THEORY OF OPERA TION

INTRODUCTION

The

and

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 washers

contain 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 tempera-

ture can be increased through the use of a heating element located in the bottom of the tub, (GHW9200

model only).

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. The flowmeter is

also used to introduce additional water into the tub for higher

water levels, based on cycle requirements. Refer to page 6-

12 for more details.

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 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)
