HARD WATER FILMING
POSSIBLE CAUSES:
♦
Hard water and not using enough
dishwasher detergent may leave hard
water minerals which dry on the
surface of glassware creating a film.
Un-removed food soil may also cause
filming. Increase the amount of
detergent according to the degree of
water hardness (one teaspoon per
grain). See page 17 for a chart with
the amount of dishwasher detergent
according to water hardness. For water
hardness over 12 grains, add additional
detergent (1 teaspoon for each grain
over 12) at the beginning of the main
wash portion of the cycle. (Open door,
add detergent to bottom of tub, close
door and dishwasher will continue
through cycle). Certain water
conditions, such as extreme hardness,
may make it virtually impossible to
use a dishwasher. Water softeners are
available to improve water quality.
♦
Low water temperature.
Adjust the water temperature so that it
enters the dishwasher at 140° F. Use a
water heating option, if available.
♦
Not using a rinse aid. Use a rinse aid,
such as Jet Dry according to the
dishwasher’s User’s Guide.
TO REMOVE:
Wash dishes in the dishwasher
using glass Magic according to
package directions. If filming is
extremely bad, it may be necessary to
repeat the procedure.
ETCHING:
The permanent film known as
etching occurs in unusual
circumstances where the surface of
glass is pitted or eroded. In the
beginning stages etching may be
identified by an iridescent look – shade
of blue. Purple, brown or pink may be
seen when the glass is held at an angle
to the light. In advanced stages the
glassware appears frosted or cloudy.
Certain types of glass will etch in any
dishwasher with the combination of
soft water (especially mechanically
softened), the alkalinity of dishwasher
detergents and heat. There is not way
to remove etching, the damage is
permanent. Neither is there any way
to predict what glassware may be
affected. It is not related to the cost or
quality of the glass.
TO PREVENT RECURRENCE:
♦
Adjust the amount of detergent
according to water hardness. (One
tablespoon per wash cycle is the
minimum amount of detergent
recommended.) See page 17 for a
chart with the recommended amount of
dishwasher detergent according to
water hardness.
♦
Lower water temperature so that it
enters the dishwasher at approximately
140°F. Do not use water heating
options.
♦
Use the Air Dry option.
♦ Do not manually pre-rinse dishes
before loading in dishwasher.
Removing all the food soil prior to
loading simply increases the
possibility of etching.
WATER SPOTTING AND RACK MARKS
Spots are caused by dissolved salts and
minerals remaining on glasses and
flatware after the water evaporates.
This usually happens in hard water, but
can also happen in mechanically
softened water.
POSSIBLE CAUSES:
♦ Not enough dishwasher detergent.
Increase the amount of dishwasher
detergent according to water hardness.
