DETERGENT DISPENSER
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. Also, more heavily
soiled items need more detergent. (See below.)

Compartment
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.

keep it out of reach of children.
NOTE:
We recommend that you do not add
prewash detergent for Quick or Glass
wash programs.
DISHWASHING 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.
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:
We recommend that you do not add
prewash detergent for the Quick or Glass
wash programs.
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
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.

detergent alone may not be enough. You may need to
use a water softener to maximize the performance of
your dishwasher. Also, in areas with hard water (9+) you
may need to wash at lower temperatures to prevent
hard water deposits from forming in tank and wash
system.
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.
In hard water areas, both the dishes and the machine
can develop a white or gray film after a while. This can

RINSE AID DISPENSER
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.
Open
Closed
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 up to the knob for dosage setting.
The dispenser holds about four ounces of liquid rinse
aid.
Dispenser
Cap
1. To open the dispenser, turn the cap to the “open”
(left) arrow and lift it out.
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.
2. Pour the rinse aid into the dispenser, being careful
not to overfill.
3. Replace the cap by inserting it aligned with “open”
arrow and turning it to the closed (right) arrow.
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.
ADJUSTING THE AMOUNT OF RINSE AID DISPENSED
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 until your dishes
are spot-free.
To increase the amount of rinse aid released in the
final rinse, turn the adjustment dial to the next
higher number.
Rinse aid

NOTE: Only adjust the dial one number at a time.
RINSE AID INDICATOR
Model D3731 has an indicator in the display window
that displays when the rinse aid dispenser is nearly
empty. After you refill the dispenser, there may be some
delay before this indicator goes out.

Drying
PROGRAM TIMES
This lets you select how long the turbo fan runs after
the final rinse. You have three options: Short, Economy
or Normal drying. (Note: This option is not available
with the Pots & Pans and Rinse and Hold programs.)
To set the drying time, press Menu until “Drying”
displays, then press Set until your preference displays.
The program times may not always be the same
because of variations in the household hot water
temperature. The dishwasher heats the water to the
proper temperature for the program selected; so if the
temperature of the water entering the dishwasher is too
low, the dishwasher will run longer because it takes
longer to heat the water. Raising your water heater
setting could help to shorten the cycle times.
Express
This option reduces the wash time and lowers the wash
temperature by 20° F. (Note: This option is not available
with the Quick Wash, Pots & Pans and Rinse and Hold
programs.) Press Menu until Express displays, then
press Set once to select On or twice to select Off. Press
Menu to confirm your selection.
INTERRUPTING A PROGRAM
TO ADD AN ITEM

the door slightly until the spray arms stop turning. You
can then open the door fully and place the item into the
dishwasher. Close the door securely. The program will
continue from where it was interrupted.
Super rinse
The Super rinse option adds two extra rinses. This
gives an even better rinsing result. The Super rinse
option can be used in all programs except the Quick
wash and Rinse and Hold programs. Press Menu until
Super rinse displays, then press Set once to select On

CARE AND CLEANING
The interior of your ASKO dishwasher is made of
surgical quality stainless steel that has been electro-
polished to make it the smoothest surface available.
The smooth surface prohibits the accumulation of dirt
and bacteria inside the unit. If the water in your area is
especially hard, however, lime deposits could form
inside the machine. If this happens, you can remove
them by putting two tablespoons of citric acid in the
detergent compartment and running a Normal program.
In extremely hard water areas you may need to repeat
this process a few times to remove hard water deposits.
CLEANING THE FILTERS
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.
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.
In hard water areas, it may be necessary to clean
chemical buildup from the filters every 12 to 18 months.
WARNING!
Never run the dishwasher without the filters in
place.
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.
CLEANING THE DOOR
WARNING!
Never use a spray cleaner of any
kind on the door panel. You could
damage the door lock and
electrical components. And 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
To clean the edge around the door, use only a soft warm,
damp rag. To prevent penetration of water into the door
lock and electrical components, do not use a spray
cleaner of any kind.
Also, never use abrasive cleaners or scouring pads on
the outer surfaces because they will scratch the finish.
Some papers towels can also scratch or leave marks on
the surface.
surface.
CLEANING THE DRAIN PUMP
To reach an item caught in the drain pump, remove the
filters then the small insert in the sump area.
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 impeller, 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 7). 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!
WARNING!
Be sure to replace the insert before you put the
filters back in.
Never run the dishwasher without the filters in place.
Page 9
OVERFILL PROTECTION
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.
If there is water in the base pan due to an overfill or
small leak, the water must be removed before the
dishwasher will start.
When an overfill is detected, the display window will show
a fault message. (See “Fault Codes” on page 8.)
ENERGY SAVING TIPS
♦ If you plan to wash the dishes right away, there’s no
need to pre-rinse. Simply scrape off large particles
and load the dishes.
♦ Wash only full loads.
♦ Use the Heavy Wash or Pots and Pans program
only for heavily soiled dishes.
♦ Use the Express option when washing only slightly
soiled loads.
♦ Use the “Economy” drying option. (You can speed
up the drying process by opening the door slightly to
release the moist air.)
♦ Don’t use temperatures above 130°F for lightly soiled
dishes.
SOLUTIONS TO COMMON DISHWASHING PROBLEMS
As with any new appliance, it sometimes takes using it a
few times to learn to operate it properly. If you are having
minor performance problems with your dishwasher, read
this section before calling for service. It may save you
time and unnecessary expense.
NOTE: ASKO has no control over what is put in our
appliances once installed in a customer’s home. You are
solely responsible for what you wash in your ASKO
dishwasher.
Poor washing performance
♦ The dishes may not be loaded properly. Make sure
that soiled surfaces are facing downward or toward
the center of the dishwasher. Also, make sure that
the bowls, pots, etc., are not stacked so closely that
water can’t reach the soiled surfaces.
♦ Load items with concave bottoms tilted so as much
water as possible will run off.
♦ 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.
♦ Load the machine full (1/2 load doesn´t give as good
drying result).
♦ Make sure you are using the appropriate program
settings for the dirtiness of your dishes.
♦ Choose a stronger program and/ or a higher
temperature.
Plastic items
♦ Always check the manufacturer’s suggested care
instructions before washing plastic in your
dishwasher.
♦ An item may be obstructing the spray arm rotation.
With the baskets loaded and in place, manually turn
the spray arms to make sure they move freely.
♦ Your dishwasher detergent should be fresh and stored
tightly closed in a cool, dry place. Old or caked
detergent will not dissolve properly. 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.
♦ Your dishwasher detergent may be inferior. Try a
different brand.
♦ 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.
♦ Make sure the rinse aid dispenser is filled. (See page 6.)
♦ If you have hard water in your area, try adding more
detergent and increasing the amount of rinse aid
dispensed. (See page 4-5.)
♦ Load glasses between the tines, not straddling them.
♦ Move the baskets in and out slowly to avoid slamming
the dishes together.
♦ Check that the spray arm jets are not clogged.
♦ Do not overload the dishes and be careful to avoid
nesting.
♦ 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.
Poor drying performance
♦ Select the Normal drying setting.
♦ If you don’t want to use Normal drying, you can
decrease the drying time by opening the door slightly
to let out the warm, humid air.
♦ Do not jam the glasses together when loading.
♦ Make sure the rinse aid dispenser is filled. (See
page 5.)
♦ Make sure you use the proper amount of rinse aid.
(See page 5.)

SOLUTIONS TO COMMOND DISHWASHING PROBLEMS, continued
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 13.
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 Normal drying setting.
♦ Do not pre-rinse the dishes; just scrape off large food
particles and bones.
♦ 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.
REMOVING HARD WATER SPOTS FROM DISHES
To remove hard water spots, try the following:
1. Run dishes through a normal wash program.
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.
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
TROUBLESHOOTING
If you should experience a problem with your dishwasher,
you should review the list of frequently encountered

♦ The system is designed to detect an overflow. When
it does, it shuts off the circulation pump and inlet
valve and turns on the drain pump. (See “Overfill
Protection” on page 10.)
♦ 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.
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
♦ Be careful not to overfill the rinse aid dispenser.
Spilled rinse aid could cause oversudsing and lead

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
♦ Make sure the dishwasher is level. (See the
breaker.
installation instructions.)
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 Customer Care Center.

WASHING SPECIAL ITEMS
Most common dishware items can be safely washed in
an automatic dishwasher. If you have any doubts about
a particular item, check with the manufacturer to see if it
is dishwasher safe. If that isn’t possible, you might wash
one item of a set a few times and compare it to the rest
of the set to determine if washing it in the dishwasher
had any affect on it.
NOTE: ASKO has no control over what is put in our
dishwashers once installed in a customer’s home. You
are solely responsible for what you wash in your
ASKO dishwasher.
Dishwasher
Material
Safe
Information and Recommendations
Aluminum
Yes, with
caution
Anodized aluminum may fade or darken. Patches and discoloration may appear,
but they can be removed with steel wool. Load aluminum utensils (such as a pie
tin or roasting pan) where they do not touch other dishes because this can cause
gray or black marks. You can remove these spots with a nonabrasive cleaner.
Cast Iron
China
No
The seasoning is lost and the iron rusts. Hand wash and dry immediately.
Yes, with
caution
China without decoration or with decoration protected by glaze is dishwasher
safe. However, you should arrange the objects so they do not touch each other or
they could be damaged.
China with a pattern on top of the glaze or with gold leaf decoration may fade. If
possible, check with the manufacturer. If that isn’t possible, wash one item over
an extended period then compare it with the colors and patterns of the rest of the
set. Wash in the Quick program on a low temperature setting.
Copper
Crystal
Yes, with
caution
Do not wash copper in the same load as silver or silver plate. It could discolor the
silver items. Do not let copper items come in contact with stainless steel.
No
Antiques and very delicate china should not be washed in the dishwasher. Certain
types of lead crystal may etch if machine washed. Check with the manufacturer.

the silver. Also, adhesives used to attach some hollow-handled knives can loosen.
