11 Theory of operation INTRODUCTION The Washer several familiar features signs integrat them into this new design. Drive system DRIVE SYSTEM Motor Bi-directional PSC (Permanent Split Capacitor) 120VAC. Agitation and variable spin speeds are accomplished by applying power in pulses. Transmission The transmission is a non-serviceable belt driven component. - Inner shaft top splines connect to the agitator. - Bottom splines connect to the splutch pulley. - Outer shafts top splines connect to the basket. - Bottom splines connect to the inner splines of the splutch cam. 1-5

12 Splutch The splutch is made up of five parts; a spring, housing, cam ring, basket drive gear and pulley. The pulley is connected to the agitator through the agitator shaft. The agitator always moves with the pulley. The basket drive gear is connected to the basket by the inner splines contacting the outer splines of the transmission. The cam ring raises and lowers the basket drive gear. When the basket drive gear teeth are engaged to the pulley teeth the basket will spin along with the agi. 1-6

13 Shifter / actuator The actuator serves several functions. It has a synchronous motor that shifts the splutch slider and monitors the position of the splutch. It also houses a transmission speed/position optical sensor. The shifter motor rotates a cam, attached to the shifter arm. The shifter arm moves the transmission lever which engages or disengages the transmission allowing agitate or spin. When the shifter is up in this position, the washing machine is in spin, wetting or sensing modes. The teeth of the splutch are engaged with the teeth of the pulley and the motor turns the pulley in a direction for spin. When the shifter pulls the lever down it disengages the teeth from the pulley. The washing machine is in agitate. The length of each stroke is controlled by the CCU. There are three different patterns. 1-7

15 Lid lock Since this washer does not utilize a brake, a lid lock is used to prevent access during use. During a cycle, a lid lock mechanism will lock the lid. The lid must be closed for the washer to fill, wash, drain, or spin. The lock mechanism houses a switch that senses the lid is down, a latch solenoid and a magnetic reed switch to confirm that the lid is locked. The lid lock is specially designed to give way if forced open, however, cycle will be lost without credit given. 1-9

16 Control panel and features ENERGY ADVANTAGE TOPLOAD WASHER This washer is specially designed to conserve energy and water. Each cycle, along with any selected modifiers will result in different energy and water usage. As you make your cycle, temperature, and rinse selections, energy savings will vary. Factory preset cycles will save the most energy and water. CYCLE SELECTION Use the left key pads to select cycles on the washer. Use the right key pads to select the various modifiers for laundry load types. CYCLE OPTIONS When a cycle is selected, its default settings will appear on the display. As modifiers are selected or deselected the display changes. Selecting modifiers may require upcharges, although deselecting default modifiers will not reduce changes. TEMPERATURES Temperature Control senses and maintains uniform water temperatures by regulating incoming hot and cold water. Select a wash temperature based on the type of fabric and soils being washed. For best results and following the garment label instructions, use the warmest wash water safe for the fabric. Warmandhot waterwillbecoolerthan what any previous washer type provided. Even in Cool wash, some warm water may be added to the washer to maintain a minimum temperature. CYCLE TIME The wash time is preset for each wash cycle. Selecting the various cycles will increase or decrease cycle times. Cycle times shown prior to starting a cycle usually decrease after load sensing at start of the cycle. SPIN SPEED This washer automatically selects the spin speed based on the cycle selected. The preset speeds cannot be changed. 1-10

17 CONTROL PANEL AND FEATURES (CONTINUED) SENSING When the START button is pressed, the washer will first perform a self-test on the lid lock mechanism. You will hear a click, the basket will make a slight turn, then the lid will unlock briefly before locking again. Once the lid has locked the second time, the washer will slowly spin the dry load to estimate the load size, and begin adding water. The washer will then move the load briefly, pause to allow water to soak into the load, and resume adding water. This process may repeat until the correct amount of water has been added for the load. ESTIMATED TIME REMAINING The estimated cycle time remaining changes due to several factors. Factors such as load size and water pressure may affect the cycle time. Overloading, unbalanced loads, or excessive suds may cause the washer to adjust the cycle time, as well. NOTE: The sensing light may also come on during the Soak and Wash portions of the cycle. This is normal.

74 ---- NOTES

75 DIAGNOSIS & TROUBLESHOOTING DANGER WARNING Electrical Shock Hazard Only authorized technicians should perform diagnostic voltage measurements. After performing voltage measurements, disconnect power before servicing. Failure to follow these instructions can result in death or electrical shock. Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. Voltage Measurement Safety Information When performing live voltage measurements, you must do the following: < Verify the controls are in the off position so that the appliance does not start when energized. < Allow enough space to perform the voltage measurements without obstructions. < Keep other people a safe distance away from the appliance to prevent potential injury. < Always use the proper testing equipment. < After voltage measurements, always disconnect power before servicing. Before Servicing, check the following: Make sure there is power at the wall outlet. Has a fuse blown or circuit breaker tripped? Was a regular fuse used? A time-delay fuse is required. Are both hot and cold water faucets open and water supply hoses unobstructed? All test/checks should be made with a VOM (volt-ohm-milliammeter) or DVM (digital-voltmeter) having a sensitivity of 20,000Ω per volt DC or greater. Resistance checks must be made with washer unplugged or power disconnected. IMPORTANT: Avoid using large diameter probes when checking harness connectors as the probes may damage the connectors upon insertion. Check all harnesses and connections before replacing components. Look for connectors not fully seated, broken or loose wires and terminals, or wires not pressed into connectors far enough to engage metal barbs. A potential cause of a control not functioning is corrosion or contamination on connections. Use a ohmmeter to check for continuity across suspected connections. Perform the service diagnostic tests before going to specific troubleshooting tests. (See page 5-2) 5-1
