Setting the water softener

To avoid the build-up of calcium de-
posits on crockery and in the dish-
washer the water needs to be softened,
if it is harder than 107 ppm.
To ensure a steady supply of soft water
the water softener unit must be:
– correctly set, and
– the salt reservoir in the floor of the
wash cabinet must be topped up
with dishwasher reactivating salt
as soon as the k light comes on.
The water softener must always be set
to correspond with the water hardness
the first time the machine is used.
Your local water authority will advise
you on the water hardness in your area.
Setting the water softener
The hardness range is divided into 18
time settings and a zero position. The
dishwasher is set at the factory for a
water hardness setting "8", correspond-
ing to 339 ppm.
If your water supply is harder or softer
than this, then:
Use the touchpads on the control
panel to change the setting, (see
table).
