This manual does not cover all possible conditions and
situations that may occur. Common sense and caution
should always be used when installing, operating, and
maintaining any appliance.
♦ Read all instructions before using the dishwasher.
♦ Dishwashers must be electrically grounded. Read
the Installation Instructions for details.
♦ Use the dishwasher only for its intended purpose.
♦ Do not run the dishwasher while you are out of the
home.
♦ Use only automatic dishwasher detergents and
rinse agents.
♦ To reduce the risk of injury, keep detergents and
rinse aids out of the reach of children.
♦ Do not load sharp items near the door; you could
damage the door seal.
♦ Place sharp knives in the silverware basket with the
sharp ends down to avoid the risk of cut-type injuries.
♦ Do not wash plastic items unless they are marked
“dishwasher safe” or the equivalent. For items not
marked, check the manufacturer’s recommendations.
Items not dishwasher safe could become deformed
or melt and create a potential fire hazard.
♦ Do not touch the heating element during or imediately
after use.

panel, toe kick, etc.)
♦ Do not tamper with controls by removing or changing.
♦ Do not abuse, sit on, or stand on the dishwasher
door or baskets .
♦ To reduce the risk of injury, do not allow children to
play in or on a dishwasher.
♦ Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for two weeks or more. HYDROGEN GAS IS
EXPLOSIVE. If the hot water system has not been
used for two weeks, before using the dishwasher
turn on all hot water faucets and let the water flow
from each for several minutes. This will release any
accumulated hydrogen gas. As the gas is
flammable, do not smoke or use an open flame
during this time.
♦ When removing an old dishwasher from service or
discarding it, remove the door to the washing
compartment.
♦ Do not store or use combustible materials, gasoline,
or other flammable vapors and liquids in the vicinity
of this or any other appliance.
♦ Disconnect electrical power to dishwasher before
servicing.
♦ Repairs should be done by a qualified technician.

Your new dishwasher features ASKO’s Super Cleaning
System™. This means that after prewash, mainwash
and intermediate rinse the water is drained out and the
cycle continues with clean water.
LOADING THE UPPER BASKET
After you have scraped off the large food particles, place
glasses, cups, saucers, bowls and small plates in the upper
basket, as illustrated.
Load stemware with the stem fitted inside one of the grooved
tines on the stemware rack.
The fold-down cup shelf on the right side of the basket gives
you an additional place to stack cups and small bowls. You
can also stack items on the stemware rack.
This model has a knife stop on the front of the upper basket.
This gives you a safe place to load long utensils and knives
that won’t fit in the silverware basket. The knife stop prevents
knives or utensils from damaging the door when you open
and close it.
NOTE: When loading sharp items, always be careful not to
cut the rack coating.

The silverware basket is designed with eight compartments to
help keep the silverware separated. Load silverware with the
handles downwards and spread it out as much as possible to
avoid nesting. For safety, load sharp knives with the handles
up.
Avoid placing silverware made of different materials (e.g., silver
and stainless) in the same compartment because of the risk
of discoloration. (See page 14.)

The silverware basket has a lid in the middle that snaps down
over the compartments to its left or right to contain small,
lightweight items that might slip through the rack tines or get
washed out of the basket. The small items lid is slotted, so
you also could use it to keep silverware separated, such as
teaspoons.

ASKO dishwashers are designed to be energy efficient.
Because the machine uses less water than conventional
dishwashers, you also use less detergent and rinse
aid. Generally, only one tablespoon of detergent is
needed for a normal wash load. The amount of detergent
needed for your dishes, however, could be more,
depending on the hardness of the water in your area.
(See below.) Also, more heavily soiled items need more
detergent.
Measure and place detergent for the main wash into the
large detergent compartment. The detergent for prewash
goes into the small compartment to the right of the main
wash compartment. You should use one-half the
amount of detergent for the prewash that you use for the
main wash. The amount of detergent used for the main
wash and prewash combined should never be over
three tablespoons.
Always add the detergent just before starting the
dishwasher, otherwise it could get damp and won’t
dissolve properly.
DISHWASHING DETERGENTDISHWASHING DETERGENT
DISHWASHING DETERGENT
DISHWASHING DETERGENTDISHWASHING DETERGENT
We recommend that you use only unscented, granular
automatic dishwashing detergent. Using the wrong
detergent could cause flooding and/or damage your
dishwasher. Do not use detergent that has been wet
and is clumped. Also, check the expiration date on the
container.
The amount of detergent needed can vary due to
differences in water hardness. To determine the water
hardness in your area, contact your local water utility or
area water softening company. The harder the water,
the more detergent you may need. Refer to the chart
below for the recommended detergent amounts based
on water hardness. Remember, you should adjust the
amount of detergent you use by small amounts until
you find the correct amount.
NOTE:Model D3251FIWS has a water softener
container. See page 6 for more details.
NOTE:We recommend that you do not add
prewash detergent for the Delicate or Quick
wash programs.
NOTE:If you use a dishwashing detergent with a
rinse aid additive, you should not fill the
rinse aid dispenser. This could cause a film
on your dishes.

Twelve grains and higher is extremely hard water and
detergent alone may not be enough. You may need to
use a water softener to maximize the performance of
your dishwasher. (Model D3251FIWS is equipped with
an internal water softener. See page 6 for details.)
In areas with extremely hard water (9+) you may need to
wash at lower temperatures to prevent hard water
deposits from forming in the tank and wash system.
Also, both the dishes and the machine can develop a
white or gray film after a while. This can be removed by
replacing the prewash detergent with two tablespoons
of citric acid. If the water is very hard, use a rinse aid that
contains citric acid.
Different brands of dishwasher detergent have different
amounts of phosphorous for softening water. If you have
hard water and use a detergent with less than 8.7%
phosphorous content, you may need to use more
detergent or use a detergent with more than 8.7%
phosphorous content.

The rinse aid is released during the final rinse to prevent
water from forming droplets on your dishes that can
leave spots and streaks. It also improves drying by
allowing water to “sheet” off the dishes.
ASKO dishwashers are designed to use liquid rinse
aids. The rinse aid dispenser is located inside the door
next to the detergent dispenser. (See illustration on page
3.) To fill the dispenser, open the cap and pour the rinse
aid into the dispenser until the level indicator turns
completely black. The dispenser holds about four
ounces of liquid rinse aid.
Be careful not to overfill the dispenser, because this
could cause oversudsing. Wipe away any spills with a
damp cloth. Don’t forget to replace the cap before you
close the dishwasher door.
If you have soft water, rinse aid may cause a white film to
develop on your dishes. You may not need rinse aid.
NOTE:If you use a dishwashing detergent with a
rinse aid additive, you should not fill the
rinse aid dispenser. This could cause a film
on your dishes.

A measured amount of rinse aid is released during the
final rinse. As with detergent, the amount of rinse aid
needed for your dishes depends on the hardness of the
water in your area. (See page 5.) Too much rinse aid
can result in lather or foaming and cause cloudiness or
streaks on your dishes. If the water in your area is very
soft, you may not need rinse aid. If you do, you can dilute
the rinse aid with an equal amount of water.

The rinse aid dispenser has six settings. Always start
with the dispenser set on “1.” If spots and poor drying
are problems, increase the amount of rinse aid
dispensed by removing the dispenser lid and rotating
the dial to ”2.” If the dishes still aren’t drying properly or
are spotted, adjust the dial to the next higher number

For your convenience, we have placed the drain pump
and filtering system within easy reach inside the tub.
There are three components of the filtering system: the
main filter, the coarse filter, and the fine filter.
In hard water areas, it may be necessary to clean
chemical buildup from the filters every 12 to 18 months.
Main filter
Food and soil particles trapped by this filter are
pulverized by a special jet on the lower spray arm
and washed down the drain.
Fine filter
This filter holds soil and food residue in the sump
area and prevents it from being redeposited on the
dishes during a cycle.
Coarse filter
Larger items, such as pieces of bone or glass, that
could clog the drain are trapped in the coarse filter.
To remove an item caught in this filter, gently
squeeze the tabs on top of this filter and lift it out.

to repeat this process a few times to remove hard water
deposits.
To do this, remove the coarse filter by squeezing the
tabs and lifting it out. Next, unscrew the fine filter and lift
it and the main filter out. Wash all three filters gently in
hot, soapy water and rinse them thoroughly.
WARNING!
Never run the dishwasher without the filters in place.

CLEANING THE DRAIN PUMPCLEANING THE DRAIN PUMP
On occasion something may get through the filters and
into the drain pump. The drain pumps on ASKO
dishwashers are designed to automatically reverse if
anything should get caught in the propellers, thus
ejecting the item back into the sump area or down the
drain. Should you need to remove an obstacle from the
drain, first turn the power off then remove the filters (as
explained on page 9). Next, lift out the adaptor piece on
the left side of the sump area. (You might want to remove
any standing water first.) You can then look into the sump
area for the item causing the obstruction. You may need
to use your finger to move the pump blade and loosen
the object. Should you find something, simply scoop it
out then replace the adaptor piece and the filters.
WARNING!
Never run the dishwasher without the filters in
place.
WARNING!
Never use a spray cleaner of any
kind on the door panel. You could
damage the door lock and
electrical components. Never use
abrasive cleaners or scouring
pads on the outer
surfaces because they
will scratch the finish.
Also, some paper
towels can scratch or
leave marks on the
stainless steel surface.
To reach an item caught in the drain
pump, remove the
filters then the
small black insert
in the sump area.
WARNING!
Be sure to replace the adaptor piece before you put
the filters back in.

Your ASKO dishwasher has an overfill protection device
that automatically shuts off the inlet valve and circulation
pump and starts the drain pump if the water level in the
unit should rise above the normal level. If this happens,
turn the water off at the main supply and call for service.

♦ Unload the bottom basket first to avoid spilling water
onto the dishes when unloading the top basket.
♦ Certain plastics may need to be towel dried.
Plastic items
♦ Always check the manufacturer’s suggested care
instructions before washing plastic in your
dishwasher.
♦ Some high-acid foods can discolor plastic. You
should rinse these items if you do not plan to run the
dishwasher right away.
♦ Plastic items dry poorly and may need to be towel
dried.
Chipped or Broken Dishes
♦ When you load the dishes, be sure they’re securely
in place and will not fall over or strike against each
other during the wash.
♦ Load glasses between the tines, not straddling them.
♦ Move the baskets in and out slowly to avoid
slamming the dishes together.
♦ Make sure not to load dishes so high that the spray
arms could strike them.
♦ Make sure tall glasses and stemware will clear the
top of the tub when you push the basket in.
♦ Always load delicate items in the top basket.
♦ Do not overload the dishwasher.
♦ Do not jam the glasses together when loading.

Poor drying performance
♦ Select the Heated Dry option.
♦ If you don’t want to use Heat Dry, you can decrease
the drying time by opening the door slightly to let out
the warm, humid air.
♦ Make sure the rinse aid dispenser is filled. (See
page 7.)
♦ Make sure you use the proper amount of rinse aid.

♦ Load items with concave bottoms tilted so as much
water as possible will run off.
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 14.
♦ 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. If your model does not have a

softener container, you should consider installing a
water filtering system.
♦ If you have a model with a softener container, make
sure the container has salt and is set correctly (See
page 6.)
♦ 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 a good quality dishwasher detergent.
♦ Use less detergent. You may be using too much for
the water hardness in your area. (See page 5.)
♦ If you have a model with a softener container, make
sure the container has salt and is set correctly (See
page 6.)
♦ Do not overload the machine. Water should circulate
freely to ensure adequate rinsing and draining.

If you should experience a problem with your dishwasher,
you should review the list of frequently encountered
situations on page 13. It could save you the cost and

is not caused by defective product workmanship or
materials, you will be charged for a service call. Refer to
page 16 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.

Detergent left in compartment
♦ Be careful not to load items so close to the dispenser
that the cover will not open to release the detergent.
♦ The dispenser is not supposed to open when you
use the Rinse program.
♦ Your dishwasher detergent should be fresh and
stored tightly closed in a cool, dry place. Old or caked
detergent should be thrown away because it will not
dissolve properly and will leave a gritty residue on
the dishware.
♦ Wait until you are ready to start the dishwasher to
add the detergent.
♦ If you are using the Delay program, make sure the
dispenser is dry before adding the detergent.
♦ The detergent compartment only opens in the main
wash programs, not the Rinse program.
Dishwasher makes unusual noises
♦ This usually means that something is not loaded
properly. Make sure the dishes are securely in place
and that nothing has fallen between the basket tines.
Also, place small items in the small items
compartment and close the lid. (See page 4.)
Dishwasher leaks
♦ Use only unscented, granular automatic dishwasher
detergent. Using a liquid detergent could cause
oversudsing and leakage.
♦ You should always use fresh detergent.
♦ The amount of detergent needed for your dishes
depends on the hardness of the water in your area.
Contact your local utility company to learn the water
hardness in your area then refer to the chart on page
5 to determine the amount of detergent you should
use.
♦ Be careful not to overfill the rinse aid dispenser.
Spilled rinse aid could cause oversudsing and lead
to overflowing. Wipe away any spills with a damp
cloth.
♦ Make sure the dishwasher is level. (See the
installation instructions.)
Dishwasher does not drain properly
♦ Make sure that the cycle was complete before you
opened the dishwasher. If not, allow it to complete
and check again.
♦ Some water left in the sump area near the drain is
normal.
♦ If the plumbing code in your area requires an air
gap, make sure that the air gap isn’t blocked or
plugged.
♦ If the unit is connected to a garbage disposer, make
sure the disposer is empty.
♦ If water backs up into the sink, check the garbage
disposer and trap for blockage.
♦ Check the dishwasher filters and drain area for
blockage. (See page 10.)
♦ Check for a kink in the drain hose.
Dishwasher does not fill properly
♦ Make sure the water supply is turned on.
♦ Make sure the dishwasher is turned on and the door
is closed securely.
♦ Check for crimps in the water feed line.
♦ The system is designed to detect an overflow. When
it does, it shuts off the inlet valve and circulation pump
and turns on the drain pump. (See “Overfill
Protection” on page 11.)
Dishwasher will not start
♦ Make sure the dishwasher is turned on and the door
is closed securely.
♦ Make sure the Delay option is not turned on.
♦ Check that the water supply is connected properly
and the water is turned on.
♦ Make sure the power cord is properly plugged into
the wall socket.
♦ Check your fuse box for a blown fuse or tripped circuit
breaker.
Dishwasher runs too long
♦ If the temperature of the water entering your dishwasher
is below 120°, the dishwasher runs longer because it
heats the water to the proper temperature for the
program selected. Raising your water heater setting
may help to shorten the cycle times. If this doesn’t
resolve the problem, call the ASKO Advisory Center.
