Important Safety Information
when required. Do not do it yourself unless you know how!
To reduce the risk of fire, electric shock, serious injury or death to persons when using your washer, follow these basic precautions:
• Read all instructions before using the washer.
• Refer to the Grounding Instructions in the Installation Manual for the proper grounding of the washer.
• Do not wash articles that have been previously cleaned in, washed in, soaked in, or spotted with gasoline, dry-cleaning solvents, or other flammable or explosive substances as they give off vapors that could ignite or explode.
• Do not add gasoline, dry-cleaning solvents, or other flammable or explosive substances to the wash water. These substances give off vapors that could ignite or explode.
• Under certain conditions, hydrogen gas may be produced in a hot water system that has not been used for two weeks or more. Hydrogen gas is explosive. If the hot water system has not been used for such a period, before using a washing machine or combination washer-dryer, turn on all hot water faucets and let the water flow from each for several minutes. This will release any accumulated hydrogen gas. The gas is flammable, do not smoke or use an open flame during this time.
• Do not allow children to play on or in the washer. Close supervision of children is necessary when the washer is used near children. This is a safety rule for all appliances.
• Before the washer is removed from service or discarded, remove the lid to the washing compartment.
• Do not reach into the washer if the wash tub is moving.
• Do not install or store the washer where it will be exposed to water and/or weather.
• Do not tamper with the controls.
• Do not repair or replace any part of the washer, or attempt any servicing unless specifically recommended in the User-Maintenance instructions or in published user-repair instructions that you understand and have the skills to carry out.
• To reduce the risk of an electric shock or fire, do not use an extension cord or an adapter to connect the washer to the electrical power source.
• Use your washer only for its intended purpose, washing clothes.
• Always disconnect the washer from electrical supply before attempting any service. Disconnect the power cord by grasping the plug, not the cord.
• Install the washer according to the Installation Instructions. All connections for water, drain, electrical power and grounding must comply with local codes and be made by licensed personnel
4 16026126 Rev. 0 ©2005Maytag Services
• To reduce the risk of fire, clothes which have traces of any flammable substances such as vegetable oil, cooking oil, machine oil, flammable chemicals, thinner, etc. or anything containing wax or chemicals such as in mops and cleaning cloths, must not be put into the washer. These flammable substances may cause the fabric to catch on fire by itself.
• Do not use fabric softeners or products to eliminate static unless recommended by the manufacturer of the fabric softener or product.
• Keep your washer in good condition. Bumping or dropping the washer can damage safety features. If this occurs, have your washer checked by a qualified service person.
• Replace worn power cords and/or loose plugs.
• Be sure water connections have a shut-off valve and that fill hose connections are tight. Close the shut-off valves at the end of each wash day.
• Loading lid must be closed any time the washer is in operational fill, tumble, or spin. Do not attempt to bypass the loading lid switch by permitting the washer to operate with the loading lid open.
• Always read and follow manufacturer’s instructions on packages of laundry and cleaning aids. Heed all warnings or precautions. To reduce the risk of poisoning or chemical burns, keep them out of the reach of children at all times (preferably in a locked cabinet).
• Always follow the fabric care instructions supplied by the garment manufacturer.
• Never operate the washer with any guards and/or panels removed.
• Do not operate the washer with missing or broken parts.
• Do not bypass any safety devices.
• Failure to install, maintain, and/or operate this washer according to the manufacturer’s instructions may result in conditions which can produce bodily injury and/or property damage.
NOTE: The Warnings and Important Safety Instructions
appearing in this manual are not meant to cover all possible conditions and situations that may occur. Common sense, caution and care must be exercised when installing, maintaining, or operating the washer.
Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do not understand.
Important Safety Information
To avoid personal injury or death from improper servicing, make sure you read and understand the descriptions and meaning of various safety symbols, words and labels used in this manual, before attempting any procedures described in the manual. Failure to understand and comply with safety information may result in severe personal injury or death.
General Information
This Service Manual describes the operation, disassembly, troubleshooting, and repair of the Compact washer. It is intended for use by authorized technicians who troubleshoot and repair these units.
NOTE: It is assumed that users of this manual are
familiar with the use of tools and equipment used to troubleshoot and repair electrical, and mechanical systems; and understand the terminology used to describe and discuss them.
About Ground Wires
In the event of an electrical short circuit, a ground wire reduces the risk of electric shock by providing an escape wire for the electric current. Standard accepted color coding for ground wires is green or green with a yellow stripe. Grounding wires and wires colored like grounding wires are NOT to be used as current carrying conductors.
To reduce the risk of fire, electric shock, serious injury or death, all wiring and grounding must conform with the latest edition of the National Electric Code, ANSI/ NFPA 70, or the Canadian Electrical Code, CSA C22.1, and such local regulations as might apply. It is the customer’s responsibility to have the wiring and fuses checked by a qualified electrician to make sure your home has adequate electrical power to operate the washer.

Important Safety Information
Explanation Polarization–This means that the larger slot must be
neutral and the small slot must be at line voltage. Mispolarized–The outlet is incorrectly wired so that the larger slot is at line voltage and the smaller slot is neutral. Grounded–This means the round hole connection is con­nected to earth ground through a connection to the main power panel. Ungrounded–The round hole connection is not complete to earth ground and/or the main power panel.
Grounding Instructions
• To avoid the risk of electrical shock or death, do not alter the plug.
• Do not remove grounding prong when installing grounded appliance in a home that does not have three wire grounding receptacle. Under no condition is grounding prong to be cut off or removed. It is the personal responsibility of the consumer to contact a qualified electrician and have properly grounded three prong wall receptacle installed in accordance with appropriate electrical codes.
• To avoid the risk of electrical shock or death, this equipment must be grounded.
This equipment MUST be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This unit is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded. Consult a qualified electrician or technician if grounding instructions are not completely understood, or if doubt exists as to whether the equipment is properly grounded. Do not use an extension cord. If the product power cord is too short, have a qualified electrician install a three-slot receptacle. This unit should be plugged into a separate 60 hertz circuit with the electrical rating as shown in the appropriate drawing. Models operate with a supply voltage of 120 Volts.
