DISHWASHER
POOR CLEANING
Q: I recently purchased a new dishwasher and
have noticed that food soil is occasionally left
on some dishes at the end of the cycle. What
could be causing this?
A: When poor cleaning occurs, it is usually related
to water conditions, detergent usage andlor loading
conditions. To achieve optimum results, we suggest
reviewing the following:
Temperature
Proper water temperature is needed to activate the
dishwasher detergent, dissolve greasy food soils
and warm the interior for good drying results.
'%
,
The water heater should be set at 140°F. if water
heating options on your dishwasher are not
available or not selected. If water heating options
are used, the water heater may be set to deliver a
minimum of 120°F water to the dishwasher.
To check the water temperature, place a
thermometer in a glass and set it in the sink below
the faucet, allow hot water to run into the glass until
the temperature stabilizes and take a reading.
To ensure that the dishwasher is filling with the
hottest water possible, do the following:
Before starting the dishwasher, let the faucet at
the nearest sink run until the water is hot.
Avoid running the dishwasher while hot water is
being used for other activities like showers.
Detergent
.."
The amount of detergent used depends on the
water hardness and amount of ,soil on the dishes.
When very soiled or greasy pans are washed, extra
detergent will be needed. In addition, if the
detergent is caked or clumped from absorbing
moisture, it may not dissolve and activate properly.
Purchase fresh detergent and store it in a dry place
(not under the kitchen sink).
FORM NO.728CG-0996
As a general guide, use one teaspoon of detergent
for each grain of water hardness, with a minimum of
three teaspoons in soft water. However, when using
a concentrated dishwashing detergent, decrease
the amount by half.
For example, if the water is 10 grains per gallon
hard use 10 teaspoons of detergent. For a normal
or longer cycle place 10 teaspoons of detergent in
each detergent cup. For shorter cycles place the 10
teaspoons of detergent in the MAIN WASH cup.
Soft (0-3 grains) .................................. 3 Teaspoons
(fill to the first line)
Medium (4-9 grains) ........................ 4-9 Teaspoons
(fill to the second or third line)
Hard (10-12 grains) .......................10-12 Teaspoons
(fill to the third line or above)
If the water is over 15 grains, a mechanical water
softener may be the only permanent solution. Do
not use packaged water softeners such as Calgon
or Spring Rain*. They create excessive suds.
Cycle Selection
The proper cycle needed depends on the amount of
food soil. Selecting a short cycle will save water
and energy. However, it may not provide adequate
cleaning for heavily soiled dishes. If foods remain
on dishes, a longer cycle may be required. Check
the User's Guide for cycle recommendations.
Loading
For specific placement of dishes, glasses and
flatware, refer to the User's Guide. However, here
are some loading guidelines:
As a general rule, place all items in the racks so
they are separated and face the center of the
dishwasher to ensure the water spray will reach
the soiled surfaces.
. . . more
Printed in U.S.A.
Make sure the movement of the upper and
lower spray arms are not blocked by items
extending above or below the racks.
Place glasses in any row of the racks for proper
cleaning and rinsing. Do NOT load glasses
over the tines.
The center wash tower provides wash action for
the middle of the dishwasher. Avoid placing
large items over the wash tower.
Carefully load the dishwasher by placing only
one item between each set of tines.
Load the dishwasher so large items do not
shield small items from the washing action.
If flatware i s nested, water cannot reach all
surfaces. Load flatware with some handles up
and some down to prevent nesting.

ETCHING
Q: I've noticed that my glasses are turning a
blue-purple color. Why is this happening and
what can I do?
A: The color change to blue, purple, pink or brown
is an indication that etching has begun. This is a
permanent film that occurs in unusual
circumstances and causes glassware to pit or
erode. In advanced stages, the glasses will appear
frosted, spotted or cloudy.
TO PREVENT
1. Since etching usually happens in soft water (0-3
grains), adjust the amount of detergent to match
the hardness of the water. Your local water
utility or a water quality company such as
Culligan or Kinetico can tell you the water
hardness for your area.
As a general rule, one teaspoon of detergent is
needed per grain of water hardness with a
minimum of three teaspoons. However, when
using a concentrated dishwashing detergent,
decrease this amount by half.
TO IDENTIFY
To verify that the film is etching, soak the glass
approximately 5 minutes in undiluted white vinegar.
Rinse and dry. If the film is not removed, it is
etching. If the film is removed, it is possibly hard
water filming. (See Form No. 727CG.)
CAUSES
For a normal cycle place the recommended
amount of detergent in each detergent cup. For
shorter cycles place the recommended amount
of detergent in the MAIN WASH cup only.
2.
Lower the water temperature so that it enters
the dishwasher at approximately 130°-1400F.
Check the water temperature by placing a food
thermometer in a glass and letting it fill with
water from the hot water faucet. Let the water
run until the temperature stops rising. If it is
over 140°F, lower the water heater setting.
3.
Use water heating options on your dishwasher
when incoming hot water is 120°F or lower.
Certain types of glassware will etch in any
dishwasher with the combination of:
soft water (0-3 grains per gallon)
excessive detergent
excessive water temperature
prerinsing of items
There is no way to predict what glassware may be
affected by etching as there is no relationship to the
cost or quality of the glass.
4. Do not manually prerinse dishes before
loading in the dishwasher.
This will
aggravate etching.
TO REMOVE
There is no way to remove the filmy appearance
caused by etching the damage is permanent.
However,
by
following
the
previous
recommendations, future damage may be
prevented.

HARD WATER FILMING
.Q: I have a white film on my dishwasher tub and
glasses. Why is this happening? What can Ido?
For a normal or longer cycle place the
recommended amount of detergent in each
detergent cup. For shorter cycles place the
recommended amount of detergent in the MAIN
WASH cup only.
A: The white film occurs when hardness minerals
from the water are deposited on the glasses and tub.
This is a film that normally occurs when the water is
hard, not enough detergent is used, water
temperature is low or no rinse aid is used.
If the water is over 12 grains hard, you may need
to use additional detergent (1 teaspoon for each
grain over 12) at the beginning of the main wash
portion of the cycle. (Open the door, add
detergent to the bottom of the tub, close the door
and the dishwasher will continue through the
cycle.) If this does not give satisfactory results,
the only solution may be to soften the water
mechanically. When water is over 15 grains of
hardness, it is very difficult to get good
dishwashing results in any brand of dishwasher.
TO IDENTIFY
On glasses:
To verify that the white film is hard water filming,
soak the glass approximately 5 minutes in undiluted
white vinegar. Rinse and dry. If the film is removed
it is hard water filming.
If the film is not removed, it is possibly another type
of film such as etching. (See Form No. 726CG)
Results may improve by switching to a different
type or brand of dishwasher detergent.
9 On tub:
Saturate a cloth with white vinegar and wipe the tub.
If the film is removed, it is hard water filming.
POSSIBLE CAUSES
1. Hard Water And Not Enough Detergent
This combination may leave hard water minerals
on glassware and the tub creating a film.
To prevent, increase the amount of detergent
used according to the degree of water hardness.
As a general rule, one teaspoon of detergent is
needed per grain of water hardness with a
minimum of three teaspoons. However, when
using a concentrated dishwashing detergent,
decrease the amount by half. Your local water
utility or a water quality company such as
Culligan or Kinetico can tell you the water
hardness for your area.
Soft (0-3 grains) ...........................3 Teaspoons
(fill to the first line)
Medium (4-9 grains) .................4-9 Teaspoons
(fill to the second line or third line)
Hard (10-12 grains) ...............10-12 Teaspoons
(fill to the third line or above)

Low Water Temperature
Proper water temperature is needed to activate
the dishwasher detergent, dissolve greasy food
soils and warm the interior for good drying
results.
The water heater should be set at 140°F. if
water heating options on your dishwasher are
not available or not selected. If water heating
options are used, the water heater may be set to

DISHWASHER POOR DRYING
To check the water temperature, first place a
thermometer in a glass. Next, position this
glass under the faucet in the sink nearest the
dishwasher and run hot water into the glass.
Once the temperature stabilizes, read the
temperature from the thermometer.
Q: How can I get the best drying results in my
dishwasher?
A: Good drying results depend on several factors appropriate cycles, options, and usage must be
considered.
To ensure the dishwasher is filling with the
hottest water possible, do the following:
Some items are difficult to dry even when all
recommendations are followed. Cups and glasses
with concave bottoms will hold water at the end of
the cycle. Plastic and Teflon* items have a porous
surface which holds water droplets. Towel drying of
these items may be necessary.
Before starting the dishwasher, let the faucet
at the nearest sink run until the water is hot.
Avoid running the dishwasher while hot
water is being used for other activities like
showers or laundry.
For best results we recommend:
1. Use Rinse Aid
A rinse aid such as Jet-Dry or Cascade Rinse
Aid* greatly improves drying results and
prevents water spotting.
Rinse aid is a
nontoxic, water surfactant which makes water
slide off the dishes more easily.
For
dishwashers with an automatic rinse aid
dispenser (located in the door), use a liquid
rinse aid. For models without a dispenser, hang
a rinse aid basket or disc in the back right
comer of the lower rack.
Costs per cycle of liquid rinse aid vary between
2-6 cents on adjustable rinse aid dispensers.
On nonadjustable dispensers the cost is about
6 cents per cycle.

Load Properly
Face soiled sufaces to the center.
Keep large items from shielding small items.
Use Heat Dry
When heat is added to the dry portion of the
cycle, the
heating element operates
intermittently to greatly improve drying results.
The difference in energy use between heat dry
and air dry equals about $3.00 per year based
on washing six loads per week.
Use Hot Water
Hot water is essential to achieving proper drying
results. The water heater should be set at
140°F. if water heating options on your
dishwasher are not available or not selected. If
water heating options are used, the water
heater may be set to deliver a minimum of
120°F water to the dishwasher.
Use the Proper Amount of Dishwashing
Detergent
Dishwasher detergents contain ingredients that
improve the sheeting action of the water and
aid in drying performance. The amount of
detergent depends on the water hardness and
degree of food soil. A general recommendation
is to use one teaspoon of detergent for each
grain of water hardness, with a minimum of
three teaspoons. When using a concentrated
detergent, decrease this amount by half.
Load only .one item between each set of
tines.
Avoid placing glasses over tines. This
interferes with cleaning and drying results.
Place silverware in the basket with some
handles up and some down.
Check the User's Guide for more loading
recommendations.
