Electrical Shock Hazard
Disconnect power before servicing.
Failure to do so can result in death or
electrical shock.
Replace all parts and panels before operating.
TEST #10: Dispenser System
Perform the following checks if the washer will not dispense
detergent or fabric softener.
1. Check water supply to washer. Check water hose
connections to and inside the washer.
2. Verify that dispenser drawer is not clogged with
detergent.
3. Unplug washer or disconnect power.
4. Remove the top panel to access the dispenser.
5. Verify that the inlet valve is working through TEST #5 on
page 3-10. The water is dispensed as follows:
¾ Detergent Dispenser: Through prewash and main wash
valves
¾
Fabric Softener: Through main wash valve
Dispenser Assembly (see Figure below)
A. Liquid fabric softener compartment
Automatically dilutes and dispenses liquid fabric softener at
the optimum time in the cycle.
• Use only liquid fabric softener in this dispenser.
B. Prewash compartment
When using the PreWash option, add detergent here or
directly into the drum.
C. Main wash compartment
This compartment holds liquid or powdered HE detergent
for your main wash cycle. If the PreWash option has been
selected, use powdered detergent in the main wash
compartment ; this ensures that the detergent stays in the
detergent dispenser until the start of the main wash phase.
IMPORTANT : Do not use chlorine bleach in this washer.

Actuation of the door lock solenoid should be heard. At that point, unplug the washer and disconnect
J43
from the ACU and measure
resistance across pins 2 & 3 (ACU side). Resistance should measure according to the following char
t:
¾
If resistance values are good, go to step 6.
¾
If any of the measurements are out of range, check the har
ness of the suspected
component between the ACU and door lock mechanism for continuity
.
¾
If the har
ness and connections are
good, replace the door lock mechanism. IMPOR
TANT
: To
minimize risk of damage
to door lock/switch wires, remove the door lock mechanism screws before removing the front panel.

If the preceding steps did not cor
rect the
lock problem, replace the ACU and retest door lock mechanism.

OTHER OPTIONS
Save Time
This option enables quicker washing. Only
recommended for lightly soiled laundry.
Extra Rinse
This option helps to avoid detergent residues
in the laundry by extending the rinse time.
Especially suitable for baby laundry, people
with allergies, or areas with soft water.
Heavy Soil
This option optimizes the stain-removal efficiency
of additives. Ideal for heavily soiled, stained laundry.
Add an appropriate amount of powder in-wash
additive for stain removal to the main wash
compartment, together with your detergent
(powder only). This may extend the program
by up to 15 minutes. Appropriate for use with
oxygen-based stain removers.
IMPORTANT: Chlorine or perborate bleach agents
must not be used.
Cold Water PreWash for Stains
This option helps remove all kinds of stains (except
grease/oil) by beginning with a cold water wash and
adding 10 minutes to the cycle.
NOTE: Pretreatment is recommended for stubborn
stains.
Warm Rinse
This option ends with a warm rinse. This rinse relaxes
the fibers of your laundry to make it feel comfortably
warm when removed soon after the program/cycle
ends.
PreWash
This option helps to clean heavily soiled laundry by
adding a 20-minute prewash to the program/cycle
selected.
Control Lock
This option allows you to lock the buttons and knob
to avoid unwanted use by small children or other
unqualified persons. Touch and hold the Option
button until the “key” symbol lights up. All controls
will be locked except for the Power button. To cancel
Key Lock, touch and hold the Option button until the
key symbol goes off.
START/PAUSE BUTTON
Touch to start, or touch and hold to pause, a program/
cycle. When you start a program/cycle, the display shows
an animation of chasing LEDs. This indicates the washer
is estimating dry load size. Once the load size is estimated,
water will be added to start the wash cycle.

at the optimum time in the cycle.
Q
Use only liquid fabric softener in this dispenser.
Prewash compartment
When using the PreWash option, add detergent here or
directly into the drum.
Main wash compartment
This compartment holds liquid or powdered HE detergent
for your main wash cycle. If PreWash detergent has been
added to the drum, use powdered detergent in the main
wash compartment; this ensures that the detergent stays
in the detergent dispenser until the start of the main wash
phase.
IMPORTANT:
Do not use chlorine bleach in this washer.

Dispenser Drawer
The dispenser drawer gives you the convenience of adding
HE detergent and liquid fabric softener to the wash load at the
proper time. See “Using the Dispenser Drawer” for information
on using the dispenser drawer.
C
LED DISPLAY
When you select a program/cycle, its default settings will
light up and the Estimated Time Remaining will be displayed.
Factors such as load size, wash temperature, and water
pressure may affect the time shown in the display. Tightly
packing, unbalanced loads, or excessive suds may cause
the washer to lengthen the program/cycle time, as well.
Symbols
Door can be opened.
Water supply is inadequate.
Water cannot be drained. Drain pump filter, drain hose,
or pump may be blocked. Check drain hose for kinks
or clean the filter as shown in “Washer Maintenance.”
