Inappropriate amount of dishwasher detergent for
the degree of water hardness or the amount of food
â€¢ The general recommendation is one teaspoon of detergent
for each grain of water hardness (gpg), with a minimum
of three teaspoons when water is soft.
Refer to the following chart:
Water Hardness Detergent Use
Soft (0-3 grains) 3 tsp.
Medium (4-9 grains) 4-9 tsp.
Hard (10-13 grains) 10-12 tsp.
Very Hard (14G grains)
To determine water hardness:
a. Use a Water Hardness Test Kit
(Maytag Part No.038184).
b. Contact the local water utility or state university
â€¢ For normal or longer cycles, place the prescribed
amount of detergent in each of the cups.
â€¢ When choosing a light wash or shorter cycle, place the
prescribed amount of detergent in the main wash cup
3. Improper loading.
â€¢ All items should be loaded so they are separated and
facing the center.
â€¢ Large bowls or pans should not be placed over the center
of the lower rack where they could block the wash
action of the center spray tower.
â€¢ Larger items should not be placed so that they shield
smaller items from the wash action.
â€¢ Bowls should not be nested together as water is then
unable to reach all of the surfaces.
â€¢ Spoons and other silverware should be loaded with
some handles up and some down to prevent nesting.
â€¢ Avoid loading items in a manner that would restrict the
rotation of the spray arms.
â€¢ Avoid loading large objects in a position that would
block the detergent dispenser from opening.
4. Improper water fill.
If the water level is low:
â€¢ Check to be sure that there are not other hot water
activities (such as laundering or showers) occurring at
the same time the dishwasher is running.
â€¢ Check that the dishwasher is level from front to back
and side to side.
â€¢ Check for an immobilized float.
â€¢ Check for low water pressure.
5. Use of old or caked dishwasher detergent.
â€¢ Detergent should be fresh and stored in a cool, dry
â€¢ Detergents should NOT be stored under the kitchen
â€¢ Detergents should not be stored for extended periods of
time prior to useUse of too much dishwasher detergent (especially
liquids and gels) for individual water conditions.
Iron or manganese in the water supply can cause
brown, red or black stains on dishes or the dishwasher
â€¢ To remove this type of discoloration on dishware and
the dishwasher tub, use a rust remover such as RoVer*
Rust Remover (Part No. 057961). Do Not use RoVer
with metal items.
a. Fill both detergent cups with RoVer.
b. Set the controls and run a normal wash cycle.
c. Follow with an additional rinse cycle.
d. DO NOT use RoVer with dishwashing detergent.
A lime film or deposit may eventually build up on the
dishwasher interior if there is a high calcium level in
the water supply.
â€¢ Try ONE of the following procedures to remove this
type of deposit:
a. Use a damp cloth and a mild scouring powder.
b. Initiate the Rinse & Hold portion of a cycle (with an
empty dishwasher). During the fill, open the door
and add 1/2 cup white vinegar to the water. Allow the
cycle to complete (without detergent). Follow with a
Normal cycle with detergent.
c. Fill both detergent cups with RoVer* Rust Remover
(Part No. 057961). Set the controls to complete the
Normal wash and rinse cycles. Follow with a shorter
wash cycle with detergent. Do not use RoVer in the
cycle with dishwasher detergent.
1. Dishes washed too infrequently.
â€¢ Run a Rinse & Hold cycle, if dishes are being held until
there is a full load, to prevent food soils from causing
