If the hardness level of the water that you use is above 90°dF (French standard for water
hardness) or if you are using well water, than it is recommended to use filter and water
purification devices.
* If the hardness level of the water that you use is below 8°dF (French standard for
water hardness), there is no need to use salt in your dishwasher. If this is the case, Salt
Indicator (if any) illuminates continuously on the panel of your machine.
If the water hardness is set to level 1, the Salt Indicator will illuminate continuously
although it is not necessary to use salt. If you use salt under this condition, salt will not
be consumed and the lamp will not illuminate.
