Whirlpool W10420378A User Manual

Pour a measured amount of liquid  

fabric softener into tray, always 

follow manufacturer’s directions for correct amount of  

fabric softener based on your load size. Close dispenser  

drawer, then select Fabric Softener option. 
IMPORTANT: Fabric Softener option must be selected  

to ensure proper distribution at correct time in cycle.  

Do not overfill or dilute. Overfilling dispenser will cause  

fabric softener to immediately dispense into washer. 
If Extra Rinse option is selected, fabric softener will be 

dispensed into the last rinse.
It is normal for a small amount of water to remain in the 

dispenser at the end of a cycle. 

Do not overfill, dilute, or use more than 1 cup (250 mL).  

Do not use color-safe bleach or Oxi products in the same  

cycle with liquid chlorine bleach.

Bleach

Add a measured amount of  

HE detergent into detergent tray. This  

tray holds 3 oz. (89 mL). Do not overfill tray - adding too much 

detergent may cause detergent to be dispensed into the washer 

too early.
IMPORTANT: Use only High Efficiency detergents. The package 

will be marked “HE” or “High Efficiency.” Low-water washing 

creates excessive sudsing with a regular non-HE detergent. 

Using regular detergent will likely result in longer cycle times  

and reduced rinsing performance. It may also result in 

component failures and noticeable mold or mildew. HE 

detergents are made to produce the right amount of suds  

for the best performance. Follow the manufacturer’s instructions 

to determine the amount of detergent to use. 
Using Oxi or color-safe bleach:

If using an Oxi or color-safe bleach laundry boost product,  

add to the bottom of the washer basket before adding clothes.
HELPFUL TIP: See “Washer Maintenance” for information  

on recommended method of cleaning washer dispenser trays.
