Setting up the water softener
Important!
Only GB IE models have a built-in water softener.
Models with water softener are not currently available in New Zealand, Australia, USA or Canada.
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.

Notes:
If your water hardness is above 625ppm, we highly
recommend you completely fill the appropriate
compartment(s) of the detergent dispenser for all
programmes except Rinse and the rinse aid setting
should be at 5. If your water hardness is above
625ppm, the wash performance of your DishDrawer®
will decline.
You may hear some unusual noises when the water
softener is in operation, this is normal.
How to fill the salt reservoir
1
Open the DishDrawer®.
2
Unscrew the salt reservoir cap by turning anticlockwise.
3
Place the salt into the salt container and pour the contents into the salt reservoir. The salt
reservoir can hold up to approximately 1 lb/0.5 kg of salt.
4
Fit the cap tightly back into its original position.
5
If you do not wash your dishes immediately after filling the salt reservoir, run a Rinse programme
to remove any salt water or spilt granules.
Note:
When filling the salt reservoir, you may notice water being displaced from the water softener
overflow.
