Dishwasher Use

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 and 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 fit into the  

designated slots, flip 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 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 detergent 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, fill 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.

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 final rinse.

 

Check the rinse aid indicator. Add rinse aid  

when indicator drops to “Add” level.

 

To add rinse aid, turn the dispenser cap 

1/4 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.
