and the

Safety
safety

of others

is very

important.

We have provided many important safety messages in this manual and on your
appliance. Always read and obey all safety messages.
This is the safety alert symbol.
This symbol alerts you to hazards that can kill or hurt you and others.
All safety messages will be preceded by the safety alert symbol and the
word "DANGER" or "WARNING." These words mean:
You will be killed or seriously injured
if you don't follow instructions.
You can be killed or seriously injured
if you don't follow instructions.
All safety messages will identify the hazard, tell you how to reduce the chance of injury,
and tell you what can happen if the instructions are not followed.

IMPORTANT

SAFETY

WARNING

- When using the
dishwasher, follow basic precautions,
including the following:
• Read all instructions before using the
dishwasher.
• Use the dishwasher only for its
intended function.
• Use only detergents or rinse agents
recommended for use in a dishwasher
and keep them out of the reach of
children.
• When loading items to be washed:
1) Locate sharp items so that they
are not likely to damage the door
seal; and
2) Load sharp knives with the handles
up to reduce the risk of cut-type
injuries.
• Do not wash plastic items unless they
are marked "dishwasher safe" or the
equivalent. For plastic items not so
marked, check the manufacturer's
recommendations.

INSTRUCTIONS
• Do not operate the dishwasher unless
all enclosure panels are properly in
place.
• Do not tamper with controls.
• Do not abuse, sit on, or stand on the
door or dish racks of the dishwasher.
• To reduce the risk of injury, do not
allow children to play in or on the
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 such a period, 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.
• Remove the door to the washing
compartment when removing an old
dishwasher from service or discarding it.

• Do not touch the heating element
during or immediately after use.

Tip Over Hazard
Do not use dishwasher until
completely installed.

Electrical Shock Hazard
Electrically ground dishwasher.

Do not push down on open door.

Connect ground wire to green ground
connector in terminal box.

Doing so can result in serious injury
or cuts.

Do not use an extension cord.
Failure to do so can result in death,
fire, or electrical shock.

GROUNDING

INSTRUCTIONS

• For a grounded, cord connected
dishwasher:
The dishwasher must be grounded. In
the event of a malfunction or breakdown,
grounding will reduce the risk of electric
shock by providing a path of least
resistance for electric current. The
dishwasher is equipped with a cord
having an equipment-grounding conductor and a grounding plug. The plug must
be plugged into an appropriate outlet that
is installed and grounded in accordance
with all local codes and ordinances.

WARNING

- Improper connection of
the equipment-grounding conductor can
result in a risk of electric shock.

- SAVE THESE

Check with a qualified electrician or
service representative if you are in
doubt whether the dishwasher is
properly grounded. Do not modify the
plug provided with the dishwasher; if it
will not fit the outlet, have a proper
outlet installed by a qualified electrician.
For a permanently
dishwasher:

connected

The dishwasher must be connected to a
grounded metal, permanent wiring
system, or an equipment-grounding
conductor must be run with the circuit
conductors and connected to the
equipment-grounding terminal or lead
on the dishwasher.

Stopping

the dishwasher

You can stop your dishwasher anytime
during a cycle. All you have to do is:
• Open the door slightly. Wait for any filling
or spraying action to stop before opening
the door all the way. Close door to
continue cycle.
OR
• Press Cancel/Drain. Once pressed, a
2-minute drain starts. See the "Setting the
Controls" section.

Loading Your Dishwasher
This section tells how to properly load your dishwasher for best washing and rinsing results.

Preparing

to load the dishwasher

• To save water and energy, do not rinse
dishes before putting them into the
dishwasher.
• Remove large pieces of food, bones, and
other hard items. The POWER CLEAN TM
module removes food particles from the
water. The module contains a chopping
device which reduces the size of food items.
NOTE- If hard items such as fruit seeds,
nuts, and egg shells enter the POWER
CLEAN module, you might hear chopping,
grinding, crunching, or buzzing sounds.
Those sounds are normal when hard items
enter the module. Do not let metallic items
(such as pot handle screws) get into the
POWER CLEAN module. Damage can
occur.
• Foods like eggs, rice, pasta, and cooked
cereals may be hard to remove if left to dry
over a period of time. Run a Rinse/Wash
Later cycle to keep dishes moist if you do
not plan to wash them soon.
• Load dishes so soiled surfaces face the
rotating spray arm.
• Load dishes so they are not stacked or
overlapping. It is important for the water
spray to reach all soiled surfaces for best
washing. For best drying, water must be
able to drain from all surfaces.

for

quiet

operation

• Secure lightweight load items in the racks.
• Pot lids and handles, pizza pans, cookie
sheets, etc., should not touch interior
walls, interfere with the spray arm's
rotation, or cover the spray tower.
• Load dishes so they do not touch one
another.
NOTE: Keep sink drain plugs inserted
during dishwasher operation to prevent
noise transfer through drains.

the silverware

• Load the silverware basket while it is in the
door or take the basket out for loading on a
counter or table.

• Mix items in each section of the basket
with some pointing up and some down to
avoid nesting. Spray cannot reach nested
items.
IMPORTANT: Always load sharp items
(knives, skewers, forks, etc.) pointing
down.
• Put small items (baby bottle caps, jar lids,
etc.) in any section.
• You can also remove the basket for easy
unloading. Always unload or remove the
basket before unloading the racks to avoid
spilling water on the silverware.
To

remove

the

basket:

1. Grab the basket by the handle and slide
it toward the top of the door.
2. Lift the basket off the holding buttons.

To replace

the

basket:

1. Set the basket on the holding buttons.
2. Slide the basket towards the bottom of
the door until it locks in place.

To open the basket:
• Unhook the latch as shown.
NOTE: Be sure the cover is completely
latched before pulling out the bottom rack
and before closing the dishwasher door.

Using the Dispensers
For best washing results, review the information below. It is important to use detergents and
rinse agents properly.

Using

the detergent

dispenser

• Use automatic dishwashing detergent
only. Other detergents are too mild and
much too sudsy.
• Add detergent just before starting cycle.
• Store tightly closed detergent in a cool, dry
place, Fresh automatic dishwasher
detergent results in better cleaning.

Filling

the

detergent

dispenser

The detergent dispenser has one section
with a cover and one without. Push cover
down firmly until it latches. Detergent in the
open section falls into the dishwasher when
closing the door. The covered section opens
automatically for the main wash.
NOTE: It is normal for the cover to open
partially when dispensing detergent.
Cover

Cover Latch

How
much
detergent
to use
• The amount of detergent to use depends
on the hardness of your water and the type
of detergent. If you use too little, dishes
won't be clean. If you use too much in soft
water, glassware will etch.
• Different brands of dishwasher detergent
have different amounts of phosphorus for
softening water. If you have hard water and
use low phosphorous content detergent
(6.0% or less), you may need to use more
detergent or use a detergent with a higher
phosphorous content (8.7%).
• Find out your water's hardness by asking
your local water department, water softener company, or county extension agent.

when using liquid dishwasher detergent or
concentrated powdered detergent.

Using

the rinse

agent

dispenser

Keep the rinse agent dispenser filled with a
liquid rinse agent. A rinse agent greatly
Improves dish drying by helping water
flow off them during the last rinse. A rinse
agent also keeps water from forming
droplets and drying as spots or streaks,
A small amount of rinse agent automatically releases into the rinse water during the
final rinse of each cycle. For best drying
results, check dispenser periodically to
see if it needs filling.

To check

dispenser:

• Check center of fill indicator cap. Clear
means it needs filling.
OR
• Remove fill indicator cap. An "E" is visible
when dispenser is empty.

Cap center clear
when empty

"E" visible
when empty

To fill dispenser:
The rinse agent dispenser holds 6 ounces
(175 mL). Under normal conditions, this
lasts about 3 months.
1. Open dishwasher door completely.
2. Remove fill indicator cap.
3. Add rinse agent. Fill to smallest opening
in lower part of dispenser only. Overfilling
may cause rinse agent to leak out. This
will not harm the dishwasher, but could
cause oversudsing.

Do not fill past
smallest opening

4. Clean up any spilled rinse agent with a
damp cloth.
5. Replace fill indicator cap. Keep it closed
tightly.
NOTE: You do not have to wait until the
dispenser is empty before refilling, but do
not overfill it. Your dishwasher is designed
to use a liquid rinse agent. You do not need
to use a solid or bar-type rinse agent.

Keep dispenser

filled for best drying results

Caring for Your Dishwasher
Your new dishwasher is designed to give you many years of dependable service. There are
a few things you can do to maintain your dishwasher properly. This section tells you how to
clean and care for your dishwasher. Refer to the "Solution chart" for special cleaning problems. See Installation Instructions for information on storing your dishwasher and for cleaning
the drain air gap.

Caring
(on portable

for simulated

wood

top

models)

The simulated wood top can be used as a
utility work surface for most kitchen jobs. It
is stronger and more easily cleaned than
genuine wood.
The top can be used as a cutting board.
Knife marks will be visible, but will not
seriously damage top. Hot items from the
oven can be placed on the top.
Clean top with warm, soapy water. For
dried-on foods, use a scouring pad.

Cleaning

the exterior

In most cases, regular use of a soft, damp
cloth or sponge and a mild detergent is all
that is necessary to keep the outside of your
dishwasher nice looking and clean.

Cleaning

the interior

Hard water minerals may cause a white film
to build up on the inside surfaces, especially
just beneath the door area.
To clean interior:
• Apply powdered dishwasher detergent to a
damp sponge to make a paste.
OR
• Use liquid automatic dishwasher detergent
and clean with damp sponge.
Do not clean the dishwasher interior until it
has cooled.
Wear rubber gloves. Do not use any type of
cleanser other than dishwasher detergent
because it can cause foaming or sudsing.
NOTE: See "Removing spots and film" in the
"Solving Common Dishwashing Problems"
section to clean your dishwasher with white
vinegar. Remember, this procedure is intended
for occasional use only. Vinegar is an acid.
Excessive use can damage your dishwasher.

Overfill

protector

The overfill protector (in the front right corner
of the dishwasher tub) keeps the dishwasher
from overfilling. It must be in place for the
dishwasher to operate.
Check under the float for objects that may
keep the protector from moving up or down.

Protect your dishwasher and home against
water damage due to freezing water lines. If
your dishwasher is left in a seasonal dwelling or could be exposed to near freezing
temperatures, have a qualified person do
the following:
NOTE: Pump motor styles vary by model.
Refer to Figure 1 or Figure 2, depending on
the style of your dishwasher.

1. Disconnect power supply to the
dishwasher.
2. Turn off water supply to the dishwasher.
3. Remove the 4 screws on the lower
access panel and remove the lower
access panel.
4. Place a shallow pan under the water
supply valve. Then, use a wrench to
disconnect the water inlet from the water
supply valve. Separate the water inlet
from the water supply valve and drain
water into the pan.
5. Remove the spring clamp from the water
outlet and separate from the water
supply valve; drain water into pan.
6. Reconnect both water inlet and water
outlet to the water supply valve.
7. Empty the pan and reposition it under
the water pump.
8. Remove the clamp and disconnect the
drain hose from the water pump; drain
water into pan.
9. Reconnect drain hose to the water
pump, being sure to position the clamp
over the connection.

Saving Energy
Saving energy is important and helps you save money. This section gives you tips on the
best ways to save energy with your dishwasher.

tips

• Wash full loads. Running a half-filled
dishwasher uses the same amount of
electricity and hot water as a fully-loaded
machine.

• Do not prerinse normally soiled dishes.
Select the correct cycle for the load and
use the recommended amount of
detergent.

• Load correctly for best washing results.
Incorrect loading may cause poor washing
and the need to rewash all or part of a load.

Cycle

and option

tips

• Use the Low Energy/China cycle whenever
possible. The cycle uses less hot water
and energy than the Normal cycle.
• Run your dishwasher during off-peak
hours. Local utilities recommend avoiding
heavy usage of energy at certain times
of day.

To check water temperature:
1. Run the hot water at the faucet closest to

• Do not use the High Temp Wash option if
it is not needed. When this option is off, if
water entering the dishwasher is lower
than 140°F (60°C), the cycle does not take
additional time to heat water during the
main wash. In some cases, loads may not
dry as well when using the High Temp
Wash option.
NOTE: Loads may not wash or dry as well
if the water temperature is too low. For
best dishwashing results, water must be
at least 120°F (49°C) as it enters the
dishwasher.

2. Hold a candy or meat thermometer in
the running stream of water.
If water temperature at the
faucet is below 120°F (49°C),
have a qualified person raise
the water heater's thermostat
setting.

• Use the Air Dry option whenever possible.
Allow longer drying times (overnight). Use
a rinse agent to improve drying.

temperature" section.
NOTE: In some cases, loads may not dry as
well when using the High Temp Wash option.

Spotting

Use of incorrect, too
little, or ineffective
detergent

Use recommended dishwasher detergents
only. See the "Using the Dispensers" section.
Never use less than 1 tablespoon per load.
Detergent must be fresh to be effective.
Always store detergent tightly closed in a
cool, dry place.

Detergent cakes in
dispenser

Use fresh detergent only. Do not allow
detergent to sit for several hours in a wet
dispenser. Check dispenser for caked detergent. Clean dispenser when caked detergent
is present.

Insufficient fill due to
low water pressure

Home water pressure should be 20 to 120
pounds per square inch (psi) for proper
dish-washer fill. A booster pump on the
water supply may be necessary if pressure
is too low.

Slowdown of wash
arm due to high suds

Never use soap or laundry detergents. Use
recommended dishwasher detergents only.

Hard water or high
mineral content in

Interior

Large amounts of
tomato-based foods

Stains will not affect dishwasher performance and can gradually fade over time.
Regular use of Rinse/Wash Later reduces
the chance of staining. If air in the dishwasher is heated during the "dry" portion of
the cycle, stains may fade slower than if the
Air Dry option is selected.

Odor in the
dishwasher

Dishes only washed
every 2-3 days

Run a Rinse/Wash Later cycle at least once
or twice a day until a full load is accumulated.

Chipping of
dishes

Improper loading

Load dishes and glasses so they are stable
and do not strike together from washing
action. Moving racks in and out slowly will
also minimize chipping.
NOTE: Some types of china and glassware
are too delicate for automatic dishwashing
and should be hand washed; for example:
antiques, feather-edged crystal, and similar
items.

Removing

spots

and film

Keep the rinse agent dispenser filled with
a liquid rinse agent. A rinse
agent prevents water from
forming droplets and drying
as spots or streaks.
To remove spots and film
on dishes and glasses, or hard water film/
lime buildup on the interior of the dishwasher, you may use white vinegar with
the following procedure:
1. Load clean dishes and glasses in dishwasher. Do not load silverware or other
metals in the dishwasher.

2. Put 2 cups of household vinegar (in a
glass or dishwasher safe measuring cup)
standing upright in the bottom rack.
3. Close and latch the door.
4. Select the Normal cycle and Air Dry
option. Do not use detergent. Allow the
dishwasher to complete the entire cycle.
NOTE: This cleaning procedure is intended
for occasional use only. Vinegar is an
acid. Excessive use may damage your
dishwasher.

reset itself within a few minutes. If it does not start, call for service.
Is the water supply turned on?
Is the dishwasher wired into a live circuit with the proper voltage?

Dishwasher
runs too long

Cycle times depend on the temperature of the water entering the
dishwasher. Cooler water results in longer cycle times.
Undercounter dishwashers require adequate enclosure for proper
operation. See the Installation Instructions for complete information.
