GROUNDING INSTRUCTIONS
For a grounded, cord-connected
washer:
This washer must be grounded. In the event
of a malfunction or breakdown, grounding
will reduce the risk of electrical shock by
providing a path of least resistance for electric current. This washer is equipped with a
cord having an equipment-grounding conductor and a grounding plug. The plug must
be plugged into an appropriate outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
WARNING: Improper connection of the
equipment-grounding conductor can result
in a risk of electric shock. Check with a
qualified electrician or serviceman if you are

Installing The Washer
REMOVE TRANSPORT SYSTEM
WARNING
Excessive Weight Hazard
Use two or more people to move and
install washer.
Failure to do so can result in back or
other injury.
IMPORTANT: Position the washer so that the
rear of the unit is within approximately 3 feet
(90 cm) of the final location.
There are 4 bolts in the rear panel of the washer
that support the suspension system during
transportation. These bolts also retain the power
cord inside the washer until the bolts are removed. To remove the bolts:
1. Using a 1/2″ (13 mm) wrench, loosen each
of the bolts.
4. Close the bolt holes with the four transport
bolt hole plugs.
CONNECT THE INLET HOSES
Connect the inlet hoses to the water faucets.
Make sure the washer basket is empty.
1. Using a pair of pliers, check the tightness
of the hose couplings that are attached to
the washer. NOTE: Do not overtighten the
couplings, or damage to the coupling can
result.
2. Attach the hose with the red color indicator
to the hot water faucet, and the hose with
the blue color indicator to the cold water
faucet. Screw on the couplings by hand
until they are seated on the washer.
3. Using a pair of pliers, tighten the couplings
an additional two-thirds turn. NOTE: Do
not overtighten the couplings, or damage
to the coupling can result.
2. Once the bolt is loose, move it to the center
of the hole, and completely pull out the
bolt, including the plastic spacer covering
the bolt, and the cable attached to the bolt.
The power cord will be attached to all 4
bolts inside the washer.
3. Once all 4 bolts are removed, pull the
power cord through the opening of the rear
panel, and close the hose with the attached cap.
4. Turn on the water and check the couplings
for leaks.
NOTE: Replace the inlet hoses after 5 years of
use to reduce the risk of hose failure. Record
the hose installation, or replacement dates on
the hoses for future reference. Periodically
inspect and replace hoses if bulges, kinks,
cuts, wear, or leaks are found.
2-5
ROUTE THE DRAIN HOSE
LEVEL THE WASHER
The drain hose is connected to your washer.
Proper routing of the drain hose protects your
floors from damage due to water leakage.
Carefully read and follow these instructions.
To prevent drain water from going back into
the washer:
• Do not straighten the drain hose, and do not
force excess drain hose into the standpipe.
The hose should be secure, but loose enough
to provide a gap for air.
• Do not lay excess hose on the bottom of the
laundry tub.
Properly leveling your washer prevents excessive noise and vibration. To level the washer:
1. Check the levelness of the washer by
placing a level on the top edge of the
washer, first side-to-side, then front-toback.
If the washer is against a wall, move the
washer out slightly before tipping back. If
the washer is not level, first prop the front
with a wood block (2″ x 4″) and adjust the
feet as necessary; then prop the back and
adjust feet as necessary. Repeat this step
until washer is level.
SECURE THE DRAIN HOSE
1. Drape the power cord over the washer top.
2. Secure the drain hose to the laundry tub
leg, or to the standpipe with the beaded
strap that is provided.

2
If the washer faucets and the drain
standpipe are recessed, place the hooked
end of the drain hose in the standpipe.
Tightly wrap the beaded strap around the
water inlet and drain hoses.
NOTE: Do not force excess drain hose into the
standpipe.
3
2. After the washer is level, use a 5/8″ (17
mm) open-end wrench to turn the nuts on
the feet tightly against the washer cabinet.
All 4 feet must be tightened. If the nuts are
not tight against the washer cabinet, the
washer may vibrate.
3. Slide the washer to its final location.
4. Confirm the levelness of the washer.
COMPLETE THE INSTALLATION
1. Check the electrical requirements. Be sure
that you have the correct electrical supply
and the recommended grounding method
(see “Electrical Requirements”).
2. Check to be sure all parts are now installed. If there is an extra part, go back
through the steps to see which step was
skipped.
3. Check to be sure you have all of your tools.
4. Dispose/recycle all packaging materials.
5. Check to be sure the water faucets are on.
6. Check for leaks around faucets and inlet
hoses.

PRODUCT OPERATION
THEORY OF OPERATION
INTRODUCTION
The KitchenAid Ensemble Front-Loading Automatic Washer presents a number of new
features and operating characteristics quite
different from previous models. In addition to
the introduction of front-loading operation, the
washer contains a number of unique operating
features designed to increase clothes cleaning
ability while offering very high water and energy conservation.
WATER SYSTEM
The water system consists of the hot and cold
water inlet valves, a water temperature sensor,
a water flowmeter and control, and the dispenser distribution system along with a traditional pressure switch.
WATER INLET VALVES
The hot and cold water inlet valves are located
at the back of the washer. These valves receive a control signal from the Central Control
Unit to manage the temperature of incoming
water. The temperatures are determined by
the specific wash cycle selected and a temperature sensor located in the wash tub. To
improve cleaning of heavily soiled clothing and
to provide a sanitizing feature, the water temperature can be increased through the use of a
heating element located in the bottom of the
tub.
The flowmeter is also used to introduce additional water into the tub for higher water levels,
based on cycle requirements.
Flowmeter
DISPENSER DISTRIBUTION
SYSTEM
All wash and rinse water is introduced into the
wash tub through a Dispenser Distribution System located in the top left corner of the washer.
The system consists of a motor that turns a
cam gear. The cam follower will divert the
incoming water to one or more of the follow
water inlet modes:
• Detergent Dispensing
• Bleach Dispensing
• Fabric Softener Dispensing
• Rinse Dispensing (no additives)
Dispenser
Motor
FLOWMETER
Water flow, or the quantity of water introduced
throughout any cycle, is monitored by a flowmeter and Central Control Unit. When the
flowmeter registers a maximum of 10.5 gal
(40 L), and the Central Control Unit has not
detected the pressure switch trip, the water
valves will be shut off and an error code will
show in the digital display.

AIR VENT SYSTEM
As a safety feature, the washer is designed to
allow fresh air to circulate through the tub. An
inlet vent at the rear of the washer brings air
into the tub. The fresh air is vented through the
dispenser assembly vent tube and out the front
of the dispenser drawer cutout.

PRESSURE SWITCH
The pressure switch is located in the top right
rear corner of the washer. This switch senses
water level in the wash tub. The control signal
from the pressure switch is sent to the Central
Control Unit and is used to determine the
amount of water introduced into the wash tub
during the wash cycle.
The pressure switch also senses the suds level
in the wash tub. If excessive sudsing occurs,
the washer starts an automatic suds routine.
The display will show the word “Sud.” The
automatic suds routine adds additional rinse
and drain operations until the suds level is
reduced.
If an overfill condition is detected by the pressure switch, the CCU will turn on the drain
pump and attempt to stop filling.

CENTRAL CONTROL UNIT (CCU)
The Central Control Unit is located at the top
rear of the washer and is enclosed in a control
box. There are no serviceable parts inside the
control box. If diagnostic tests indicate any
component of the CCU is defective, the entire
control box must be replaced.
The CCU receives input from the touchpad/
LED assembly and directly controls the dispenser, drain pump, water inlet valves, door
locking and unlocking solenoids, and heating
element relay. The CCU monitors the pressure
switch, flowmeter, temperature sensor and door
lock switches.
The CCU sends the customer selection input to
the Motor Control Unit for proper motor operation.
The Motor Control Unit is located inside a
plastic control box located in the lower front
corner of the washer cabinet. The control box
is shown with the access door open.
The MCU operates the drive motor at varying
speeds and direction based on inputs received
by the CCU to complete the cycle selected.
The MCU also monitors a tachometer on the
motor to confirm that the drive motor is operating at the proper speed and direction.
Motor Control Unit
DRIVE MOTOR
The drive motor is a three-phase asynchronous induction type that operates at various
speeds and direction based on input voltages
and frequencies. A tachometer on the motor
shaft sends a feedback signal to the Motor
Control Unit indicating the rotation speed and
direction.

PUMP MOTOR
SUSPENSION SYSTEM
A separate pump/pump motor is used to drain
the wash tub.
Pump Motor
The pump motor is 120 VAC and is attached
directly to the pump. The pump has a cleanout
filter located at the front that allows for the
removal of large objects that may have passed
from the basket.
The wash tub is held in position with four shock
absorbers attached to the bottom four corners
of the tub assembly. In addition, the wash tub
is suspended from the top frame of the washer
with two springs attached to the sides of the
unit.
Stability for this suspension system is provided
by three concrete counter weights. Two are
located at the front of the wash tub. One is
positioned at the back of the tub. These counter
weights eliminate the need for the traditional
balance ring.

CYCLES
Sanitary - Cleans heavily soiled colorfast fab-
rics. This cycle combines a super hot water
temperature and fast speed tumbling to help
ensure the removal of heavy soils and stains.
It is recommended that you set your hot water
heater to 120°F (49°C) to ensure proper performance during this cycle. The Sanitary cycle
also helps kill bacteria, even when no bleach is
used. Extra high speed spin helps shorten
drying time.
Whitest Whites - Designed for cleaning loads
of soiled white fabrics with the addition of
bleach. Hot washing temperatures assure optimal bleach activity. An additional rinse provides optimal rinse performance to avoid chlorine residues on your laundry. This cycle combines fast speed tumbling, longer wash time,
and extra high speed spin to shorten drying
time.
Heavy Duty - Washes loads of sturdy, colorfast fabrics, and heavily to normally soiled
garments. This cycle combines fast speed
tumbling, longer wash time, and extra high
speed spin to shorten drying times. If the water
temperature is lower than needed for this cycle,
the heater will warm the water to the optimum
temperature.
Normal/Casual - Washes normally soiled cottons and linens. This cycle combines medium
speed tumbling and high speed spin.
Rapid Wash - Washes small loads of lightly
soiled garments that are needed in a hurry.
This cycle combines fast speed tumbling, a
shortened wash time, and extra high speed
spin to shorten drying time.
Delicate - Washes no-iron fabrics in garments
labeled “Permanent Press,” or “Wrinkle Free,”
or that indicate using a “Gentle” cycle on the
care label. This cycle combines low speed
tumbling and low speed spin to reduce wrinkling.
Silk - Cleans washable silk garments. (Check
label instructions to make sure that garment is
washable.) This cycle gently tumbles and drains
without spinning to gently clean garments and
minimize wrinkling. Since there is no spinning
action, garments will contain a higher amount
of water at the end of this cycle.
Wool - Cleans washable woolen garments.
(Check label instructions to make sure that garment is washable.) This cycle features gentle
tumbling and low speed spin to provide optimum garment care.
Handwash - Cleans hand-washable and special-care garments. Similar to the way garments are hand washed in a sink, the wash
action of this cycle combines periods of low
speed tumbling and soaking. The low speed
spin reduces wrinkling.
