Page 13: Level The Washer
Level the Washer Properly leveling your washer prevents excessive noise and vibration. 1. Check the levelness of the washer by placing a level on the top edge of the washer, first side-to- side, then front-to-back. If the washer is against a wall, move the washer out slightly before tipping back. - Page 14 WARNING EXCESSIVE WEIGHT HAZARD Use two or more people to move washer and dryer. Failure to do so can result in back or other injury. Important: If the washer is already installed, it must be uninstalled. See installation instructions that came with the washer for tools required.

Page 17: Theory Of Operation
THEORY OF OPERATION Front-Loading Automatic Washers present a number of new features and operating characteristics quite different from previous models. In addition to the introduction of front-loading operation, The washers contain a number of unique operating features designed to increase clothes cleaning ability while offering very high water and energy conservation. Water System The water system consists of the hot and cold water inlet valves, a water temperature sensor, a water flowmeter and control and the dispenser distribution system along with a traditional pressure switch. - Page 18 The dispenser drawer has four separate compartments for adding laundry products to the wash load. These compart- ments are: 1. Prewash Detergent Compartment 2. Main Wash Detergent Compartment 3. Bleach Compartment 4. Fabric Softener Compartment Laundry products are diluted and dispensed automatically at the proper time during the wash cycle.
- Page 19 Pressure Switch The pressure switch is located in the top right rear corner of the washer. (Fig. 3-7) This switch senses water level in the wash tub. The control signal from the pressure switch is sent to the Central Control Unit and is used to determine the amount of water introduced into the wash tub during the wash cycle.
- Page 20 CYCLE DESCRIPTION Sanitary Use this cycle to clean heavily soiled colorfast fabrics. This cycle combines a very hot water tempera- ture and fast speed tumbling to help ensure the removal of heavy soils and stains. It is recommended that you set your hot water heater to 120º F (49º C) to ensure proper performance during this cycle. The Sanitary cycle also helps kill bacteria, even when no bleach is used.
- Page 21 Cycle Sanitary Whitest Whites Heavy Duty Normal/ Casual Quick Wash Delicate Silk Wool Hand Washables Soak Use the Soak cycle to remove small spots of set-in stains on fabrics. This cycle provides a soak time with warm or cold water followed by drain. Extra water, a short tumbling phase for equal distribution of the laundry, and a soaking time without basket movement improve the removal of set-in stains.

- Page 23 Options You can customize your wash by adding OP- TIONS to your cycle selections. You can add or change an option after starting a cycle anytime before the selected option begins. • See the “Laundry Guide” for an overview of possible options for each Wash Cycle selec- tion.
- Page 24 Without a Wash Cycle: Provides a soak time with warm or cold water followed by drain. 1. Add detergent only to the Prewash compart- ment of the Dispenser Drawer. 2. Select DRAIN/SPIN or RINSE/SPIN first, then AUTO SOAK. 3. Choose the desired soak temperature. 4.
- Page 25 Touch Pad/LED Assembly The Touch Pad/LED Assembly, (Fig. 3-10) , 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.

Page 26: Pump Motor
Pump Motor A separate pump/pump motor is used to drain the wash tub. (Fig. 3-14) The pump motor is 120 VAC and is attached directly to the pump. The pump has a cleanout filter located at the front that allows for the removal of large objects that may have passed from the basket. - Page 27 Heating Element and Temperature Sensor Model GHW9200L provides a heating element to increase the water temperature during certain wash cycles. The temperature sensor is used with the heater to monitor water tem- perature in the tub. (Fig. 3-18) Fig. 3-18 Door Lock/Switch Assembly The Door Lock/Switch Assembly is located on the right side of the door opening.

Required Tools The Front-Loading Automatic Washer requires the use of Metric Sockets of various sizes, Torx T-20 and T-25 Drivers, a Crescent Wrench, a flat bladed screwdriver and a hammer. ACCESSING COMPONENTS IN THE CONSOLE Components accessible in the Console include the Console Cover and the Touch Pad/LED As- sembly. - Page 31 Begin by removing the cycle selector knob. There are eight tabs securing the Touch Pad/LED As- sembly to the console. (Fig. 4-8) A flat bladed screwdriver will be helpful in releasing these tabs. Fig. 4-8 REMOVING THE WASHER DOOR AND DOOR SWITCH The washer door can be removed by removing the upper left shield cover and hinge cover.
- Page 32 REMOVING THE WASHER FRONT PANEL Removing the washer front panel will require that the door switch be removed and the boot be sepa- rated completely from the front panel opening. The console must also be removed. Next, remove the three screws securing the toe panel to the front of the washer (Fig.
- Page 33 REMOVING THE DETERGENT DISPENSER ASSEMBLY The Detergent Dispenser Assembly is located under the washer top. Begin by removing the washer top, console and front panel. Separate the water inlet and window washer tube from the boot. Pull the water inlet tube from the outlet connector of the detergent dispenser.
- Page 34 REMOVING THE CENTRAL CONTROL UNIT AND PRESSURE SWITCH The Central Control Unit is a single assembly and does not contain any serviceable parts. It can be removed by lifting the top plastic tabs securing it to the back cabinet frame and sliding it towards the front of the washer.
- Page 35 To clean out the large item filter, turn the large knob counterclockwise and pull it out. (Fig. 4-24) NOTE: It is recommended that a small pan be placed under the pump prior to removing the large item filter. There will be water in the pump hous- ing.

Page 45: Diagnosis And Troubleshooting
DIAGNOSIS & TROUBLESHOOTING During Drain Routine During the Drain Routine, the water level is checked continuously. Normal drain will occur until the pressure switch senses no water in the wash tub and there is no foam (suds). The drain pump will operate an additional 15 seconds after the pressure switch reports no water or foam. -
Page 46: Door Locking And Unlocking
DOOR LOCKING AND UNLOCKING Locking The Door Locking Routine will only start if the door is securely closed and the Door Switch Contact is CLOSED. 1. The Door Lock Relay is energized whenever a wash cycle is started. The relay is operated for 40 milliseconds. -
Page 47: Unbalance Detection Routine
Unbalance Detection Routine The unbalance detection routine occurs during the distribution ramp (while basket spin is accelerat- ing from 40 to 400 rpm). At 400 rpm the motor is decelerated and the rate of deceleration is moni- tored by the CCU. The motor is then ramped up to 400 rpm and shut off. The rate of deceleration is monitored again and compared to the first deceleration rate. -
Page 48: Error Codes
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE No water detected entering machine or Pressure switch trip not detected. If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed. If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash. - Page 49 DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE F/06 Drive Motor Tachometer Error The control is unable to properly detect motor speed and the machine will shut down.
