Troubleshooting
PROBLEM POSSIBLE CAUSE AND/OR REMEDY
Spotting and filming
No rinse agent:
Does the rinse agent dispenser need to be filled?
Dishwasher detergent:
Use only the correct amount of dishwasher
detergent according to the hardness of the water
and the wash program you have selected. Do not
use old or caked detergent. Store the dishwasher
detergent in a dry place and in a closed container.
Change the dishwasher detergent if the result is
still unsatisfactory.
Items not loaded properly:
Check that you loaded the items according to the
instructions on pages in this manual. Do not
overload. Make sure water can reach all soiled
surfaces.
Dishes are not clean
Check that both wash arms can rotate freely and
that items do not obstruct the movement of the
wash arms. Lift the arms and make sure that no
grains of dirt retard the rotation of the wash arms.
If necessary, clear the obstruction, refit the arms,
and check that they rotate freely. Be sure a utensil
or handle has not prevented their turning.
Strainer blocked Check the strainer. Clean if necessary. Refer to
maintenance section in this manual.
Excessive foam
in the machine Use only dishwasher detergent.
Marks and discoloration Aluminum utensils rubbing against items during
washing:
Be sure aluminum utensils, especially light weight
foil-type pans, do not touch dishes.To remove
spots, use a non-abrasive cleaner.
Small particles deposited
on items Detergent:
Use only fresh detergent. Store in a tightly closed
container in a cool dry place. Fill dispenser only
when ready to start the dishwasher. Use the
recommended amount of detergent, especially
with hard water.
PROBLEM POSSIBLE CAUSE AND/OR REMEDY
Small particles deposited
on items (cont.) Improper loading of dishes:
Load dishes to prevent water and detergent from
being trapped in or between items. Water should
circulate freely.
Flatware incorrectly loaded:
Pay particular attention to spoons so that they do
not nest in each other and prevent water
penetration.
Make sure filters are installed properly.
Filter may have clogged due to heavy sediment,
food soil or hard water conditions.
Yellow or brown marks
Iron or manganese in water:
Temporary solution: Pour in one teaspoon to one
tablespoon of citric acid crystals instead of the
prewash detergent. Follow this prewash with a full
detergent wash. Use the pots/pans or normal
wash cycle.
Permanent solution: Install an iron removal system
in the water supply.
Copper with sterling silver:
Yellow film on sterling silver results when washing
copper items in the same load. Silver polish
usually removes the stain.
Tea or coffee (tannic acid):
Tea or coffee can stain cups. Remove stains by
hand, using a solution of 1/2 cup bleach and 3
cups warm water. (Do not use on sterling silver or
silverplate.)
Discoloration of stainless
steel, silverplate or
sterling silver Allowing salty foods to remain on flatware.
Rinse flatware that is to stand several hours before
washing.
Stainless steel contacting silver:
Do not put stainless steel and silver flatware in the
same silverware basket compartment. Direct
contact between these metals can cause
permanent damage to silver. Clean stained items
with silver polish. Do not use abrasives on
stainless steel or silver.
Distortion of plastics Plastic items have a low heat tolerance:
Plastics vary in their ability to tolerate heat.
Check washing instructions for all plastic items to
be sure they are dishwasher safe.
Marks on melamine and
plastics Porous material:
Use a special cleaner for plastic. DO NOT use
bleach or scouring powder on these materials.
