Water softener
Setting up the water softener
Using hard water (above 100ppm) for dishwashing can be detrimental to the performance of
your DishDrawer®. Glasses will become opaque and dishes will become spotted or covered in a
white film.
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 four. Refer
to Option Adjustments section to adjust the water softener so that the setting corresponds to
your water hardness.
DishDrawer®
setting o dH o fH o e / o Clark mmol/l ppm
0 0 - 5.6 0 - 10 0 - 7 0 - 0.1 0 - 100
1 5.6 - 14 10 - 25 7 - 17.5 0.1 - 2.5 100 - 250
2 14 - 19.6 25 - 35 17.5 - 24.5 2.5 - 3.5 250 - 350
3 19.6 - 25.2 35 - 45 24.5 - 31.5 3.5 - 4.5 350 - 450
4 25.2 - 30.8 45 - 55 31.5 - 38.5 4.5 - 5.5 450 - 550
5 30.8 - 35 55 - 62 38.5 - 43.8 5.5 - 6.2 550 - 625
Notes:
If your water hardness is above 625ppm, we highly recommend you completely fill the detergent
compartment for all programmes except Rinse and the rinse aid setting should be at 5. If your
water hardness is above 625ppm, the 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 plug 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 0.5kg 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 dispenser, you may notice water being displaced from the water
softener overflow.
