lungo.
To set the level of grind fineness:
- Turn the setting knob located in the bean reservoir. This setting must be performed during grinding and notch
by notch.
- After 3 preparations, you will notice a very distinct taste difference.
The variation of grinding fineness allows:
- To be able to adapt to the different types of bean: a highly roasted and rather oily bean will require a coarse
grinding while a more lightly roasted bean will be drier and will require a finer grinding (dark to light bean)
