Setting up the water softener
Important!
Only some models (DD24-H and DD60-H) have a built-in water softener.
Models with water softener are not currently available in New Zealand and Australia.
Determine the water hardness in your local area
Your local water company will be able to provide you with information. Identify the setting you
require for your DishDrawer® from the water hardness table below. For example, if your water
hardness is 500ppm, then the water softener setting on your DishDrawer® should be 4. Refer to
the ‘Option adjustments’ section to adjust the water softener so that the setting corresponds to
your water hardness.
