FILTER SYSTEM

Your dishwasher has a multiple filter system, which helps your dishwasher perform better using less water and less energy.
The filter system includes three filters that work in combination to separate dirty and clean water into different chambers a Filter Location

1. Filter Location

SMART WASH SYSTEM

Your dishwasher has a Smart Wash system which can be used by selecting the Auto cycle.
The Smart Wash system senses the soil level of the load and adjusts the wash cycle accordingly. Your dishwasher can determine the type of cycle required to clean the dishes and will clean more efficiently every time.

ADJUSTABLE UPPER RACK

The Adjustable Upper Rack feature allows you to load taller items in either the upper or lower rack.
The upper rack of your dishwasher can be adjusted 2" (5.08 cm). Adjusting the clearance of the Upper Rack increases or decreases the clearance of the lower rack, as shown.
For instructions, see the "Adjustable Upper Rack" section.

START UP GUIDE

• Properly dispose of/recycle all packing material.
• Read this entire User Manual. You will find important safety information and useful operating tips.

HOW YOUR UNIT CLEANS

Your dishwasher cleans by spraying a mixture of hot water and detergent through the spray arms against soiled surfaces.

The dishwasher fills with water covering the filter area. Water is then pumped through the multiple filters and spray arms. Soil particles are separated from the water and go down the drain as the water is pumped out and replaced with clean water.

The number of water fills will vary depending on the cycle selected.

BEFORE USING YOUR DEVICE

1. Check the filters for debris that may have been introduced from the packaging or during installation. See the "Clean Filters" section.
2. Add Rinse Aid. See "Proper Use of Rinse Aid."

USING YOUR NEW DEVICE

UNIT LOADING

PREPARE DISHES

• Empty liquids from glasses and cups.
• Remove leftover food, bones, toothpicks and other hard items from the dishes and discard.
  
• It is not necessary to hand-rinse dishes before loading them into the dishwasher with the following exceptions:
  • Foods such as mayonnaise, mustard, vinegar, lemon juice and tomato-based products may discolor stainless steel and plastics if allowed to remain on them for any length of time.
  • Burned-on foods should be loosened before loading the cookware into the dishwasher.

LOAD DISHES

• It is IMPORTANT for the water spray to reach all soiled surfaces.
• Load dishes so they are not stacked or overlapping if possible. For best drying results, water must be able to drain from all surfaces.
• Load heavy pots and pans carefully. Heavy items can dent the stainless steel interior of the door if they are dropped or bumped.
• Make sure pot lids and handles, pizza pans, cookie sheets, etc., do not interfere with the spray arm rotation.
• Make sure both the upper and lower spray arms are not blocked and move freely.
  

QUIET OPERATING TIPS
To avoid thumping/clattering noises during operation:

• Make sure lightweight items are secured in the racks.
• Make sure pot lids and handles, pizza pans, cookie sheets, etc., do not touch interior walls or interfere with the rotation of the spray arm.
• Load dishes so they do not touch one another.
  NOTE: For built-in models, keep sink drain plugs closed during dishwasher operation to prevent noise transfer through drains.

UPPER RACK

The upper dishwasher rack is designed for cups, glasses, small plates, bowls and plastic items marked dishwasher safe.

The upper rack can be easily adjusted 2" (5 cm) up or down to accommodate taller items in either in the top or bottom rack.

ADJUST UPPER RACK

• Remove all items before adjusting the rack. The rack must be empty.
• Do NOT grasp adjustment arm when raising the upper rack. Grasping the adjustment arm will prevent the upper rack from engaging properly, and damage to dish ware could result if the upper rack releases.

To Raise the Upper Rack:

1. Grasp the uppermost wire on each side of the upper rack, and then lift up until each side clicks.
   
   1. Adjustment Arm

To Lower the Upper Rack:

1. Pull up on the adjustment arm located on each side of the upper rack.
2. Lower the upper rack until the rack is level in the lower position.
   
   1. Adjustment Arm

UPPER RACK SHELF

The upper rack has a shelf to accommodate short glasses, cups or cooking utensils such as spatulas.

To Engage the Shelf:

1. Lift straight up on the shelf.
2. Rotate the shelf to the center of the rack.
   

LOAD UPPER RACK

NOTE: The features on your dishwasher rack may vary from the drawings shown

Make sure the items loaded in the upper rack do not interfere with the rotation of the middle spray arm located beneath the upper rack. Check for interference by turning spray arm by hand.

• Place items so that the open ends face downward for cleaning and draining.
• Load glasses and cups in upper rack only. The lower rack is not designed for glasses and cups. Damage can occur.
• Place cups and glasses in the rows between tines. Placing them over the tines can lead to breakage, water spots, and poor cleaning.
• Small bowls, pans and other utensils can be placed in the top rack. Load bowls in the center section for best stability.
• China, crystal and other delicate items must not touch each other during dishwasher operation. Damage may occur.
• Load plastic items so the force of the spray does not move them during the cycle.

LOWER RACK

The lower rack is designed for plates, soup bowls, cookware and bakeware.

The adjustable upper rack allows you to load items up to 13" in height in the lower rack.

Items in the lower rack must be placed so that they do not interfere with the rotation of the spray arms, block the water inlet, or keep the water spray from reaching the detergent dispenser.

LOAD LOWER RACK

NOTE: The features on your dishwasher rack may vary from the drawings shown.

• Do not load glasses, cups, or plastic items in the lower rack.
• Load small items in the lower rack only if they are secured in place.
• Load plates, soup bowls, etc. between tines. Do not nest bowls because the spray will not reach all surfaces.
• Do not load items between the bottom rack and the side of the dishwasher tub.
• Place heavily soiled cookware face down in the rack.
• Load cookie sheets, cake pans, and other large items along the sides and back of the lower rack.
  

ADJUSTABLE RACK TINES

The fold-down tines in the lower rack make it easier to load extra large or hard-to-fit items such as serving bowls and roasters. The tines may be left in the up position for normal use, or folded down for more flexible loading.

To Lay Tines Down:
Grasp the tip of the tine, gently pull the tine out of the tine holder and rotate the tine to the side.

• Upper Rack - Push the tines to the center of the rack.
• Lower Rack - Push the tines to the back of the rack.

To Stand Tines Upright:
Grasp and pull the tine until it is vertical and/or you feel it click into place. Verify the tines are secure before loading.

• Upper Rack - Push the tines to the right-hand side of the rack.
• Lower Rack - Pull the tines to the front of the rack.
  

LOADING SILVERWARE

NOTES:

• Do not load silver or silver-plated silverware with stainless steel. These metals can be damaged by contact with each other during washing.
• Some foods (such as salt, vinegar, milk products, fruit juices, etc.), can pit or corrode silverware. DO NOT WASH ALUMINUM COOKWARE IN YOUR DISHWASHER.

THIRD RACK

The Third Rack can be used to load cutlery or other accessories such as spatulas or cooking spoons.
Silverware, knives, and utensils should be loaded in the Third Rack separate from each other in the appropriate positions so they do not nest together.

THREE-PIECE SILVERWARE BASKET

The silverware basket consists of three separate sections. For optimum loading flexibility, the center section of the basket can be used individually, joined with one or both side sections or removed.

• Lift handle to remove the silverware basket and set the basket on a counter or table top.
• Lift up on each side section to disengage the center section from the keyhole slots in the side sections.
• Either replace the section(s) in the bottom rack and load the silverware, OR load the silverware while the section(s) are on the countertop and then replace the basket in the bottom rack.
  
  1. Keyhole Slots
  2. Prongs

For Best Results:

• Load items with handles down, using the separators to prevent silverware from nesting.
• Place small items such as baby bottle caps, jar lids, corncob holders, etc. in the section(s) with hinged cover(s). Close the cover to hold small items in place.
• Unload or remove the basket before unloading the racks to avoid water drops from falling on the silverware.
• When handles are up, mix items in each section of the basket with some pointing up and some down to avoid nesting. Spray cannot reach nested items.
  

Always load sharp items (knives, skewers, etc.) pointing down. Be sure that nothing protrudes through bottom of the basket or rack that may block the wash arm.

RECOMMENDED LOAD PATTERNS

NOTE: Remove the cutlery basket for additional space in the lower rack.

1. Spoons
2. Knives
3. Salad Forks
4. Forks
5. Large Spoons
6. Large Forks

APPLIANCE USE

PROPER USE OF DETERGENT

• Use automatic dish washing detergent only. Other detergents can produce excessive suds that can overflow out of the dishwasher and reduce washing performance.
• Add detergent just before starting a cycle.
• Store detergent tightly closed in a cool, dry place. Fresh automatic dishwasher detergent results in better cleaning.

DETERGENT DISPENSER

1. If the dispenser cover is closed, press in on the blue spring latch to release the cover. The cover will slide to the right.
   
   1. Cover
   2. Blue Cover Latch
2. Add the recommended amount of detergent to the detergent cup.
   NOTE: If using dishwasher detergent in the tablet or pac form, place the detergent in the detergent cup, NOT in the tub to maximize the performance of the detergent.
   
   1. Detergent Cup
3. Slide the dispenser cover to the left, and then press down on the ridged arrow to close.
   

HOW MUCH DETERGENT TO USE
The amount of detergent to use depends on the soil level of your load, the type of detergent used and the hardness of your water.

• If you use too little detergent, dishes won't be clean.
• If you have soft water and use too much detergent, glassware will etch.

Water Hardness
Water hardness varies depending on your water source. For the best results, your dishwasher is designed to operate with water that has a hardness of no more than 7 grains per gallon. Test kits are available from all major appliance parts retail outlets. If your water has a hardness over 8 grains per gallon, you may consider installing a water softener or regularly use an additive to enhance the performance of your detergent.

PROPER USE OF RINSE AID

Rinse aid prevents water from forming droplets that can dry as spots or streaks. A small amount of the rinse aid is released into the final rinse water, which allows water to drain from the dishes.
Rinse aid greatly improves drying performance after the final rinse.
Your dishwasher is designed to use a LIQUID rinse aid. Do not use a solid or bar-type rinse aid.

RINSE AID DISPENSER
Under normal conditions, you will need to fill the rinse aid dispenser approximately once a month. Rinse aid is released through an opening in the dispenser. You do not need to wait until the dispenser is empty to refill it. Try to keep it full, but be careful not to overfill it.

1. Open the dishwasher door.
2. Turn the rinse aid dispenser cap counterclockwise and pull up to remove.
   
3. Pour rinse aid into the dispenser until the sight window indicates FULL.
4. You can adjust the amount of the rinse aid released during the rinse. The higher the number the greater the amount of rinse aid released.
   • If your glassware has spots following the cycle, increase the rinse aid setting.
   • If your glassware has streaks after the cycle, decrease the rinse aid setting.
     
   1. Dispenser Cap
   2. Less
   3. More
5. Clean up any spilled rinse aid with a damp cloth.
6. Replace the rinse aid cap, and then turn the cap clockwise to close.

UNIT CARE

CLEANING

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 clean outside of your dishwasher.

Clean the stainless steel door and handle regularly with a clean, soft cloth to remove debris.

Do not use appliance wax, polish, bleach, or products containing chlorine to clean the stainless steel door.

Control Panel
Gently clean the control panel with a clean, soft cloth.

CLEANING THE INTERIOR

The tub is made of stainless steel designed to resist rust and corrosion if the dishwasher is scratched or dented.

Hard water minerals can cause a white film to build up on the inside surfaces, especially just beneath the door area.

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 may cause foaming or create suds.

DOOR GASKET

Clean the steel inner door and tub with a clean, soft damp cloth.

Using a damp cloth, clean around the door gasket regularly to remove food particles.

CONTROL PANEL

Clean the Control Panel gently with a lightly dampened cloth.

CLEANING THE FILTERS

Check and clean the filters regularly for best performance.

1. Remove the lower dishwasher rack.
2. Rotate the Cylinder filter counterclockwise a quarter turn and lift up to remove.
   
   1. Cylinder Filter
3. Empty the Cylinder filter and rinse it under running water.
4. Remove the Fine filter.
   
   1. Fine Filter
5. Remove the Micro filter from the bottom of the tub.
   
   1. Micro Filter
6. Inspect both the Fine filter and the Micro filter for debris, and then clean them by holding the filters under slow running water.
   NOTE: A stiff, plastic bristle brush may be needed to remove some debris.
7. Reinstall the filters in reverse order making sure the Cylinder filter locks into place.

DRAIN AIR GAP

Check the drain air gap anytime your dishwasher isn't draining well. Some state or local plumbing codes require the addition of a drain air gap between a built-in dishwasher and the home drain system. If a drain is clogged, a drain air gap prevents water from backing up into the dishwasher.
The drain air gap is usually located on top of the sink or countertop near the dishwasher.

NOTE: The drain air gap is an external plumbing device that is not part of your dishwasher. The warranty provided with your dishwasher does not cover service costs directly associated with the cleaning or repair of the external drain air gap.

To Clean the Drain Air Gap:
Clean the drain air gap periodically to ensure proper drainage of your dishwasher. Follow the cleaning instructions provided by the manufacturer.

With most types:

1. Turn off the dishwasher.
2. Lift off the metal cover, and then unscrew the plastic cap.
3. Clean the plastic cap with a toothpick.

STORING

STORING FOR THE SUMMER

Protect your dishwasher during the summer months by turning off the water supply and power supply to the dishwasher.

WINTERIZING YOUR DISHWASHER
