This washer has a heating element that automatically heats the water to the best temperature on select cycles. This enables stepped cleaning, a process in which warm water is brought in and mixed with detergent first, then the water is heated.
PRODUCT OPERATION THEORY OF OPERATION INTRODUCTION The flowmeter is also used to introduce additional water into the tub for higher water levels, based on cycle requirements. The Maytag Epic Front-Loading Automatic Washer presents a number of new features and operating characteristics quite different from previous models. The washer contains a number of unique operating features designed to increase clothes cleaning ability while offering very high water and energy conservation.
The dispenser drawer has four separate compartments for adding laundry products to the wash load. These compartments are: 1. Prewash Detergent Compartment 2. Main Wash Detergent Compartment 3. Bleach Compartment 4. Fabric Softener Compartment The water enters the wash tub through the main inlet tube. Main Inlet Tube 1 2 3 AIR VENT SYSTEM 4 As a safety feature, the washer is designed to allow fresh air to circulate through the tub. An inlet vent at the rear of the washer brings air into the tub.
PRESSURE SWITCH The pressure switch also senses the suds level in the wash tub. If excessive sudsing occurs, the washer starts an automatic suds routine. The display will show the word “Sud.” The automatic suds routine adds additional rinse and drain operations until the suds level is reduced. If an overfill condition is detected by the pressure switch, the CCU will turn on the drain pump and attempt to stop filling. The pressure switch is located in the top right rear corner of the washer.
TOUCHPAD/LED ASSEMBLY MOTOR CONTROL UNIT (MCU) The Touchpad/LED Assembly is removed as a single assembly and is connected to the Central Control Unit by a ribbon cable. This assembly contains all of the buttons, LEDs and ribbon cable and printed circuit boards for the user to operate the washer. This interfaces the consumer inputs to the Central Control Unit. The Motor Control Unit is located inside a plastic control box located in the lower front corner of the washer cabinet.
PUMP MOTOR SUSPENSION SYSTEM A separate pump/pump motor is used to drain the wash tub. The wash tub is held in position with four shock absorbers attached to the bottom four corners of the tub assembly. In addition, the wash tub is suspended from the top frame of the washer with two springs attached to the sides of the unit. Stability for this suspension system is provided by three concrete counterweights. Two are located at the front of the wash tub. One is positioned at the back of the tub.
HEATING ELEMENT & TEMPERATURE SENSOR The assembly contains a solenoid operated latching mechanism that will electrically lock the door during a wash cycle. A heating element is used to increase the water temperature during certain wash cycles. The temperature sensor is used with the heater to monitor water temperature in the tub.

12234563789 8 This washer allows an 8-minute period in which forgotten garments may be added to the load. You can add items to the washer if the ADD A GARMENT status light is glowing. Cycles can be selected by turning the Cycle control knob to the desired cycle. Each cycle is designed for different types of fabric and soil levels. 12345536789 Select PAUSE/OFF once. The washer door unlocks, and items can be added.
12345672 2 27 5 532 2774 Use this cycle to wash no-iron fabrics and garments labeled “ Permanent Press” or “Wrinkle Free” or that indicate using a “ Gentle” cycle on the care label. This cycle combines low-speed tumbling and low-speed spin to reduce wrinkling. Each cycle has a preset Soil Level (cycle time), Water Temperature, and Spin Speed. The preset settings provide the recommended fabric care for the selected cycle. See chart. 8439 Use this cycle to clean washable silk garments.
1234567 95 4 4 7 You can customize your wash by adding options to your cycle selections. You can add or change an option after starting a cycle anytime before the selected option begins. Not all options are available with all cycles. Preset cycle settings of Soil Level (cycle time), Water Temperature, and Spin Speed can be changed. You can change a modifier after starting a cycle anytime before the selected modifier begins. Not all modifiers are available with all cycles and options.

123456789 8 8 8 Follow these recommendations to help you prolong the life of your garments. Use only High Efficiency detergents. The package for this type of detergent will be marked HE or High Efficiency. This wash system, along with less water, will create too much sudsing with a regular non-HE detergent. Using regular detergent will likely result in washer errors, longer cycle times and reduced rinsing performance.

COMPONENT TESTING Before testing any of the components, perform the following checks: • Control failure can be the result of corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures. • All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohmsper-volt DC, or greater. • Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.
