Miele G 890 - Water Softener Settings; Water Hardness Adjustment Table

Water softener
The water softener must be set to corre-
spond to the water hardness in your
area. This can be obtained from your
local water company or by using a test
kit that can be purchased from the
Miele Parts Department.
To avoid the build up of calcium de-
posits on dishes, cutlery, and in the
dishwasher, if the water hardness is
above 7 gr/gal, the water should be
softened.
The dishwasher is factory set for a hard-
ness level of 4 gr/gal. If your water is
harder or softer, the setting will need to
be adjusted.
To ensure a steady supply of soft-
ened water, the built in water sof-
tener must be:
1. Correctly set.
2. Reactivated with salt when depleted.
Where the water hardness fluctuates
(e.g. 8 - 17 gr/gal) always set the ma-
chine to the higher value (17 gr/gal in
this example).
