INTRODUCTION
The KitchenAid Ensemble Front-Loading Au-
tomatic 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 en-
ergy 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 dis-
penser distribution system along with a tradi-
tional pressure switch.
WATER INLET VALVES
The hot and cold water inlet valves are located
at the back of the washer. These valves re-
ceive 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 tem-
perature sensor located in the wash tub. To
improve cleaning of heavily soiled clothing and
to provide a sanitizing feature, the water tem-
perature can be increased through the use of a
heating element located in the bottom of the
tub.
FLOWMETER
Water flow, or the quantity of water introduced
throughout any cycle, is monitored by a flow-
meter 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.

THEORY OF OPERATION

The flowmeter is also used to introduce addi-
tional water into the tub for higher water levels,
based on cycle requirements.

DISPENSER DISTRIBUTION
SYSTEM
All wash and rinse water is introduced into the
wash tub through a Dispenser Distribution Sys-
tem 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)
