PRODUCT OPERATION

THEORY OF OPERATION

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.

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)

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