The water softener produces a salt solution to soften the water in regions with hard water.
It maintains good wash performance and prevents scale buildup. You do not need to use
this feature if you have a household water softener installed.
Salt recommendations
The salt reservoir must always be filled with granular salt designed for dishwasher water
softening. We do not recommend the use of cooking salt like table salt, rock salt or pellets
as they may contain impurities that will damage the water softener. Do not add detergent
or rinse aid to the salt reservoir. This will cause damage.

Water hardness recommendations
Use the table below to determine the optimal water hardness setting. Your local water
z
company will be able to help.
If you have a household water softener installed, use the setting recommended for water
z
with a hardness under 100 ppm/6 gpg, irrespective of the water hardness in your area.
If your water hardness is above 625 ppm/36 gpg, the wash performance of your
z
DishDrawer™ Dishwasher will decline over time. The rinse aid setting should be at 5.
