Water hardness
In order to achieve good dishwashing results, the dishwasher needs soft water (water with low mineral
content). Hard water leaves a white coating on dishes and the dishwasher.
Checking water hardness
Water hardness is specified using German degrees of water hardness (°dH), French degrees of
water hardness (°fH), English degrees of water hardness (°eH), millimoles per liter (mmol/l), or grains
per gallon (gr/gal).
A water supply with a water hardness in excess of 5°dH (9°fH / 6°eH / 0.9 mmol/l / 5.9 gr/gal) must
be softened. This is done automatically with the aid of the built-in water softener. In order for the
water softener to function properly, its settings must be adjusted to the hardness of the water supply.
Once you have adjusted the water softener settings, add detergent and rinse aid in doses suitable
for soft water.
Contact the local water utility to check the water hardness in your area.
Make a note of the water hardness:____________

If the water hardness exceeds 50°dH (89°fH / 62°eH / 8.9 mmol/l / 52.0 gr/gal), we recommend
connecting an external water softener.
WARNING!
Hard water leaves a white coating on dishes and inside the dishwasher. It is therefore important
that you select the right setting for the water softener. See Water hardness.
Never run the dishwasher with an empty salt compartment if the water supply has a water hardness
in excess of 5°dH (9°fH / 6°eH / 0.9 mmol/l / 5.9 gr/gal).
