Determining the water hardness
Water hardness is an indication of the
amount of minerals dissolved in water.
The more minerals in the water, the
higher the water hardness and more
detergent must be dispensed.
Tip: You can measure the water
hardness yourself using the enclosed
test strip. Alternatively, your local water
authority will be able to tell you the
hardness of water in your area.
Dip the test strip in the water for
approx. 1second. Shake excess
water off the test strip.
After approx. 1minute, and based on
the coloration, you will be able to read
the water hardness from the table
below.
