switch to 3rd level.

If the hardness level of the supply water is above 90 °dF or if you are using well water, then it is
recommended to use water purification devices and special filters.
If the hardness level of the supply water is below 13°dF, there is no need to use salt in your dishwasher.
If this is the case, "No Salt Warning Indicator" (if any) illuminates continuously on the panel of your
machine.
If the water hardness level adjustment is set to level 1, the "No salt warning 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 Salt indicator will not illuminate.
