Dishwasher Use

Prepare and Load the Dishwasher
IMPORTANT:
 Remove leftover food, bones, toothpicks, and 

other hard items from the dishes. Remove labels from containers 

before washing.

 

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 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.

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 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. It also improves 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 

¼ 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.
