Top Load Automatic Washers
T
he automatic washer is a complex electromechanical machine, and Figure 18-1 is usedas an example only. The actual construction and features of the washer you are
servicing might vary, depending on brand and model. The automatic washer
performs various cycles to clean clothes. There are times when a washer fails to operate
properly. Dont let its complexity intimidate you. This chapter will provide the basics
needed to diagnose and repair the washing machine. On electronic models, you may need
to have the service manual and the technical data sheet (located inside the control panel)
present to perform the diagnostic test/service modes.
Principles of Operation
The clothes are placed evenly into the washer basket, making sure that the washer is not
overloaded and that the proper cycle is selected. The user then adds detergent to the washer
(see the use and care instructions), and then the user activates the washer through the timer.
The internal switches of the timer distribute the electricity to activate the other components
in the washing machine during a given time period, designated by the internal cam of the
timer.
The water enters the tub through the water fill hoses, the water inlet valve, and water
inlet hose. Hot, warm, or cold water is selected by the user via the water temperature selector
switch, located on the console panel. On some models, the water temperature selection is
controlled by the timer.
The amount of water that fills the tub is controlled by the water level control (pressure
switch). The water level control offers a choice of water levels, depending on the amount of
clothing being washed. As the water level rises in the tub, it forces air through the air dome
and up the plastic tube to the water level control. The pressure that is exerted on the water
level controls diaphragm will trip the water level switch from empty to full, supplying
electricity to the washer drive motor, and thus operating the transmission.

direct drive, depending upon the model. Agitation is accomplished by the agitator, which
is located in the center of the basket and which is driven by the transmission/gearbox. The
agitator turns clockwise and counterclockwise, creating a water motion that moves the
clothes within the basket.
When the washer goes into the drain mode, the agitator will stop agitating, and the
water leaves the bottom of the tub through the water pump, to be pumped into the drain.
The water pump may operate by belt drive, by direct motor drive, or by an electric motor.
A final deep rinse cycle (the tub fills to the selected water level and begins to agitate)
will be introduced to wash off any remaining residue of soap or dirt.
The timer will now select the spin cycle, and the washer will then go into the spin mode.
In the spin mode, the washer spins the clothes, removing most of the water from the clothing
by centrifugal force. Some models use brief sprays of water to remove any residue of soap or
dirt remaining on the clothes in the spin cycle.

507Functions and Cycles
The removal of soil from clothing and fabrics is accomplished by a combination of
mechanical and chemical processes:
Mechanical process Soil is removed by agitating and by forcing the detergentthrough the clothing.
Chemical process The detergent used will dissolve and loosen the soil in theclothing. As the washing machine operates through its cycles, it is aided by hot,
soft water, which increases the chemical processes of the detergent being used.
Top load washing machines perform four basic functions, which are modified and put
together in different ways to create the various cycles. The four functions are:
Fill
Agitate
Drain
SpinSafety First
Any person who cannot use basic tools or follow written instructions should
not attemptto install, maintain, or repair any top load automatic washers. Any improper installation,
preventive maintenance, or repairs could create a risk of personal injury or property
damage.
If you do not fully understand the installation, preventive maintenance, or repair
procedures in this chapter, or if you doubt your ability to complete the task on the top
load automatic washer, please call your service manager.
The following precautions should also be followed:
Never bypass or disconnect any part or device (originally designed into the washer)as a temporary repair.
Always reconnect all ground wires, and be sure that they are secure.
Be careful of moving parts and sharp edges.Before continuing, take a moment to refresh your memory of the safety procedures in
Chapter 2.
Automatic Washers in General
Much of the troubleshooting information in this chapter covers top load automatic washers
in general, rather than specific models, in order to present a broad overview of service
techniques. The pictures and illustrations that are used in this chapter are for demonstration
purposes only, to clarify the description of how to service washing machines, and in no way
reflect a particular brands reliability.

P a r t V I : A p p l i a n c e S e r v i c e , I n s t a l l a t i o n , a n d P r e v e n t i v e M a i n t e n a n c e P r o c e d u r e sLocation and Installation of the Top Load Automatic Washer
The following are some general principles that should be followed when performing the
installation of a top load washing machine:
Locate the washing machine where there is easy access to existing drain, water, andelectrical lines.
Be sure you observe all local codes and ordinances for the electrical and plumbingconnections.
The washing machine should be installed and leveled on a firm floor to minimizevibration during operation.
Do not install the washing machine in an area where the temperature might bebelow freezing.
To reduce the risk of a fire, never install a washing machine on any type of carpet.
Always follow the installation instructions that are provided with every newwashing machine model purchased.
Common Installation Problems
Top load automatic washer installations are not complicated. As a service technician, you
will come across a top load washer that has not been installed according to the
manufacturers installation instructions. The following sections describe some of the
problems that you might run into and how to solve them.
When you arrive at a service call and the consumer tells you that the washer is full of
water and it will not drain out, check for the following:
The drain hose is kinked.
The drain hose has a blockage.
The drainpipe might be too small, not allowing for proper venting. The drainpipemust be a minimum of 1½ inches in diameter.
The drainpipe and the drain hose were installed over six feet above the floor.If the consumer tells you the washer will not fill up with water or very little water is
entering the washer, check the following:
The water faucets were never turned on or they were turned on only a little bit.
There is a blockage in the water inlet screen. The consumer did not flush out thewater lines before installing the hoses on the washer.
When the washer is filling with water, the water is siphoning out through the drainline. The drainpipe is too low or the wrong size diameter. You might have to install
a siphon break kit at the end of the drain hose.
When you arrive at the service call, you notice water on the floor. Check the following:
The water hoses to the water inlet valve
The water faucet might be leakingPART VI
C h a p t e r 1 8 : To p L o a d A u t o m a t i c W a s h e r s
509
The drain hose is not connected properly to the washer
The drain hose comes out of the drainpipe
The drainpipe might have a blockage
The household drain cannot handle the capacity of the discharge waterWhen the washer goes into the spin cycle, it will begin to vibrate and walk across the
floor. Check the following:
The feet or leveling legs on the washer are not set properly, causing the washer toteeter-totter.
Is the washer level?
Is the floor level?
Check and see if the packing and shipping straps have been removed. Read theinstallation instructions on removing the packing straps.
Are the clothes distributed evenly within the tub?Water Supply
The water supply for an automatic top load washer should have a hot and cold faucet
located within five to seven feet of the washer. The faucets should be a 3/4-inch threaded
type to accept the fill hose connection.
The water pressure must be between 25 and 125 pounds per square inch for the washer
to operate properly. The water coming out of the fill hoses should be equal in both pressure
and in the volume of water to prevent unacceptable water temperature changes when
entering and filling the washer.
The hot water supply to the washer should be between 130 and 150 degrees Fahrenheit. If
the hot water temperature is below 70 degrees Fahrenheit, the clothes being washed will not
clean properly and the detergent will not dissolve properly. You can check the temperature of
the hot water by operating the washer in the fill mode with the water temperature setting on
hot. Let the water run until it is as hot as possible, and then insert a thermometer into the
stream of water. If the thermometer reading is below 130 degrees Fahrenheit, you will have to
raise the water heater thermostat setting. The cold water temperature should be between 70
and 100 degrees Fahrenheit. When the washer is in its rinse stage, the cold water will
prevent wrinkles from setting into the fabrics. Some fabric manufacturers require that their
fabrics be washed in cold water, both to prevent shrinkage and to eliminate the possibility
of destroying the fabric. When the user selects the warm fill, the temperature of the water
should be 100 degrees Fahrenheit.
It is recommended that the consumer read the use and care manual before performing a
wash. Most use and care manuals have a water temperature guide to assist the user in the
proper selection of the water temperature.
Drain Requirements
The drain to which the washers drain hose is connected must be able to accept at least a
20- to 30-gallon-per-minute flow in order to remove the water from the tub. The standpipe
should be at least 32 inches high and not exceed 60 inches in height. The internal diameter

the drain hose and thus prevent the suction from siphoning the water out of the tub during
the wash cycle.
Detergent
The kind and amount of detergent that is used is an important part of getting clothes clean.
Some top load automatic washer models are designed to use HE (high efficiency) detergent
while other models use regular detergent. Different brands of detergent contain different
amounts of phosphorous, which works to soften the water and to boost the cleaning action.
If the water is hard, you might need to recommend a detergent with a higher phosphorous
content. If the water is soft, the user can use a low-phosphorous detergent.
Some areas restrict the phosphate content to 8 percent or less. This means that the user
will have to increase the amount of detergent used in those areas where the water is hard.
This is done by adding a certain extra amount of detergent manually to the wash cycle.
It is recommended that the consumer read the use and care manual before performing a
wash. Most use and care manuals have a detergent guide to assist the user in the recommended
amount of detergent to use.
Water hardness is measured in grains:
0 to 3 grains: soft water
4 to 9 grains: medium-hard water
10 to 15 grains: hard water
Over 15 grains: very hard waterIf you do not know the hardness of the water supply, contact the local water department.
Step-by-Step Troubleshooting by Symptom Diagnosis
In the course of servicing an appliance, dont overlook the simple things that might be causing
the problem. Step-by-step troubleshooting by symptom diagnosis is based on diagnosing
malfunctions, with their possible causes arranged into categories relating to the operation of

Common Washability Problems
If there are no mechanical problems with the washers operation and the complaints are
that the washer does not clean the clothes properly, you have a washability problem. The
next step should be to look at the cause that best describes the problem that the customer is
experiencing with the washer. Then proceed to correct the problem. If necessary, instruct the
user how to get better results from the automatic washer.
Stains on the Clothing
Stains on clothing can be caused by a number of different things. As the servicer, you will
have to determine if it is caused by the washers components or from an external source.
PART VI
C h a p t e r 1 8 : To p L o a d A u t o m a t i c W a s h e r s
515Many stains are blamed on leaking transmissions. This type of problem is related to the
increasing use of synthetic fabrics and to the poor washing practices of the user. Many of
these stains consist of cooking oil or grease and are not visible when they first occur during
cooking or eating. The oil that is embedded in the clothing acts like glue, attracting dirt
from the wash water. When the wash cycle is completed, the clothes come out dirty and
spotted. If the transmission oil leaked into the wash water, there will be stains on all of the
clothes in a random pattern. The color of transmission oil embedded into the clothing is
usually a brownish-yellow stain. Transmission oil cannot be washed out of the clothes; a
solvent is required to remove the stains.
The following are some stain-removal rules for clothing in general:
Stains are easier to remove when they first appear on the clothing. If the stains areold, they might never come out of the clothing.
Before attempting to remove any stain, you must know: what type of stain, whatkind of fabric, and how old is the stain?
Use only cold or warm water to remove stains. Hot water will set the stainpermanently into the fabric.
When bleach is recommended for the removal of the stain, use a bleach that is safefor the fabric. When using a chlorine bleach, always dilute it with water to prevent
the bleach from destroying the fibers.
Always test stain remover products on a hidden corner of the garment to see if thecolor remains in the fabric.
When preparing to remove the stain from the fabric, face the stained area down ona paper towel or a white cloth. Then apply the stain remover to the back of the stain
so that the stain will be forced off the fabric, instead of through the fabric.
Some protein stains can be removed with an enzyme pre-soak or with meat tenderizer.
When using dry-cleaning solvents, always use them in a well-ventilated room, awayfrom flames and sources of ignition to prevent personal injury.
Alcoholic beverage stains turn brown the longer they stay on the fabric. As soon asthe stain appears on the fabric, start treating the stain immediately. Wash or soak the
stain in cold water, and then wash the garment.
To remove blood stains, rinse or soak the garment in cold water with an enzymepre-soak product. You can use diluted chlorine bleach on white fabrics, if necessary.
For colored fabrics, use a powdered oxygen-type bleach. Then wash the garment.
To remove chewing gum, use ice on the stain to make the chewing gum hard. Thenscrape most of it off the fabric. Next, use a nonflammable dry-cleaning solvent with
a sponge to remove the excess chewing gum. Wash the garment.
To remove coffee or chocolate stains, soak the garment in warm or cold water. Next,make a paste of detergent mixed with hot water, and brush it on the stain. Wash the
garment.
To remove a milk product stain, use a nonflammable dry-cleaning solvent with asponge. Wash the garment.

To remove antiperspirant and deodorant stains, wash the garment with laundrydetergent in the hottest water that is safe for the fabric. If the stain remains on the
fabric, place the stain face down on a white towel, and treat the stain with a paste of
ammonia and a powdered oxygen-type bleach. Let the paste stay on the stain for
30 minutes, and then wash the garment in the hottest water that is safe for the fabric.
To remove fruit stains, soak the stain in cool water. Do not use soapit will set thestain. Wash the garment. If the stain remains, cover the stain with a paste made of a
powdered oxygen-type bleach, a few drops of hot water, and a few drops of ammonia.
Let the paste stay on the stain for about 15 to 30 minutes. Then wash the garment.
To remove iron or rust stains, apply some lemon juice mixed with salt. Then placethe garment in the sun. Alternatively, a commercial rust-removing solution can be
used. Wash the garment.
Yellowing in Fabric
Some causes of yellowing in fabrics are:
Poor body soil removal
Clothes washed in water treated with a water softener
Hard water or minerals in the water, such as iron
Body oils released into the garment
The water supply might pick up the color of decaying vegetationTo remove body oils, the user will have to increase the amount of detergent and use
150-degree Fahrenheit wash water. The user must also increase the frequency of using
bleach in the wash.
To remove the yellowing from garments that are washed in water treated with a water
softener, the user will have to decrease the amount of detergent used, approximately to the
point that the decreased amount will not affect the soil removal process. The user must also
increase the frequency of using bleach in the wash.
Hard water and minerals in the water can be treated with a water-conditioning
apparatus. The user might have to drain the water heater and flush the tank. Never use
chlorine bleach to remove hard water stains or iron stains.
To remove body oils from the garment, use a paste made of detergent and water. Let it
stay on the fabric for 15 to 30 minutes. Then wash the garment.
To remove the yellowing caused by decaying vegetation, increase the amount of
detergent, and bleach more often. White fabrics typically respond quite well to bleaching.
Fabric Softener Stains
Fabric softener stains are becoming more prevalent because it is now being recommended
that some fabric softeners be used in the wash cycle, instead of the rinse cycle. These types
of stains show up on synthetics as well as cotton fabrics. They can be removed from the
fabric by pretreating the stain with liquid detergent and following the washing procedures
listed in the use and care manual.
PART VI
C h a p t e r 1 8 : To p L o a d A u t o m a t i c W a s h e r s
517Lint
Lint is cotton fiber that has broken away from the cotton garment. Lint likes to attach itself to
synthetic fabrics. When this happens, the user often thinks that the washer is not performing
properly. Therefore, to solve the problem of lint on synthetic fabrics, the user must sort the
items before washing the clothes. For example:
The user must separate cottons from permanent press and knits.
The user must separate light colors from dark colors.Another cause of lint on clothes is overwashing. This causes the clothes to wear out
faster. To correct the overwashing problem, use only one minute of wash time per pound of
dry laundry with normal soil. Any more time than this is a waste, and it usually does not
get the laundry cleaner.
If the drain cycle is excessive, this, too, will cause lint to remain on the garments.
Check for improper drain hose connections. For example:
Drain hose is too long (over 10 feet)
Drain hose is too high (over 5 feet)
Drain hose is kinkedIf excessive drain times still exist, check the following:
Check the filter, located under the wash basket on most newer models.
Check to be sure that the pump is operating properly.
Check for any obstructions in the drain system.
Check for any obstructions within the water circulatory system of the washer.Automatic Washer Maintenance
The interior is normally self-cleaning. However, there are times when you might have to
remove objects from the inner basket. Clean the control panel and outer cabinet with a soft
damp cloth. Do not use any abrasive powders or cleaning pads. Clean and inspect the
interior underneath the washer. Read the use and care manuals for the proper maintenance
of the brands of washers you service.
Cleaning the Interior of the Top Load Automatic Washer
Every one to two months the interior of the washer will need to be cleaned. This periodic
cleaning will remove any dirt, soil, mold, mildew, or bacteria residue that may remain in the
washer as a result of washing the clothes. To clean and freshen the washer interior:
1. Add a cup of chlorine bleach in the bleach dispenser. On some models, pour the
bleach in the wash water as the tub is filling with water.
2. Add Ό cup of detergent to the tub or detergent dispenser.
3. Run the washer without clothes through a complete cycle using only hot water.
4. Repeat the process if necessary.

Each repair procedure is a complete inspection and repair process for a single washer
component, containing the information you need to test a component that might be faulty
and to replace it, if necessary.
Any person who cannot use basic tools should
not attempt to install, maintain, or repairany top load washer. Any improper installation, preventative maintenance, or repairs will
create a risk of personal injury, as well as property damage. Call the service manager if
installation, preventative maintenance, or the repair procedure is not fully understood.
Washer Timer
The washer timer is an electromechanical component controlled by a synchronous motor in
incremental advances. It controls and sequences the numerous steps and functions involved
in each cycle.
The typical complaints associated with washing machine timer failure are:
The cycle will not advance.
The washer wont run at all.
The washer will not fill.
The washer will not pump the water out.
The washer will not shut off.To handle these problems, perform the following steps:
1.
Verify the complaint. Verify the complaint by operating the washer through itscycles. Before you change the timer, check the other components controlled by the
timer. If the washer will not power up, locate the technical data sheet behind the
control panel for diagnostics information. On some models you will need the actual
service manual for the model you are working on to properly diagnose the washer.
2.
Check for external factors. You must check for external factors not associated withthe appliance. Is the appliance installed properly? Does the appliance have the
correct voltage? The voltage at the receptacle is between 108 volts and 132 volts
during a load on the circuit. Do you have the correct polarity? (See Chapter 6.)
3.
Disconnect the electricity. Before working on the washer, disconnect the electricity.This can be done by pulling the plug out from the electrical outlet. Be sure that you
only remove the washer plug. Or disconnect the electricity at the fuse panel or the
circuit breaker panel. Turn off the electricity.
W
ARNING Some diagnostic tests will require you to test the components with the power turned on.When you disassemble the control panel, you can position it in such a way that the wiring will
not make contact with metal. This act will allow you to test the components without electrical
mishaps.

541The typical complaints associated with capacitor failure are:
Fuse is blown or the circuit breaker trips.
Washer motor will not run.
Motor has a burning smell.
Motor will try to start and then shuts off.To handle these problems, perform the following steps:
1.
Verify the complaint. Verify the complaint by operating the washer. Listencarefully, and you will hear if there are any unusual noises or if the circuit breaker
trips. If you smell something burning, immediately turn off the washer and pull the
plug. On electronic models, if a fault code appears, look up the code. If the washer
will not power up, locate the technical data sheet behind the control panel for
diagnostics information. On some models you will need the actual service manual
for the model you are working on to properly diagnose the washer. The service
manual will assist you in properly placing the washer in the service test mode for
testing the washer functions.
2.
Check for external factors. You must check for external factors not associated withthe appliance. Is the appliance installed properly? Does the appliance have the
correct voltage? The voltage at the receptacle is between 108 volts and 132 volts
during a load on the circuit. Do you have the correct polarity? (See Chapter 6.)
3.
Disconnect the electricity. Before working on the washer, disconnect the electricity.This can be done by pulling the plug from the electrical outlet. Be sure that you only
remove the washer plug. Or disconnect the electricity at the fuse panel or at the
circuit breaker panel. Turn off the electricity.
W
ARNING Some diagnostic tests will require you to test the components with the power turned on.When you disassemble the control panel, you can position it in such a way that the wiring will
not make contact with metal. This act will allow you to test the components without electrical
mishaps.
4.
Gain access to the capacitor. Some models have the capacitor mounted on themotor, and some are mounted to the cabinet interior in the rear of the machine.
Access might be achieved through the front or rear panel, depending on which
model you are working on. Do not touch the capacitor until its discharged.
W
ARNING A capacitor will hold a charge indefinitely, even when it is not currently in use. Acharged capacitor is extremely dangerous. Discharge all capacitors immediately any time that
work is being conducted in their vicinity. Redischarge after repowering the equipment if further
work must be done.
542
P a r t V I : A p p l i a n c e S e r v i c e , I n s t a l l a t i o n , a n d P r e v e n t i v e M a i n t e n a n c e P r o c e d u r e s5.
Test capacitors. Before testing the capacitor, it must be discharged. Use a screwdriverwith an insulated handle to discharge the capacitor by shorting it across both terminals.
Remove the wire leads, one at a time, with needle-nose pliers. Set the ohmmeter on the
highest scale and then place one probe on one terminal and the other probe on the other
terminal (Figure 18-30). Observe the meter action. While the capacitor is charging, the
ohmmeter will read nearly zero ohms for a short period of time. Then the ohmmeter
reading will slowly begin to return toward infinity. If the ohmmeter reading deflects to
zero and does not return to infinity, the capacitor is shorted and should be replaced.
If the ohmmeter reading remains at infinity and does not dip toward zero, the
capacitor is open and should be replaced.
Another way to test a capacitor is to attach a capacitor tester to it and test the
microfarad reading. It should be within +/ 10 percent of the capacitor rating that
is stamped on the side of the capacitor. By using a capacitor tester, you will be able
to test for a weak capacitor even if it tests out okay with an ohmmeter.
6.
Remove the capacitor. Remove the capacitor from its mounting bracket.7.
Install a new capacitor. To install the new capacitor, just reverse the disassemblyprocedure, and reassemble.
Note: A capacitor is rated by its working voltage (WV orWVac) and by its storage capacity in microfarads (
μF). Always replace a capacitorwith one that has the same voltage rating and the same (or up to 10 percent greater)
microfarad rating.
Drive Belt
The typical complaints associated with belt failure are:
Washer will not agitate.
Washer will not spin.
Washer motor spins freely.

543To handle these problems, perform the following steps:
1.
Verify the complaint. Verify the complaint by operating the washer in the spincycle. Listen carefully, and you will hear and see if the inner basket is turning or if
the circuit breaker trips. On electronic models, if a fault code appears, look up the
code. If the washer will not power up, locate the technical data sheet behind the
control panel for diagnostics information. On some models you will need the actual
service manual for the model you are working on to properly diagnose the washer.
The service manual will assist you in properly placing the washer in the service test
mode for testing the washer functions.

during a load on the circuit. Do you have the correct polarity? (See Chapter 6.)
3.
Disconnect the electricity. Before working on the washer, disconnect the electricity.This can be done by pulling the plug out from the electrical outlet. Be sure that you
only remove the washer plug. Or disconnect the electricity at the fuse panel or at
the circuit breaker panel. Turn off the electricity.
W
ARNING Some diagnostic tests will require you to test the components with the power turned on.When you disassemble the control panel, you can position it in such a way that the wiring will
not make contact with metal. This act will allow you to test the components without electrical
mishaps.
4.
Gain access to the belt. You must gain access to the beltwhether by removing theback or the front panel, tilting the washer, or laying it onto its backdepending on
which model washer you are working on. The back panel (or the front panel) is
usually held on with two screws. Remove the screws, and remove the panel.
5.
Adjust the belt. Before adjusting the belt, use your finger and press on the belt; itshould only deflect about 1/4 inch. To adjust the belt (see Figure 18-16), loosen the
motor bracket nut just enough to move the bracket. Take hold of the motor bracket,
and pull against the belt just enough to take up the slack in it and to properly retension
it. If you are unable to adjust the tension, or if the belt is worn, replace the
belt. Some models have more than one belt: one is for the drive system that is
attached to the motor and the transmission pulleys; the other belt is for the water
pump. This belt is attached to the motor pulley and to the water pump pulley
(Figure 18-31). To adjust the water pump belt in this type of washer, just loosen the
pump mounting screws and adjust to obtain the correct tension, about 1/4-inch
deflection. There are even some models that use a direct-drive system (which has
no belts) to drive the motor, transmission, and pump (Figure 18-32). This type of
washer has the motor and the water pump attached to the transmission with
retaining clips.

545Between the motor shaft and the transmission, there is a coupling. To replace this
coupling, remove the retaining clips that secure the water pump and the motor.
Install the new coupling, and reattach the motor and the water pump.
6.
Replace the drive belt. To replace the drive belt on this type of washer, you mustremove the flexible pump coupling (Figure 18-33). Next, loosen the motor bracket
nuts, and slide the motor forward to take the tension off the belt. Then remove the
belt from the motor pulley and the transmission pulley (Figure 18-34). Install the
new belt on the transmission pulley and the clutch pulley. Be sure that the belt is in
the pulley grooves. Next, adjust the belt tension, and tighten the motor bracket nuts.
Reinstall the flexible pump coupling and clamps, making sure that the coupling is
not twisted and that it is seated on the pump and clutch pulleys. The drive belt
tension on this type of washer should be approximately 1/2 inch when deflected.
7.
Test the washer. You are now ready to test the washer. Begin the wash cycle with afull load of laundry in the basket. Check the agitate and the spin cycles. If these check
out okay, reinstall the outer panels. If not, readjust the belt tension.
Water Level Control
The water level control starts in the empty position. As the washer fills with water and the
water level rises in the tub, it causes the air pressure in the tube and in the air dome to
increase (Figure 18-35). The air pressure is transferred from the air hose to the water level
control and against the diaphragm, which actuates the water level switch to the full position
and agitation begins.

the way.
3.
Disconnect the electricity. Before working on the washer, disconnect the electricity.This can be done by pulling the plug from the electrical outlet. Be sure that you only
remove the washer plug. Or disconnect the electricity at the fuse panel or at the

4.
Remove the console panel to gain access. Begin by removing the console panel togain access to the water level control (see Figure 18-2).
5.
Test the water level control. To test the water level control switch, remove and labelall of the wires from the switch (Figure 18-36). Remember, you will have to identify the
wires according to the wiring diagram in order to reinstall them on the water level
control switch properly. With the washer empty, use your ohmmeter (set on R
Χ 1),and test it for continuity on the switch contacts numbered 1 and 2 (Figure 18-37). If
you have continuity, this means that the water valve will be energized, allowing
the water to enter the tub. Now test for continuity between contacts 1 and 3; the
ohmmeter should read no continuity. Reconnect the wires to the water level switch.
Plug in the washer, and start the wash cycle. Let the console rest on top of the
washing machine for this test. Be careful not to touch any live wires or to short them
to the washer chassis while the test is being performed. As the water level rises in the
tub, it forces air through the air dome and up the plastic tube to the water level
control. The pressure that is exerted on the water level controls diaphragm will trip
the water level switch from empty to full, which will start the agitation cycle. When
the agitation cycle begins, turn off the washer. Pull the power plug from the wall
socket to ensure that power has been removed.

ohmmeter should read no continuity. Next, test for continuity between contacts
numbered 1 and 3. The ohmmeter will read continuity. If the water level switch
checks out, then check the plastic hose that goes from the air dome to the water
level control. Ensure that there are no holes or cracks in the line. If the switch does
not check out okay, replace it. Remember: Never blow into the water level control
switch to activate it. Why? You might activate the switch, but it will not prove that
the switch will activate (at lesser pressures) at the proper water level setting
selected.

Lid Switch
On some models, the lid switch will pause the spin operation; on other models, it will pause
the wash operations, except water fill. Once the washer cycle is started, the washer lid
should remain closed until the end of the wash cycle. The lid switch is a safety device added
to protect consumers from getting entangled within the washer. Never bypass this switch.
The typical complaints associated with the lid switch are:
Washer will not spin.
Washer will not agitate.To handle these problems, perform the following steps:
1.

ARNING Some diagnostic tests will require you to test the components with the power turned on.When you disassemble the control panel, you can position it in such a way that the wiring will
not make contact with metal. This act will allow you to test the components without electrical
mishaps.
4.
Remove the defective hose. To remove the defective hose, the tub must be emptyof water. Loosen the clamps that hold the hose in place. On some models, the
manufacturer uses a snap ring clamp. To remove this type of clamp, just squeeze
the ends together (Figure 18-55).

561Clutch
Clutches are used for braking (slowing and stopping the inner basket) and/or allowing the
turning of the inner basket to get up to speed.
The typical complaints associated with the clutch are:
Washer will not agitate.
Washer will not spin.To handle these problems, perform the following steps:
1.
Verify the complaint. Verify the complaint by operating the washer. On electronicmodels, if a fault code appears, look up the code. If the washer will not power up,
locate the technical data sheet behind the control panel for diagnostics information.
On some models you will need the actual service manual for the model you are
working on to properly diagnose the washer. The service manual will assist you in
properly placing the washer in the service test mode for testing the washer
functions.
