Important Safety Information
Electrical Equipment & Testing
Electrical Test Equipment
The equipment required to service these models depends
largely upon the condition encountered. Locating a
malfunction will often require the use of electrical testing
equipment such as:
Appliance Test Meter
Clamp-On Ammeter
Motor Test Cord
Digital Test Meter
can be used to check for open
or closed circuits, measure
resistance, AC and DC volts,
and temperature.
Appliance Test Meter
An Appliance Test Meter is a multi-purpose tester
combining an AC/DC voltage tester with a multi-range
ohmmeter.
The easiest means of testing electrical components is
"Continuity Testing" with an appliance meter. Continuity
is a complete or continuous path from one point in an
electrical circuit to another.
Analog Test Meter
can be used to check for
open or closed circuits,
measure resistance, AC and
DC volts, and temperature.
The obvious advantages of being able to check electrical
components and circuits without power applied is one of
the features of the Ohmmeter. Multiple ranges allow
accurate determination of resistances of both single
components and entire circuit paths. Resistance is
measured in "Ohms."
! WARNING
To avoid risk of personal injury or death due to
electrical shock:
Always be sure the power has been disconnected
before making resistance measurements. Failure to
do so will also result in damage to your meter!
Internal batteries provide all the power needed to
make resistance checks. They should be checked
at least once a year and replaced as needed.
Continuity Testing: is a process of eliminating electrical
components involved in a given function of the appliance,
until the inoperative part is found. By reviewing the list of
possible electrical problems under a given condition, and
then performing appropriate continuity checks of the parts
involved, you should be able to locate the electrical
component which is inoperative.
NOTE: When checking components or circuit paths for
continuity, external wiring should be disconnected to
eliminate false readings through external paths. Isolate
what you want to test.

ELECTRICAL EQUIPMENT & TESTING
VOLTAGE CHECKS
Use of Ammeter on dishwasher:
Generally, these checks will consist of taking readings
at the wall receptacle in order to determine the
availability of voltage to the product. Voltage checks on
individual components of a product are not
recommended due to the possibility of electrical shock.
Component part testing is best accomplished through
continuity checks with an Appliance Test Meter.
1. Motor Current - the reading can be taken at the
leads on the motor start relay or at the male connector.
NOTE: Use of the meter on voltage higher than the
indicated range may cause permanent damage to the
meter. To prevent damage, first select highest range and
then lower the range for readings which fall within the
lower scale.
Motor Test Cord
Clamp-On Ammeter
can be used to detect shorts.
Overloads on the circuit breaker
or fuse can be traced
to either the appliance
or circuit breaker by
checking the current
draw.
2. Heating Element Current - The reading can be
taken using either lead to the element.
! DANGER
To avoid risk of personal injury or death due to
electrical shock:
• Disconnect electrical power to dishwasher before
servicing.
• Always plug test cord into a properly grounded
receptacle.
• Always make connection to components before
plugging test cord into receptacle.
Each circuit in an appliance has a "Normal" current
draw, which is an indication of the performance of that
circuit. Current draw levels of less than or more than
normal give clues to possible malfunctions. The clampon ammeter measures these circuits without breaking
the circuit by measuring the strength of the magnetic
field developed around each conductor. Current is read
by separating the conductors and clamping the jaws of
the ammeter around each conductor on which current is
read. Low amperage readings indicate problems, such
as damaged heating elements, etc. High amperage
readings indicate the unit being tested is operating under
an increased mechanical or electrical load.
NOTE: Overloads on a circuit breaker or fuse can be
traced to the product being tested or the circuit breaker
(or fuse) by checking the products current draw. If the
amperage reading is less than the breaker reading, the
breaker or fuse box is at fault.
A motor test cord may be used to electrically check
operation of the various electrical components without
removing them from the unit. Testing in this manner
merely determines whether or not the part will function
independently of other electrical components. In order to
make accurate tests, proper connection of the motor test
cord is important. With the aid of the drawings under
Drive Motor Test, installation of the motor test cord may
be done quickly and accurately.
Grounding and Polarity
! DANGER
To avoid risk of personal injury or death due to
electrical shock:
• Do not cut or remove the grounding prong from any
plug.
The receptacle used for all Maytag products operating on
120 VAC must be properly grounded and polarized.
The power cord used on the appliances should be
equipped with a three (3) prong polarized grounding plug
8
16022783 Rev. 0
©2004 Maytag Appliances Company
Electrical Equipment & Testing
for protection against shock hazard and should be
plugged directly into a properly grounded and polarized
receptacle.
It is the responsibility of the person installing the
appliance to assure it is adequately grounded and
polarized at the point of installation, taking into
consideration local conditions and requirements. In
cases where only a two (2) prong receptacle is available,
it is the personal responsibility of the consumer to have it
replaced with a properly grounded three (3) prong
receptacle. All grounding and wiring should be done in
accordance with National, State, and Local codes. DO
NOT USE AN ADAPTER PLUG WITH THIS
APPLIANCE.
ELECTRICAL TESTS
Wax Motor Check
Detergent / Rinse Aid Dispenser
A single Wax Motor is used to activate both the release of
the Detergent Cup Cover and the rinse aid from the
reservoir.
To check the operation of the Wax Motor, removal from
the Dispenser Retainer or Inner Door is not necessary.
First, snap the Detergent Cup Door shut. Then, connect
a Power Test Cord across the two terminals of the Wax
Motor. Plug the Power Test Cord into a 120 VAC
receptacle. The plunger in the center of the Wax Motor
should "push out" and actuate the Dispenser in
approximately 45-60 seconds. Remove voltage to the
Wax Motor and allow the plunger to retract into the Wax
Motor. Apply voltage to the Wax Motor again and observe
for proper lifting of the rinse aid plunger.
! WARNING
To avoid risk of personal injury or death due to
electrical shock:
• Disconnect electrical power to dishwasher before
servicing.
• Always plug test cord into a properly grounded
receptacle.
• Always make connection to components before
plugging test cord into receptacle.
WATER VALVE TEST
The Water Valve may be checked without removing it from
the Dishwasher.
To check the Water Valve for operation, hook up the test
cord as follows:

WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and discharge
capacitor through a 10,000 ohm resistor before attempting to service, unless test procedures require power to be
connected. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
The following paragraphs describe how to disassemble
unit under test. Disassembly to some extent is required
to install unit, to perform troubleshooting procedures, and
to remove and replace failed components.
Component names used throughout disassembly
procedures are the same as those used in Parts
Manuals.
For quicker reassembly, disassemble unit under test only
to extent necessary to troubleshoot and repair. Unless
noted, reassembly is opposite of disassembly.
! WARNING
To avoid risk of personal injury or death due to
electrical shock, ground wires and wires colored like
ground wires are NOT to be used as current carrying
conductors. The standard accepted color coding for
ground wires is green or green with a yellow
stripe. Electrical components such as the water valve
and motor are grounded through an individual wire
attached to the electrical component. Ground wires
should not be removed from individual components
while servicing, unless the component is to be
removed and replaced. It is extremely important to
replace all removed ground wires before completing
service.

capacitor through a 10,000 ohm resistor before attempting to service, unless test procedures require power to be
connected. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
Heating Element
The purpose of the Heating Element is to provide heat
during the dry cycle and increase water temperature
during portions of the wash cycle when certain options are
selected.
The element is dual wattage. During wash cycles, it is
rated at 830 watts. During the dry portion of the cycle, it
is rated at 650 watts. Increased wattage is possible
because of water flowing across the element sheath.
To Check Heating Element
1.
Disconnect power to the machine.
2.
Remove Front Support and Toe Panel. (See paragraph
Front Support and Toe Panel removal).
3.
Locate element terminals, remove wires, perform
continuity check across terminals.
4.
The resistance of the element should be
approximately 22 ohms. If OPEN, replace element.
5.
Perform continuity check from each terminal to the
element sheath. NO continuity should be present. If
continuity is present, replace the element.
Wattage Checks
Removal
1.
Disconnect power to the machine.
2.
Remove Front Support and Toe Panel. (See paragraph
Front Support and Toe Panel removal).
3.

39
NOTE: Before reinstalling Heating Element, examine
condition of O-ring seals that are located between
element leads and tub basin. Replace if needed.
Failure of seal will result in a water leak and
possible floor damage.
To verify wattage of the element, take an amperage
reading at the blue wire of the Heating Element. Multiply
the amperage reading by voltage at the Dishwasher
(Amps x Volts = Watts).
Normal element amperage during the dry portion of the
cycle is 5.0 to 5.5 amps. When used during a wash
cycle, normal amperage is 7.0 to 7.5 amps.

Thermostats
Water Valve
Two types of thermostats are used in the Dishwasher. A
Thermistor and a Limit Thermostat.
The valve is located behind the Support and Toe Panel,
mounted to the left side of the Tub Support. Inlet water
supply to the valve is directly below the valve.
The Thermistor is used to sense water temperature when
certain cycles or options are selected (Refer to Cycles &
Options section). The Thermistor is part of the sensor
mounted in the Tub.
The other thermostat is a Limit Thermostat and is used as
a protective device to sense overheating of the Heating
Element. It is located behind the Front Support and Toe
Panel. The limit is mounted to the tub bottom. This
thermostat has ¼" terminals and has a normally CLOSED
position.
