Soft water is required for dishwashing to prevent the build up of scale (lime deposits) on your dishes and
in your DishDrawer®. If hard water is used for dishwashing, you will notice glasses will become opaque,
dishes will become spotted or have a white film on them and your dishwasher will become less efficient
over a period of time. Tap water above 100ppm must be softened for dishwashing for optimum wash
performance.
The DishDrawer® is fitted with a water softener which is designed to remove the calcium and magnesium
ions that cause water to be ‘hard’. The water softener will automatically remove the hardness from
the water using a salt solution. The amount of salt required will depend on the local water hardness. Your
local water company will be able to provide you with the information on the water hardness in your local
area.
To Ensure Optimum Performance of the Water Softener
The water softener must be set to the correct local water hardness and must always be filled with granular
salt made especially for dishwasher water softening systems. We do not recommend the use of cooking
salt like table or rock salt or pellets as they may contain impurities that will impair or diminish the life of
the water softener.
SETTING UP THE WATER SOFTENER
Determine the Water Hardness in Your Local Area
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 the Option Adjustment Mode to adjust the water softener so that the setting corresponds to your
water hardness.
DishDrawer®
setting °dH °fH °e 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
NOTE
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 be at 5. If your water hardness is
above 625ppm, the performance of your DishDrawer® will decline.
