FILLING WITH SALT
+, Your machine is fitted with a water softening
Vi filter. The softening process prevents limescale
deposits forming in the machine and on your dishes.
Before using the machine you must fill the special
container at the bottom of the machine with coarse
salt available especially for dishwashers. Do not use
table salt. The container holds 1.5 kg of salt, which
is sufficient for 15-30 loads, depending on the
amount dispensed (see below).
Es Unscrew the lid of the salt container (inside the
=> machine, at the bottom to the right of centre,
marked with the symbol shown here). Use the funnel
supplied to fill the container first with ordinary water
and then with coarse salt. Remove the funnel and
wipe away any spilt salt. (Spilt salt which is not
cleaned up is corrosive and can cause spots on the
stainless steel surfaces of the machine.) Screw the lid
back on and run a rinse programme if you are not
going to wash straight away.
NEVER OPERATE THE MACHINE WITH AN EMPTY SALT CONTAINER
If you do, there is a serious risk of damaging
the water-softening function. (If the damage is
slight, the function can be partly restored by
running the short programme 4-5 times after
refilling with salt.)
A small light on the front panel indicates when
the salt needs topping up.
AMOUNT OF SALT DISPENSED
Water-softening requires varying amounts of salt
depending the hardness of the water. The amount of
salt dispensed is set using the small red selector screw
at the top right-hand corner of the machine. The
selector can be set in two positions (use a screwdriver
or similar tool): l
* Position 1 for water softer than 20 °dH.
* Position 2 for water of 20 °dH or more.
If you do not know how hard your water is, you can
start with position 1 and then move to position 2 if
limescale deposits appear in the machine. If lime
deposits do develop, they can be removed by filling
the detergent dispenser with approx. 60 grams of citric
acid and running a long programme with the machine
empty.
