Whirlpool DP840 用户手册

Mix items in each section of the basket with some pointing up 
and some down to avoid nesting. Spray cannot reach nested 
items.

■

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. Run a rinse cycle if you do 
not have a full load to wash immediately.

■

Unload or remove the basket before unloading the racks to 
avoid spilling water droplets on the silverware.

The detergent dispenser has 2 sections. The Pre-Wash section 
empties detergent into the dishwasher when you close the door.

The larger Main Wash section automatically empties detergent 
into the dishwasher during the main wash. (See the “Cycle 
Selection Charts.”)

■

Use automatic dishwashing 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 tightly closed detergent in a cool, dry place. Fresh 
automatic dishwasher detergent results in better cleaning.

NOTE: Do not use detergent if you have selected a rinse cycle.

1. If the dispenser cover is closed, open the cover by pushing 

the cover latch.

2. Fill the Main Wash section with detergent. See “How much 

detergent to use.”

3. Fill the Pre-Wash section if needed. (See “Cycle Selection 

Charts.”)

4. Close the dispenser cover.

The cover will open during the cycle to dispense the detergent.

■

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.

■

Water hardness can change over a period of time. Find out 
your water’s hardness by asking your local water department, 
water softener company, or county extension agent.
