TROUBLESHOOTING
If you should experience a problem with your dishwasher,
you should review the list of frequently encountered
situations below. It could save you the cost and
inconvenience of a service call.
Even though the product is under warranty, if the problem
is not caused by defective product workmanship or
materials, you will be charged for a service call. Refer to
page 17 to determine what is and is not covered under
your warranty. If you’re still not sure, contact the ASKO
Advisory Center before you call a service technician.
BEFORE YOU CALL
Before calling for service or contacting ASKO regarding
a warranty issue, make a note of the model name, type
number and serial number. The model is on the front of
the dishwasher. The type plate with the type name and
serial number is located on the inside edge of the door.

To remove hard water spots, try the following:
1. Run dishes through a normal wash program.
2. Remove all metal dishware, such as cutlery, pans,
etc., from the dishwasher.
3. Do not add detergent. Instead, pour two cups of
vinegar into a bowl and set the bowl face up on the
REMOVING HARD WATER SPOTS FROM DISHES
bottom rack of the dishwasher.
4. Run the dishes through a Normal wash program.
If this doesn’t work, try the same process with 1/4 cup of
citric acid crystals (available at most drug stores) instead
of vinegar.
Stains and discolorations
Stains or discoloration on dishes could be caused by a
number of things. Listed below are some of the most
common causes. See also “Washing Special Items” on
page 15.
♦ Too much iron or manganese in the water can cause
yellow or brown marks on your dishes. As a
temporary solution, in place of the prewash detergent,
use one teaspoon to one tablespoon of citric acid
crystals. You should consider installing a water
filtering system.
♦ Coffee and tea stains usually have to be removed by
handwashing in a solution of 1/2 cup bleach and one
quart of water. (Do not use on sterling silver or silver
plate.) Be sure to rinse these items thoroughly before
putting them in the dishwasher so there is no bleach
residue on the dishware.
Etching
If you have a cloudy film on your dishes that can’t be
removed, it could be etching. To prevent etching, try the
following:
♦ Use less detergent. You may be using too much for
the water hardness in your area. (See page 5.)
♦ Use a good quality dishwasher detergent.
♦ Do not overload the machine. Water should circulate
freely to ensure adequate rinsing and draining.
♦ Fill the rinse aid dispenser (unless you have soft water
in your area; in which case you may not need a rinse
aid). (See page 6.)
♦ Use a lower water temperature setting.
♦ Do not use the Extra Dry setting.
♦ Do not pre-rinse the dishes; just scrape off large food
particles and bones.
