instructions.

IMPORTANT SAFETY INSTRUCTIONS

WARNING:

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.

■ Do not touch the heating element during or immediately after

use.

■ Do not operate the dishwasher unless all enclosure panels

are properly in place.

When using the dishwasher, follow basic precautions, including the following:

SAVE THESE INSTRUCTIONS

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 INSTRUCTIONS

■ Do not tamper with controls.

■ Do not abuse, sit on, or stand on the door, lid, 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 or lid to the washing compartment

when removing an old dishwasher from service or discarding it.

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 connected dishwasher:

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.

WARNING

Tip Over Hazard

Do not use dishwasher until completely installed.

Do not push down on open door.

Doing so can result in serious injury or cuts.

State of California Proposition 65 Warnings: WARNING: This product contains one or more chemicals known to the State of California to cause cancer. WARNING: This product contains one or more chemicals known to the State of California to cause birth defects or other

What’s New in Your Dishwasher

Energy

Congratulations on purchasing your water and energy efcient dishwasher! This dishwasher cleans by spraying the dishes with water and pauses to allow the detergent to soak into and release the soils on the dishes. The cycles are longer due to the soak and pauses for exceptional cleaning. Several models contain an optical water sensor. The optical water sensor is used to determine the optimum water and energy consumption for great cleaning performance. Efcient dishwashers run longer to save water and energy, just as driving a car slower saves on gas. The rst cycle using the sensor will run longer to calibrate the optical sensor.

Performance

Rinse Aid

Using rinse aid will optimize your drying and wash performance. This dishwasher is specically designed to be used with rinse aid for improved drying performance and controlling buildup of hard water deposits. Energy efcient dishwashers use less water and energy, so they depend on the water “sheeting” action of rinse aid for total optimal performance.

Detergent

The United States and Canada have passed a restriction limiting the amount of phosphorus (phosphates) in the household dishwasher detergents to no more than 0.5%, where previous detergents contained 8.7%. Major manufacturers have reformulated their dishwasher detergent for this change in detergents as another step in eco-conscious awareness. With these recent changes it is recommended to use tablets and packs for convenience and improved performance.

Filtration System

Your dishwasher has the latest technology in dishwasher ltration. This triple ltration system minimizes sound and optimizes water and energy conservation while providing optimal cleaning performance. Maintenance of your lters regularly will sustain peak cleaning performance. We suggest you clean both your upper and lower lter and rinse under running water at least once a month.

STEP 1

Prepare and Load the Dishwasher

IMPORTANT: Remove leftover food, bones, toothpicks and

other hard items from the dishes. Remove labels from containers before washing.

Upper Rack Lower Rack

■ Make sure nothing keeps spray arm(s) from

spinning freely. It is important for the water spray to reach all soiled surfaces.

■ Make sure that when the dishwasher door is closed

no items are blocking the detergent dispenser.

■ Items should be loaded with soiled surfaces facing down

and inward to the spray as shown in the graphics above. This will improve cleaning and drying results.

■ Avoid overlapping items like bowls or plates that may

trap food.

■ Place plastics, small plates and glasses in the upper rack.

■ Wash only items marked “dishwasher safe.”

■ To avoid thumping/clattering noises during operation:

Load dishes so they do not touch one another. Make sure lightweight load items are secured in the racks.

■ When loading silverware, always place sharp

items pointing down and avoid “nesting” as shown. If your silverware does not t into the designated slots, ip the covers up and mix silverware types to keep them separated.

■ Use suggested loading patterns, as shown, to

better clean your silverware.

■ Use the slots in the covers to keep your silverware separated

for optimum wash.

STEP 2

Add Detergent

NOTE: If you do not plan to run a wash cycle soon, run a

rinse cycle. Do not use detergent.

■ Use automatic dishwasher detergent only. Add powder,

liquid or tablet detergent just before starting a cycle.

■ Fresh automatic

dishwasher

detergent results in better cleaning. Store tightly closed detergent container in a cool, dry place.

■ For optimum

performance, tablet detergent is recommended.

■ The amount of

detergent to use

A. Cover latch B. Main wash section C. Pre-wash section

depends on: How much soil remains on the items - Heavily soiled loads

require more detergent. The hardness of the water - If you use too little in hard water,

dishes won’t be clean. If you use too much in soft water, glassware will etch.

Soft to Medium Water (0-6 grains per U.S. gallon) [typical water softener water and some city water]

Medium to Hard Water (7-12 grains per U.S. gallon) [well water and some city water]

■ Depending on your water hardness, ll the Main Wash section

of the dispenser as shown. Fill the Pre-Wash section to the level shown, for heavily soiled items.

NOTE: Fill amounts shown are for standard powdered detergent. Follow instructions on the package when using other dishwasher detergent.

Hard Water Soft Water

Add Rinse Aid

■ Your dishwasher is designed to use rinse aid for good drying

performance. Without rinse aid your dishes and dishwasher interior will have excessive moisture. The heat dry option will not perform as well without rinse aid.

■ Rinse aid keeps water from forming droplets that can

dry as spots or streaks. They also improve drying by allowing water to drain off of the dishes after the nal rinse.

■ Check the rinse aid indicator. Add rinse aid when

indicator drops to “Add” level.

■ To add rinse aid, turn the dispenser

cap Z\v turn counterclockwise and lift off. Pour rinse aid into the opening until the indicator level is at “Full.” Replace the dispenser cap and turn to “Lock.” Make sure cap is fully locked.

NOTE: For most water conditions, the factory setting will give

good results.

■ Check water hardness level to ensure no rings or spots

on your dishware before adding rinse aid or adjusting the factory setting.

■ If you have hard water or notice rings or spots, try a

higher setting.

Turn the arrow adjuster inside the dispenser by either using your ngers or inserting a at-blade screwdriver into the center of the arrow and turning.

STEP 3

Select a Cycle (cycles vary by model)

See “Cycle and Option Descriptions” charts in the following section.

Heavier cycles and options affect cycle length.

STEP 4

Start or Resume a Cycle

■ Run hot water at the sink nearest to your dishwasher until

the water is hot. Turn off water. For best dishwashing results, water should be 120ºF (49ºC) as it enters the dishwasher.

■ For models with controls on top of the door, select wash

cycle, option and press START/RESUME before closing the door. Push door rmly closed. The door latches automatically. Select the wash cycle, options and press START/RESUME or press START/RESUME to repeat the same cycle and options

as in the previous wash cycle.

■ You can add an item anytime at the beginning of the cycle.

Open the door slowly and add the item. Close the door rmly. Press START/RESUME.

Select Options (options vary by model)

See “Cycle and Option Descriptions” charts in the following section.

You can customize your cycles by pressing the options desired.

Cycle and Option Descriptions

This information covers several different models. Your dishwasher may not have all of the cycles and options described. Estimated cycle times may increase or decrease depending on water temperature, soil conditions, dish load size, and options selected. You can customize your cycle by selecting an option.

See option selections. If you change your mind, press the option again to turn off the option, or select a different option. You can change an option anytime before the selected option begins. At each stage of the wash cycle, you may hear noises that you are not used to hearing in your previous dishwasher. Each cycle will provide a series of pauses and water sprays throughout the wash cycle. This is normal and will provide optimal cleaning performance.

to ½ of the way out.

Filtration System

Your dishwasher has the latest technology in dishwasher ltration. This triple ltration system minimizes sound and optimizes water and energy conservation while providing superior cleaning performance. Throughout the life of your dishwasher, the lter will require maintenance to sustain peak cleaning performance.

The triple lter system consists of 2 parts, an upper lter assembly and a lower lter.

■ The upper lter assembly keeps oversized items and foreign

objects, along with very ne food particles, out of the pump.

■ The lower lter keeps food from being recirculated onto your

dishware.

The lters may need to be cleaned when:

■ Visible objects or soils are on the Upper Filter Assembly.

■ There is degradation in cleaning performance (that is, soils still

present on dishes).

■ Dishes feel gritty to the touch.

It is very easy to remove and maintain the lters. The chart below shows the recommended cleaning frequency.

Very Hard Water

If you have hard water (above 15 grains), clean your lter at least once per month. Building up of white residue on your dishwasher indicates hard water. For tips on removing spots and stains, see “Troubleshooting” section.

Filter Removal Instructions

Cleaning Instructions

IMPORTANT: Do not use wire brush, scouring pad, etc. as

they may damage the lters. Rinse lter under running water until most soils are removed.

Dishwasher Care

CLEANING THE DISHWASHER

Cleaning the Exterior

Clean the exterior of the dishwasher with a soft, damp cloth and mild detergent. If your dishwasher has a stainless steel exterior, a stainless steel cleaner is recommended - Stainless Steel Cleaner and Polish Part Number 31464.

Cleaning the interior

Clean the interior of the dishwasher, with a paste of powdered dishwasher detergent and water or use liquid dishwasher detergent on a damp sponge to clean the cooled-down interior.

A white vinegar rinse may remove white spots and lm. Vinegar is an acid, and using it too often could damage your dishwasher.

Put 2 cups (500 mL) white vinegar in a glass or dishwasher-safe measuring cup on the bottom rack. Run the dishwasher through a complete washing cycle using an air-dry or an energy-saving dry option. Do not use detergent. Vinegar will mix with the wash water.

Dishwasher is not operating properly

■ Dishwasher does not run or stops during a cycle

It is normal for certain cycles to repeatedly pause for several seconds during the main wash.

Is the door closed tightly and latched? Is the right cycle selected? Is there power to the dishwasher? Has a household fuse

blown, or has a circuit breaker tripped? Replace the fuse or reset the circuit breaker. If the problem continues, call an electrician.

Has the motor stopped due to an overload? The motor automatically resets itself within a few minutes. If it does not restart, call for service.

Is the water shutoff valve (if installed) turned on?

■ The Clean light is ashing

Check the following:

■ Is the overll protection oat able to move up and down

freely? Press down to release.

■ Be sure the water supply is turned on to the dishwasher.

(This is very important following the new installation of your dishwasher.)

■ Check for suds in the dishwasher. If foam or suds

are detected by the dishwasher sensing system, the dishwasher may not operate properly or may not ll with water.

Subs can come from:

1. Using the incorrect type of detergent, such as laundry

detergent, hand soap, or dish detergent for hand washing dishes.

2. Forgetting to replace the rinse aid dispenser cap after

lling (or relling) the rinse aid.

3. Using an excessive amount of dishwasher detergent.

■ Dishwasher will not ll

Is the overll protection oat able to move up and down freely? Press down to release.

■ Dishwasher seems to run too long

Try the 1 Hour Wash cycle. Is the water supplied to the dishwasher hot enough? The

dishwasher runs longer while heating water. Is the dishwasher cycle time within the cycle times? See cycle

sections wash times. A delay automatically occurs in some wash and rinse cycles until the water reaches the proper temperature.

This dishwasher is equipped with an optical sensor wash that detects water temperature, soil and detergent amount. Wash cycles are adjusted based on the load sensing.

IMPORTANT: The very rst wash cycle after installation in your home will be adjusted to include an additional 2 rinses. This cycle must not be interrupted for proper sensor adjustment. If this adjustment cycle is canceled or stopped before the Clean light comes on at the end of the cycle, the next wash cycle will repeat this sensor adjustment.

■ Water remains in the dishwasher

Is the cycle complete? Was the disposer knockout plug removed during installation?

(See “Install the drain hose” section in the Installation Instructions.)

Detergent remains in the covered section of the dispenser

Is the cycle complete? Check for items such as cookie sheets, cutting boards, or

large containers that may be blocking the detergent dispenser from opening properly.

Be sure the cycle has nished (green light is on). If it has not nished, you will need to resume the cycle by pressing START/ RESUME and closing the door within 3 seconds.

Is the detergent lump-free? Replace detergent if necessary.

■ White residue on the front of the access panel

Was too much detergent used? Is the brand of detergent making excess foam? Try a different

brand to reduce foaming and eliminate buildup.

■ Odor in the dishwasher

Are dishes washed only every 2 or 3 days? Check and clean your lters regularly. See the table in

“Filtration System” section for “Recommended Time Interval to Clean Your Filter.”

Does the dishwasher have a new plastic smell? Run a vinegar rinse as described in “Dishwasher Care.”

To avoid odor, use affresh

dishwasher and disposal cleaner tablet once a month or as needed for a fresher dishwasher as described in “Dishwasher Care.”

■ Condensation on the kitchen counter (built-in models)

Is the dishwasher aligned with the countertop? Moisture from the vent in the dishwasher console can form on the counter. Refer to the Installation Instructions for more information.

■ Bottom rack does not fully slide into the dishwasher

Check to see if items loaded for TargetClean™ wash option have shifted. Reload to keep items from interfering with spray jets or spray arm.

Dishes do not dry completely

■ Dishes do not dry completely

Did you use a rinse aid? Your dishwasher is designed to use rinse aid for good drying performance. Without rinse aid your dishes and dishwasher interior will have excessive moisture. The Heat Dry option will not perform as well without rinse aid.

■ Dishes are not dry

Did you load your dishwasher to allow proper water drainage? Do not overload. Use a liquid rinse aid to speed drying.

Are the plastics wet? Plastics often need towel drying. Is the rinse aid dispenser empty? Did you use an air-dry or energy-saving dry option? Use a

heated drying option for dryer dishes.

■ Excess moisture on racks and dishwasher interior

Check the rinse aid indicator to see that there is rinse aid in the dispenser.

Spots and stains on dishes

■ Spotting and lming on dishes

Is your water hard, or is there a high mineral content in your water? Conditioning the nal rinse water with a liquid rinse aid helps eliminate spotting and lming. Keep the rinse aid dispenser lled. Always use a high-temp option. If your water hardness is 13 grains or above, it is strongly recommended that you install a home water softener. If you do not wish to drink softened water, have the softener installed onto your hot water supply.

Is the water temperature too low? For best dishwashing results, water should be 120°F (49°C) as it enters the dishwasher.

Did you use the correct amount of effective detergent? Use recommended dishwasher detergents only. Do not use less than 1 tbs (15 g) per load. Detergent must be fresh to be effective. Heavy soil and/or hard water generally require extra detergent.

Using dishwasher detergent tablets and packs have been proven better than powder, liquid or gel detergents to reduce lming on your dishes. By using these tablets and packs, over time this will start to reduce or eliminate white lm. Also, by using a rinse aid you can minimize repeat buildup of white lm.

Is the home water pressure high enough for proper dishwasher lling? Home water pressure should be 20 to 120 psi (138 to 828 kPa) for proper dishwasher ll. If you have questions about your water pressure, call a licensed, qualied plumber.

NOTE: To remove spots and lm from glassware, remove all silverware and metal items and run a vinegar rinse as described in “Dishwasher Care.”

■ Silica lm or etching (silica lm is a milky, rainbow-colored

deposit; etching is a cloudy lm)

Sometimes there is a water/chemical reaction with certain types of glassware. This is usually caused by some combination of soft or softened water, alkaline washing solutions, insufcient rinsing, overloading the dishwasher, and the heat of drying. It might not be possible to avoid the problem, except by hand washing.

To slow this process use a minimum amount of detergent but not less than 1 tbs (15 g) per load. Use a liquid rinse aid and underload the dishwasher to allow thorough rinsing. Silica lm and etching are permanent and cannot be removed. Do not use heated drying.

■ White spots on cookware with nonstick nish

Has the dishwasher detergent removed cookware seasoning? Reseason cookware after washing it in the dishwasher.

■ Brown stains on dishes and dishwasher interior

Does your water have high iron content? Rewash dishes using 1-3 tsp (5-15 mL) of citric acid crystals added to the covered section of the detergent dispenser. Do not use detergent. Follow with a Normal wash cycle with detergent. If treatment is needed more often than every other month, the installation of an iron removal unit is suggested.

■ Black or gray marks on dishes

Are aluminum items rubbing dishes during washing? Disposable aluminum items can break down in the dishwasher and cause marking. Hand wash these items. Remove aluminum markings by using a mild abrasive cleaner.

■ Orange stains on plastic dishes or dishwasher interior

Are large amounts of tomato-based foods on dishes placed in the dishwasher? It may be necessary to use a stain removal product to remove stains from your dishwasher. Stains will not affect dishwasher performance.

Noises

■ Surging sounds

Surging sounds can occur periodically throughout the cycle while the dishwasher is draining.

■ Valve hissing

Normal water valve hissing may be heard periodically, during the water ll.

■ Snapping sound

A normal snap sound may be heard when the detergent dispenser opens during the cycle, and when the door is opened at the end of the cycle.

■ Grinding, grating, crunching or buzzing sounds

A hard object has entered the wash module (on some models). When the object is ground up, the sound should stop. If the noise persists after a complete cycle, call for service.

Dishwasher stops and starts

■ Numerous starts and stops

It is normal to hear numerous starts and stops throughout your entire cycle. These starts and stops are needed to provide optimal cleaning performance and energy savings.

■ Depending on cycle selected

Depending on the cycle selected and the soil level sensed by the “Optical Water Sensor” (on some models), you will experience more starts and stops throughout the entire cycle.

Dishes are not completely clean

■ Food soil left on the dishes

Is the dishwasher loaded correctly? Check and clean your lters regularly. See the table in

“Filtration System” section for “Recommended Time Interval to Clean Your Filter.”

Did you choose the cycle that describes the most difcult soil in your dishwasher? If you have some items with heavier soils, use a heavier cycle.

Is the water temperature too low? For best dishwashing results, water should be 120°F (49°C) as it enters the dishwasher.

Did you use the correct amount of fresh detergent? Use recommended dishwasher detergents only. Do not use less than 1 tbs (15 g) per load. Detergent must be fresh to be effective. Heavy soil and/or hard water generally require extra detergent.

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

Is the pump or spray arm clogged by labels from bottles and cans?

Are high suds slowing the wash arm? Do not use soap or laundry detergents. Use recommended dishwasher detergents only.

■ Dishes in the TargetClean™ wash area are not clean

Are the dishes loaded to face the TargetClean™ spray jets? Load soiled dish surfaces to face the back of the dishwasher toward the TargetClean™ spray jets. Tilt the dishes toward the back so water can drain from surfaces, and the lower spray arm can wash the item from below.

NOTE: Loaded items may shift when dish racks are pushed into the dishwasher. Make sure dishes do not interfere with the spray arms, water feed tube, or TargetClean™ spray jets.

Are items loaded so they do not overlap? Load items only one row deep without any overlap so that the TargetClean™ spray jets can reach all surfaces.

Dishes are damaged during a cycle

■ Chipping of dishes

Did you load the dishwasher properly? Load the dishes and glasses so they are stable and do not strike together from washing action. Minimize chipping by moving the rack in and out slowly.

NOTE: Antiques, feather-edged crystal, and similar types of china and glassware might be too delicate for automatic dishwashing. Wash by hand.
