F) WATER HARDNESS
The hardness of the tap water varies with each region and you should test the hardness of the water you are going to use in your
coffee-maker. Once the coffee-maker has been programmed with the hardness of the water, it will indicate when the lime scale
should be removed from the system.
First, test the hardness of the water. Drop a reagent strip in the water during 1 second. You will see how one box on the strip chang-
es its colour; the hardness will be equal to this colour. Please, check the packaging of this strip to see the hardness of the water.

hardness level of 5.
