Soft water situations
If you live in an area of naturally
soft water or your household water
is softened, avoid using too much
detergent in your DishDrawer®. An
excess amount of detergent is very
aggressive on glassware and may cause
irreversible etching.
Etching is a chemical deterioration
that occurs on the surface of
glassware when it is subjected to high
temperatures, too much detergent
and/or soft water situations. Etching
is caused by a combination of very hot
water, which causes the detergent to
become very aggressive, but because
the water is soft, there are no water
hardness mineral ions for the detergent
to bind to, so it extracts mineral ions
directly from the glass.
Etching looks like rainbow colored
film, as the glass is subjected to further
washing the surface will eventually
appear opaque. This type of etching is
irreversible.
To prevent further etching from
occurring on glassware use less
detergent (follow the recommended
detergent quantities in the Use & Care
for soft water situations), and ensure
the dishwasher is not overloaded, so
water can reach all the dishes during
the wash.
Hard water situations
If you live in a hard water situation,
we recommend the installation
of a household water softener to
improve the water quality, detergent
effectiveness and prevent the build up
of calcium deposits on dishes and in
the DishDrawer®.
Certain brands of dishwasher
detergent contain varying quantities of
phosphates, which help soften water.
We suggest you use a detergent with
high phosphate content to improve the
wash. The detergent compartments
need to be completely FULL and rinse
agent is used with its setting fixed at 5.
We recommend the use of a dishwasher
cleaner/descaler whenever you notice
a build up of calcium deposits in your
DishDrawer®.
After you have used the dishwasher
cleaner/descaler you must run another
wash program with detergent to
prevent damage to the DishDrawer®.
