5-3. SPECIAL FUNCTIONS

Once you have selected the cycle and other settings, press this button to delay the start
of the wash cycle. Each press of the button increases the delay time by one hour, for up
to 19 hours. Once the desired delay time is set, press the START/PAUSE button to start the 
delay time. If the START/PAUSE button is not pressed  within 4 minutes, the control will 
shut off and  the settings will be lost.

A buildup of detergent residue can occur in the wash tub over time and can lead to a
mildewy or musty smell. The CLEAN WASHER cycle is specially designed to remove this 
buildup using bleach or other cleaner designed specifically for cleaning front load washers.
The CLEAN WASHER cycle should be run once a month, or more often under heavy use 
conditions or if odor is present.

This option will add an extra rinse to the selected cycle. Use this option to help 
ensure the removal of detergent or bleach residue from fabrics.

Use this option for heavily soiled loads that need improved stain treatment. When
STAIN TREAT is selected, the water temperature for the selected cycle will begin
as warm water to help prevent the setting of certain types of stains.  Then as the cycle 
progresses, the water will be heated to higher temperatures to help remove stains that 
require treatment at higher temperatures. This option is designed for optimum stain removal.

NOTE: If STAIN TREAT is selected with the SANITIZE cycle, the cycle will begin with very hot water since that is 

default for that cycle and cannot be changed. 

Turn on the washer and press the CLEAN WASHER button. Selecting any other cycle after 
CLEAN WASHER has been selected will cause the CLEAN WASHER cycle to be cancelled. 
Fill the bleach dispenser to the MAX line with liquid chlorine bleach. Do not overfill the bleach dispenser.
Overfilling will cause the bleach to be dispensed immediately. 
Press the START/PAUSE to start the cycle.

After the cycle has ended, open the door and allow the drum interior to dry completely.

NOTE: Do NOT use this cycle with clothes, and do NOT add detergent or fabric softener.

* For powdered tub cleaners, add the cleaner to the main wash compartment of the dispenser drawer. 

Place tablet cleaners directly into the tub. Always follow the cleaner manufacturers instructions and 
recommendations

STEAM  cycles include the Steam Refresh, Normal/Casual, Bulky/Bedding, Kids Wear,
Heavy Duty and Whitest Whites. Adding steam to these cycles provides superior cleaning 
performance while reducing energy and water consumption. By using a hot steam spray 
from above and cooler water below, fabrics get the cleaning benefits of a super hot wash, 
without the energy usage or potential damage to fabrics.

CAUTION: 
The door may become quite warm during steam cycles.  This is normal.
Do not attempt to override the door lock mechanism or reach into the washer during a steam cycle. 
Steam can cause severe burns.

Steam may not be visible during the steam cycles. This is normal.  

Do not use steam with delicate fabrics such as wool, silk, or easily discolored fabrics.

Turn on the washer and turn the cycle selector knob to select a cycle that allows the steam option. 

Press the ADD STEAM button. The washer will automatically adjust the cycle settings.  
Set any other desired options.  
Press the START/PAUSE button to start the cycle. 

Use this option to disable the controls. The washer can be locked during a cycle. This feature allows you to 
prevent children from changing cycles or operating the machine. Once set, the CONTROL LOCK must be 
turned off before the controls can be used. Once the washer has shut off, the power button will allow the 
machine to be turned on, but the controls will still be locked. When the controls are locked, "CL" will be 
displayed alternately with the estimated time remaining.  

Press and hold the CONTROL LOCK button for 5 seconds to activate or deactivate the controls.
