THEORY OF OPERATION
INTRODUCTION
The HFand HEt Front-Loading
Automatic Washers present a number of new features and operating
characteristics quite different from previous models. In addition to the introduction of front-loading
operation, the HF and HEt contain a number of unique operating features designed to increase
clothes cleaning ability while offering very high water and energy conservation.
Water System
The HFandHFt 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
signalfrom 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 tempera-
ture can be increased through the use of a heating element located in the bottom of the tub, (HFt model
o n l y ) .
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.
Dispenser Distribution System
All wash and rinse water is introduced into the wash tub through a Dispenser Distribution
System lo-
cated in the top left corner of the washer. The system consists of a motor that turns a cam gear. The cam
follower willdivert the incoming water to one or more ol the follow water inlet modes:
. Detergent Dispensing
. Bleach Dispensing
. Fabric Softener Dispensing
. Rinse Dispensing (no additives)
