Introduction

201520R6 7

The cycle begins with a wash fill. The water

temperature is determined by the temperature selector.

While water fills the washtub, a column of air is

trapped in a pressure bulb and hose. The air pressure

continues to increase as the washtub fills with water

until it is great enough to activate the pressure switch.

The pressure switch then causes the wash fill to stop

andwash agitation to begin.However,the loading door

must be closed for the washer to agitate or spin.

The washer uses a reversing type motor, a special drive

belt and an idler assembly. The idler assembly applies

tension to the outside of the drive belt.

During agitation, the motor runs in the

counterclockwise direction. The spring tension on the

idler pulley applies the tension required to reduce the

slack on the drive belt and maintain maximum belt to

motor pulley contact. This eliminates belt slippage and

ensures an efficient wash action, even with extra large

loads.

The belt drives the transmission drive pulley in the

counterclockwise direction. The pulley drives the helix

which is splined to the input shaft of the transmission.

This causes the input shaft to turn inside of a roller

clutch which is pressed into the transmission cover.

This roller clutch acts as a bearing in the

counterclockwise direction allowing the transmission

gears to operate. The transmission’s rack and pinion

gear design produces a 210 degree agitation stroke at

the output shaft of the transmission which drives the

agitator.Thebrake assembly remains locked during the

agitation mode since no pressure is applied to it by the

transmission drive pulley.

After the wash agitation is completed, the timer

advances into the first spin. During spin, the motor

reverses turning in the clockwise direction to spin the

water out of the washtub. The combination of water,

washtub and loadweightcause the drive belt tension on

the idler side of the belt to overtake the idler spring

pressure allowing the belt to become slack on the

opposite side. This reduces the belt to pulley contact

and allows slipping between the belt and pulley.

As water is removed by the pump and the momentum

of the washtub increases, the idler spring tension

gradually overcomes the belt tension removing the belt

slack. This eventually increases the belt to pulley

contact until maximum spin speed is achieved.

The drive pulley turns clockwise riding upthe ramps of

the helix, exerting pressure on the brake and forcing it

to release from brake pads. The helix drives the input

shaftofthetransmission,andwhentheinputshaftturns

in the clockwise direction the roller clutch locks onto

the shaft causing the entire transmission assembly to

turn. None of the gears in the transmission are

operatingat this time.Thehubofthe washtub is splined

to the transmission tube and rotates with the

transmission assembly. The centrifugal force created

by the spinning washtub causes water to be extracted

from the clothes.

Water is introduced during the first spin to “SPRAY”

the garments and remove suds from them. The initial

spin is followed by rinse agitation to rinse away any

detergent residue. The washer fills and then agitates

like the wash portion of the cycle. Following rinse

agitation, a final spin extracts the rinse water from the

clothes preparing them for the dryer.
