INSTALLATION CONSIDERATIONS

1. Carefully follow the installation instructions supplied with the washer for information related to

your product.

KEY POINTS TO REMEMBER:

2. Remove the shipping strap as follows:

a. Carefully read, then remove the yellow label securing the power supply cord to the back of

the washer. (Fig. 1-1)

b. With the washer upright, pull the yellow shipping strap completely out of the back of the

washer. Be sure both cotter pins come out of the washer. Note that the power supply cord

plug will still be attached to the yellow shipping strap. (Fig. 1-2)

c. Firmly pull on the end of the yellow shipping strap that is attached to the bottom of the back

of the washer. (Fig. 1-3) This will release the self-leveling leg mechanism.

Fig. 1-2

Fig. 1-3

Fig. 1-1

NOTE:To prevent the two (2) shipping pins from falling on the floor, two (2) plastic

holders are attached to the base. (Fig. 1-4) When the cotter pins are removed,

the shipping pins fall into these holders. These pins may be left in the

holder cups. (Fig. 1-4, INSET) They will not interfere with the operation of the

washer.

Section One - Part B

THEORY OF OPERATION

All washers perform essentially the same four functions. They fill with water, agitate, drain the water

and spin the water out of the clothing.

1. Before the washer can fill, the customer makes selections that:

•

Control the length of the wash cycle by turning the timer control knob

Control the temperature of the wash and rinse water by setting the water temperature switch.

The water temperature switch is identified by the dotted box in Fig. 2-2. The wash temp switch

chart indicates three possible switches, depending on the model washer being used. The switch

letters in the chart, H W and C are the possible water temperature selections, Hot , Warm and

Cold. The first letter is the wash temperature, the second letter is the rinse temperature.

Control the amount of water required for the amount of clothing by setting the water level or

pressure switch.

•

2. Once the selections are made, a series of switches are closed in the timer and water temperature

switch. If, for example, the customer selects the beginning of the REGULAR cycle, increment 4,

and a WARM wash and COLD rinse, the following switches would be closed.

Fig. 2-2

Fig. 2-3

Download from Www.Somanuals.com. All Manuals Search And Download.

The water level switch is set to move from the

EMPTY position to the FULL position depend-

ing on how much tension is set on the switch

diaphragm.

3. When the customer pulls the timer knob out,

voltage is supplied to the hot and/or cold wa-

ter inlet solenoids. In the example above, both

solenoids are energized to allow water to fill

the tub.

Typical Water

Level Switch

Fig. 2-4

4. As the water level rises in the tub, it causes

an increase in air pressure in the air dome

assembly mounted to the side of the tub. A

hose between the air dome and the water level

switch transfers this air pressure against the

diaphragm in the water level switch, causing

electrical contacts to move from V to P,

(EMPTY position), to V to T, (FULL position).

The washer stops filling and the water level

switch is providing voltage to the timer motor

and the drive motor to begin agitation.

1. Once there is power to the timer motor, the timer will start to advance. The drive motor will also

begin to turn counterclockwise in the agitation direction. The direction of current through the dirve

motor start winding will determine the direction the drive motor runs. In the agitation mode, con-

tacts 7 are closed, causing current to flow in the start winding opposite the flow in the run winding.

Fig. 2-9

2. The motor is coupled directly to the transmis-

sion and will cause the transmission shaft to

turn in the agitate direction. The agitator is

mounted directly to the transmission shaft and

is driven back and forth to provide agitation.

Pump

3. The water pump is mounted directly to the

motor and will also turn in the agitate direc-

tion. At this point the pump is running in re-

verse, so water does not leave the tub.

Motor

Fig. 2-10

4. During the agitation cycle, the wash water is

being pulled through a basket mounted lint

filter, (if equpped), by pumping vanes molded

into the underside of the agitator. Due to the

shape of the filter, lint is captured on the filter

fins.

5. Also, during the agitation cycle, the transmis-

sion is being set up for neutral drain to pro-

vide a pump-out prior to going into spin.

6. Once the timer has advanced to the end of

the wash cycle, contacts open in the timer

causing the drive motor to stop.

1. The timer advances to the next step in the process, which is the drain cycle. This time, contacts 14

in the timer are closed, energizing the drive motor to run in a clockwise direction. The current flow

in the start winding is the same as that in the run winding.

Fig. 2-13

2. The drive motor now turns the pump in the clockwise or drain direction causing the pump to drain

the dirty water out of the tub through the drain hose.

3. The weight of the water being pulled over the lint filter flushes the lint from the filter and out the

drain hose with the dirty water.

Fig. 2-14

4. After a two-minute drain, the timer contacts open momentarily, stopping the drive motor. This

momentary pause causes the transmission to reset itself for the spin cycle.

1. After the motor restarts, in the same clockwise direction, the transmission is reset for the spin

mode and the spin pinion begins to turn.

2. A clutch housing is mounted directly to the transmission spin pinion and begins to turn as well.

3. Inside the clutch housing is a clutch lining that is turned by the clutch housing by friction. The clutch

lining is an almost complete circular band that is cushioned with a spring to allow the clutch to slip

as the basket is coming up to speed. This slip prevents high torque loads on the motor and allows

the motor to bring this heavy load up to speed without overloading.

4. The clutch lining is designed to contact the basket drive brake cam which releases the basket

drive brakes during the spin cycle, allowing the basket drive to turn freely.

5. The basket drive is connected to the basket with a drive block and nut. The turning basket drive

causes the basket to begin to spin.

6. As the basket gets up to its full spin speed, the clutch slippage is gradually reduced until the clutch,

basket drive and basket are being driven as if they were one unit.

The motor coupler serves as a cushion

between the motor and gearcase and a

safeguard to protect the motor in the

event of a binding of the gearcase.

The coupler ends can be removed by

prying the outer pieces from the motor

and gearcase. If service to any of the

pieces is required, they must all be re-

placed.

THEORY OF OPERATION

GENERAL INFORMATION

Start Up

Whenever the washer power cord is plugged into an electrical supply, the electronic control will be

energized. At this time, the microcontroller will be permanently on-line waiting for user input.

Fig. 1

Cycle/Status Indicators

There are three red status indicator Light Emitting Diodes (LED) on the console:

• Wash

• Rinse

• Final Spin

A blinking indicator is the signal that the washer is in Pause Mode. If all lights are off, the washer is OFF.

Pause Mode

The Pause Mode can be used to interrupt machine cycles at any time. To initiate a Pause Mode,

press the START/PAUSE button on the console panel. Any Cycle/Status indicator that was lit at the

time the START/PAUSE button was pressed will flash every ½ second until the Pause Mode is termi-

nated. To terminate or exit the Pause Mode press the START/PAUSE button a second time. If the

washer remains in Pause Mode for more than two hours the microcontroller discontinues the program

and turns off all the LEDs.

Soak Mode

The Soak Mode suspends the wash cycle for a timed interval before completion of the cycle. In order

to alert the user that the washing process has not finished, the Wash indicator LED remains lit during

soak. If the Pause button is pressed while in Soak Mode, the Wash LED will blink.

Long Fill Time

If the user selected water level has not been reached after 30 minutes the microcontroller will discon-

tinue the program and turn the washer off.

Long Drain Time

If the water level switch does not detect a low water level condition after 14 minutes of Drain, the

microcontroller will discontinue the program and turn the washer off. NORMAL DRAIN TIME IS

APPROXIMATELY 5 MINUTES.

Cycle Select Knob

The Cycle Select Knob must be turned to the OFF position to terminate the current wash cycle and

begin a new one.

S.I.S. (Sub-Interval Spin)

Sub-Interval Spin (S.I.S.) is a series of short spin times initiated during the first 120 seconds of the

cotton/regular spin cycles and throughout all of the permanent press and delicate spin cycles. The

S.I.S. is designed to help the washer break up soap suds for easier water removal during drain.

(Table 1)

Water Level Control

The load setting or water level control is determined through the use of an electromechanical pressure

switch which provides a 120VAC signal to the microcontroller. The microcontroller reads the signal

from the water level pressure switch during fill, agitate or drain functions only. Water level changes

during any other function will not be initiated by the control system.

Adjusting the water level control to a higher level during the agitate function will cause the washing

action to stop (no agitation) and the appropriate water valves will be turned on until the newly required

water level is met.

Adjusting the water level control to a lower level during the agitate function will not take affect until the

next water fill takes place. (i.e. No water will be pumped out during agitation.) NOTE: Do not adjust the

screw on the pressure switch.

Water Temperature Switch

The water temperature switch can select up to four predetermined Wash and Rinse water tempera-

ture combinations.

TEMPERATURE SELECTOR

Position No.

Temperature

CC = Cold Wash and Cold Rinse

WC = Warm Wash and Cold Rinse

HC = Hot Wash and Cold Rinse

WW = Warm Wash and Warm Rinse

Table 3

* Available with 4 temperature option only.

Rinse water temperatures are limited to warm and cold to improve energy efficiency.

Start/Pause Button

The START/PAUSE button is pressed to start the selected washing action and to pause the machine

during any function. The first time the START/PAUSE button is pressed after a selection is made

initiates the washer operation.

The second time the START/PAUSE button is pushed after the washer has begun running will put the

machine in a Pause Mode. All machine functions will stop and cycle timing will not resume until the

START/PAUSE button is again pressed. The “Paused” mode will be indicated by the blinking of any

one of the LEDs. After 2 hours in the PAUSE MODE, washer will turn off.

Features

A.Bleach Dispenser - Located under the lid in the rear left corner. Pour liquid bleach into this dis-

penser. The washer dilutes and dispenses the bleach during the wash cycle.

B.Liquid Fabric Softener Dispenser - Located at the top of the agitator. Liquid fabric softener is

dispensed at the beginning of the rinse cycle. Fabric softener will only dispense if spin reaches full

speed. Rinse the fabric softener cup under hot water when residue builds up.

C.Lint Filter - Pull the liquid fabric softener dispenser up from the center of the agitator. To clean the

lint filter, wipe around the inner surface with a finger.

CYCLE FUNCTIONS

First Step

With the Cycle Selector Knob in the OFF position, turn the Water Level and Wash/Rinse Water Tem-

perature knobs to the desired settings.

Fill Cycle

NOTE: See FILL Strip Circuit on page 67.

Turn the Cycle Selector Knob to the desired wash cycle. The washer will begin to fill. When the water

has reached the predetermined level the water level switch will break power to the water fill valves and

the fill valves will turn off. The water pressure switch circuit remains active during the wash cycle to

maintain the proper water level in the tub. A high water level fill will be approximately 17 gal. (64.6 L).

Wash (Agitate) Cycle

NOTE: See AGITATE Strip Circuit on page 67.

Wash agitation is acheived by reversing the direction of the drive motor. The electronic control board

will initiate a four part control cycle to the drive motor. Step 1 will apply power to the drive motor in one

direction for a predetermined length of time (as determined by the washing action chosen by the cycle

selector switch). In step 2 the power is turned off for a period of time. Step 3 again powers the drive

motor, but in the opposite direction, for a period of time. Step 4 again turns the power to the motor off.

This cycle is repeated for the duration of the WASH/RINSE cycle. The tables below show the duration

of the agitate cycle for Normal and Gentle Wash.

The HANDWASH cycle adds one more time variable. Normal agitation will occur for 5 seconds

followed by 10 seconds of no agitation. This will continue until the WASH/RINSE cycle is completed.

Drain Cycle

NOTE: See DRAIN Strip Circuit on page 68.

The electronic control board will apply power to the drain pump during the drain cycle. The pump will

remove the water from the tub into an appropriate drain. At the time that the drain pump is activated

the control board also energizes the brake solenoid, releasing the basket to spin.

Download from Www.Somanuals.com. All Manuals Search And Download.

Spin Cycle

NOTE: See SPIN Strip Circuit on page 68.

The drain pump and brake solenoid are energized at the beginning of the Spin Cycle. The energized

brake solenoid releases the brake and engages the splutch.

For the first 120 seconds of the Spin Cycle the electronic control board sequentially cycles the drive

motor on and off to allow the basket to slowly build up speed. This sub-interval timing loop allows the

water and suds to move through the drain holes in the basket and flow down the outside of the basket.

This draining action keeps the suds from building up between the basket and the tub. If this did not

occur, the suds build up could cause the motor to go into thermal overload and shorten its life.

The Splutch Assembly

The splutch slider has teeth around the bottom hub that mate with the teeth in the pulley. The engag-

ing and disengaging of these teeth changes the drive motor from operating the agitator or spinning the

tub. (Fig. 3)

The hub of the slider is grooved to fit over the lower splined end of

the spin tube on the gearcase assembly. The upper portion of the

spin tube is connected directly to the basket. As long as the slider

is engaged with the splutch pulley the basket will rotate.

The cam ring controls the movement of the slider up or down. As

the cam ring rotates, the tabs on the bottom slide up and down on

mating tabs in the splutch housing. This up and down movement

of the cam ring controls the movement of the slider. A spring main-

tains pressure between the two sets of tabs.

The rotation of the cam ring is controlled by the brake solenoid and

the brake arm assembly. This assembly also has a brake band

which is wrapped around a rotor on the end of the spin tube. When

the solenoid is energized:

The brake arm rotates to loosen the brake band around

the rotor.

Fig. 3

The cam ring rotates to lower the slider.

The Splutch Assembly During Wash/Agitate

When a Wash/Agitate cycle occurs, the agitator which is connected to the shaft inside the spin tube, is

rotated by the drive motor and the splutch pulley. At this time the brake solenoid is not energized.

This leaves the slider disengaged from the pulley and the brake band in tight against the rotor. This

keeps the spin tube from moving. (Fig. 4-A)

The Splutch Assembly During Spin

When a Spin cycle occurs, the brake solenoid is energized causing the slider to drop onto the pulley

teeth. The brake band is loosened from around the rotor releasing the spin tube. The basket and

agitator can now be directly driven by the drive motor and spin. (Fig. 4-B)

Fig. 4

The Gearcase Assembly

The gearcase has two separate shafts, one inside the other. The inner shaft is splined and is driven

by the drive motor through the splutch pulley and drive belt. The agitator slides over the top of the

splined inner shaft and rotates when the drive motor operates.

The outer shaft or spin tube is connected to the rotor and operates independently of the inner shaft.

Four planetary gears located inside the gearcase reduce the speed of the spin tube to a 5:1 ratio.

These gears are driven by a central gear connected to a shaft emerging from the splutch assembly.

THEORY OF OPERATION

THEORY OF DRYING

To understand how a dryer can dry laundry, it is necessary to understand how the process of drying,

or evaporation, can be accelerated.

The goal of drying is to remove the water that has saturated the laundry during washing. During the

SPIN CYCLE of the washer, much of the water is extracted while it is still in its liquid form. To remove

the remaining water, it is necessary to convert the liquid water into water vapor. This process of

changing a liquid to a vapor is called evaporation. Under normal conditions, the process of evapora-

tion is very slow.

As an example, water in a glass set on a table at room temperature will take days to completely evapo-

rate. A damp towel from a shower, balled up and placed in a clothes hamper will probably still be damp

several days later when it is removed.

However, by controlling the conditions during the evaporation process, the rate of evaporation can be

accelerated.

BY APPLYING HEAT

The process of evaporation can be accelerated by

applying heat. As shown in Figure 3-1, when a pan

of water is heated on a stove top, the water rapidly

boils (evaporates from liquid to vapor.)

Fig. 3-1

BY MOVING THE SURROUNDING AIR

The process of evaporation can be accelerated by

moving the surrounding air. During evaporation,

the air immediately surrounding the surface of

the liquid water can become saturated with water

vapor. At this point the air cannot accept any more

evaporating water. Moving the saturated air away

from the surface of the liquid water and replacing

it with air that can still accept water vapor can ac-

celerate the rate of evaporation.

Fig. 3-2

As an example, clothing hung out to dry on a

clothes line will dry faster when there is a breeze,

and you will feel cooler (a sign of evaporation) when

you stand in front of a fan on a hot day. (Fig. 3-2)

BY INCREASING THE SURFACE AREA OF THE LIQUID

The process of evaporation can be accelerated by

increasing the surface area of the liquid. As show

in Figure 3-3, the water in a glass can be poured

out onto the floor. Spread out in a puddle, the water

will likely evaporate in just a short amount of time.

Fig. 3-3

Download from Www.Somanuals.com. All Manuals Search And Download.

MECHANICAL SYSTEMS TO ACCELERATE DRYING

The mechanical systems in a dryer control these same three conditions to accelerate the evaporation

of liquid water remaining in laundry. Within the dryer drum, the dryer:

A) Applies Heat to the Liquid Water

B) Provides Movement of Air over the Water

C) Increases the Surface Exposure of the Water

Efficient drying of the laundry is the result.

In a dryer, air is heated by either an electric element or a gas burner. The heated air is drawn into the

drum and passed over the laundry. To prevent the heated air from becoming completely saturated

with water vapor, a fan continually pulls the moisture-laden air from the drum and exhausts it outside.

Relatively dry heated air is continually drawn into the drum to replace the moisture-laden air being

exhausted. (Fig. 3-4)

When you understand how a dryer works, you can understand why it is important that the dryer be

properly exhausted to the outside. If the moisture-laden air was vented back into the room where the

dryer was located, the air in the room would quickly become saturated. This same air would be continu-

ously drawn back into the dryer, heated and passed over the wet laundry. The drying time would be

greatly increased.

Fig. 3-4

Air system is similar in gas and electric dryers.

Gas Dryer shown.

TO MAINTAIN DRYING EFFICIENCY

• The Dryer Must Be Correctly Installed • The Laundry Must Be Properly Sorted

(Heavy items dried with light weight

garments can develop over-drying and

• The Dryer Must Be Properly Vented

• The Air Flow Must Be Unrestricted

(Clean Lint Screen)

under-drying in the same load.)

• The Washer Must Extract As Much Water

As Possible During the SPIN CYCLE

• The Dryer Must Not Be Overloaded

Servicing Components on the Rear of the Bulkhead

There are two panels on the back of the dryer that allow access to components at the rear of the

bulkhead.

The smaller panel covers the electrical connections for the dryer.

On Gas Dryers the three prong grounded 120VAC power cord is connected at this location.

On Electric Dryers the 240VAC terminal block is located under the small access panel.

The large louvered back panel covers the intake and exhaust system. On Gas Dryers the louvers in

this panel provide auxiliary air for the gas burner.

Electric Heater Element

On electric dryers the electric heater element is contained in a housing attached to the lower portion of

the heater box.

To remove the heater element:

Disconnect the wire leads from the high-limit thermostat and the heater element terminals.

Fig. 4-1

TIMER CONTROL

Electronic Dry-Miser

This cycle can be used for most loads. Drying time varies according to type of fabric, size of load and

dryness setting.

•

Set the Cycle Selector Control to the desired dryness.

Dryness is determined by an electronic moisture sensor system that “feels” the amount of

moisture in the clothes as they pass over a moisture sensor mounted on the grille assembly

at the front of the drum area. When the selected dryness is reached the dryer goes into a

timed COOL DOWN period of approximately 10 minutes.

•

The End-of-Cycle signal sounds once the cycle is complete.

The End-of-cycle signal can be turned OFF by pressing the Cycle Signal OFF pad on the

Clean Touch console.

•

The Finish Guard option will tumble the clothes without heat for about 15 seconds every five

minutes until the door is opened and the clothes removed.

The Finish Guard option can be turned OFF by pressing the Finish Guard OFF pad on the

Clean Touch console.

Timed Dry Cycle

This cycle will provide up to 80 minutes of heated drying time.

•

The heating cycle is followed by approximately 10 minutes of COOL DOWN.

The End-of-Cycle signal sounds once the cycle is complete.

The End-of-cycle signal can be turned OFF by pressing the Cycle Signal OFF pad on the

Clean Touch console.

•

The Tumble Press portion of the Timed Dry Cycle is designed to provide about 15 minutes of

HEATED TUMBLING followed by 10 minutes of COOL DOWN.

Download from Www.Somanuals.com. All Manuals Search And Download.

Fluff Air Cycle

The Fluff Air Cycle provides up to 30 minutes of unheated drying time.

CLEAN TOUCH CONTROL PAD

The clean touch control pad provides push button control of the following operations:

TEMPERATURE SELECTION - Four levels of temperature ranging from Extra Low to High.

FINISH GUARD - Allows this option to be turned On or OFF.

CYCLE SIGNAL - Allows this option to be turned On or OFF.

PUSH-TO-START KNOB

This knob must be pushed to start the dryer. The door must be closed for the dryer to operate. If the

door is opened during any drying cycle, the dryer will not operate again until the Push-to-Start knob is

pushed again.

“C” VERSION ELECTRONIC DRYER CONTROL

The “C” version dryer control system consists of an electronic control board located in the console

area and a moisture sensor attached to the lint screen grille inside the dryer drum. The dryer control

system measures the resistance across the moisture sensor during the automatic dry cycle. The

electronic control board turns power to the timer motor on and off based on input from the moisture

sensor.

Theory of Operation

When a cycle is selected, Timer Switch 1 will be closed. This applies 120VAC through the orange/

white wire to the electronic control board. Timer Switch 0 will be open if the selected cycle is not a

timed dry cycle, so there is no alternate path for current flow through the timer motor. (Fig. 4-2)

W/BK

T/W

Fig. 4-2

Download from Www.Somanuals.com. All Manuals Search And Download.

The electronic control looks at the input from the moisture sensor to see if the clothes are wet or dry.

The moisture sensor will show continuity (short) if the clothes are wet and show NO continuity (open)

if the clothes are dry.

If the clothes are wet, the Triac on the electronic control board will block power to the timer motor, and

the timer motor will not advance.

If the clothes are dry or there are no clothes in the dryer the Triac on the electronic control board will

allow power to flow to the timer motor causing it to advance.

During the last 10 minutes of the Regular Cycle, (the last 15 minutes of the Permanent Press Cycle)

and any Timed Dry Cycle, Timer Switch 0 will be closed. This will allow the timer motor to advance

regardless of the condition at the moisture sensor. Timer Switch 0 bypasses the electronic control.

Heated Air Circulation

Room temperature air (shown as white arrows in

Fig. 4-4) enters the lower portion of the dryer cabi-

net underneath the toe panel and is drawn through

the heating system (electric heating element or

gas burner assembly).

Heated air (shown as dark grey arrows in

Fig. 4-4) is then drawn up the heat duct mounted

to the rear bulkhead and into the dryer drum.

As the heated air circulates in the drum it picks

up moisture (shown by the lighter grey arrows in

Fig. 4-4).

Moisture ladened air it then drawn down through

the lint filter, through the blower and out through

the exhaust duct to be vented out of the dryer.

Venting can be accomplished straight through the

back of the dryer, through either side of the dryer

or down through the bottom of the dryer. (Fig. 4-4)

Cycle Control Knob

The washer features ten different wash cycles which are identified around the large cycle control knob

at the left side of the control panel.

To select a wash cycle:

Push the cycle control knob “IN”. This will allow the knob to be turned clockwise to the desired

cycle setting.

When the cycle control knob is pulled “OUT” the washer will begin to OPERATE.

When the Cycle Control Knob is set to a specific wash setting and pulled out, the following will take

place in a pre-determined sequence depending on the wash cycle chosen:

Wash Sequence

The washer begins to fill to the selected load size.

When the water level has reached the selected load size the washer will immediately

begin to agitate. (Agitation will occur with the washer lid open or closed.)

Following agitation all the water will drain from the tub. No agitation occurs.

NOTE:The permanent Press Cycle partially drains, fills, agitates briefly and fully

drains.

The fourth action during a wash cycle is spin, during which excess water is removed from the

fabrics. (Spin will only occur with the washer lid closed.)

Rinse Sequence

The washer will fill to the pre-deterimed load size.

When the water level has reached the selected load size the washer will immediately

begin to agitate. (Agitation will occur with the washer lid open or closed.)

Following agitation the water will drain from the tub. No agitation occurs.

The washer will spin while clean water is sprayed into the basket. There are two (2) 15 second

clean water sprays during the final spin.

Temperature Selector

The temperature Selector allows for four (4) different water temperature settings for the wash and

rinse cycles. The water temperature can be matched to the types of fabrics and soils being washed.

Water Level Selector

The Water Selector allows for five (5) water levels to be selected depending on the size of the wash

load. To change the water level after the washer has started, move the selector to the desired setting.
