Before Using your Appliance...
ADJUSTING THE WATER SOFTENER...
In order to rinse dishes and glasses
satisfactorily, the dishwasher requires
soft water i.e containing little or no
lime, otherwise water stains are left
behind on crockery and glasses etc.
If the tap water exceeds a certain
level of hardness, it must be
softened, ie. decalcified, so that it
can be used in the dishwasher.
The water Softener should be
properly adjusted to optimise salt
consumption and for best washing
results.
In order to ensure that the correct
amount of salt is being used to
regenerate the water softener, the
water hardness adjuster needs to be
set accordingly. To set this correctly
the hardness of your water needs to
be ascertained. Find on the table the
level corresponding to the hardness
of your water and the required
adjustments or contact your local
Water company to find the exact
water hardness level for your area.
