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.

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.

16022783 Rev. 0

Analog Test Meter

can be used to check for open or closed circuits, measure resistance, AC and

DC volts, and temperature.

ELECTRICAL EQUIPMENT & TESTING

Use of Ammeter on dishwasher:

VOLTAGE CHECKS

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.

2.

Heating Element Current

- The reading can be taken using either lead to the element.

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.

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.

Motor Test Cord

!

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.

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.

8

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.

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

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:
