FOR SERVICE TECHNICIAN'S USE ONLY  If indicators come on, select one of the "Timed Cycles" (for example, "Timed Dry"). If either the "+" button or "-" button is unable to change the time indication in the Estimated Time Remaining three- or two-digit display, something is faulty with the button, and it will not be possible to enter the Loads Test mode. Replace the user interface and housing assembly. Refer to Dryer Disassembly Instructions, page 24. If the "+" and "-" buttons both work, press the POWER button to turn off the dryer and retry to activate Loads Test mode from step 1 above.  If no indicators come on after selecting the cycle, go to TEST #1, CCU Power Check, page 11. Indication 2: Console indicators begin flashing immediately. Action: If console indicators begin flashing on and off immediately, replace the user interface. Activation with Saved Fault Codes If there is a saved fault code, it will be flashing in the display. Review the Fault/Error Codes table on page 9 for the recommended procedure. If there is no saved fault code, "888" or "88" will be displayed. NOTE: Entering into Loads Test mode may automatically reset some codes that may have been set, and that information could be erased. Before activating the Loads Test mode, be sure to check for Saved Fault Codes using the Service Diagnostics mode; see procedure on page 4. 1. DIAGNOSTIC: Console Buttons and Indicators Pressing each button will turn off its corresponding indicator(s) or display segment and sound a beep (see figure 1a or 1b, page 2 or 3). On some models, rotating the cycle selector knob turns off each corresponding cycle indicator. NOTE: A second press of the POWER button exits the mode and returns the dryer to standby mode.  If indicators do not turn off and beep after pressing buttons and, on some models, rotating the cycle selector knob, go to TEST #6: Buttons and Indicators, page 21. 2. DIAGNOSTIC: Console ID, Motor, Heater, and Water Valve Make sure the door is closed, and then press the START button. The dryer will beep and the motor, heater, and water valve (on some models) will turn on. The console ID will be displayed on the LED ("097", "095", "092", or "090" on three-digit display models, "87", "83", "8 1 ", "75", "75...50", or "72" on twodigit display models). Opening the door stops the motor, heater, and water valve (on some models).  If the Console ID is not displayed, replace the user interface and housing assembly.  If the motor does not turn on, go to TEST #3: Motor Circuit, page 14.  If no heat is detected, go to TEST #4: Heat System, page 15.  If no water is detected, go to TEST #9: Water Valve, page 22. 3. DIAGNOSTIC: Door Switch/Drum LED Opening the door should display "eee" or "ee" (electric), "999" or "99" (gas) and turn on the drum light (on some models). Closing the door should turn off the drum light (on some models).  If opening the door does not cause "eee" or "ee" (electric), "999" or "99" (gas) to be displayed, go to TEST #7: Door Switch, page 21.  If opening the door does not turn on the drum light (on some models), go to TEST #8: Drum LED, page 22. 4. DIAGNOSTIC: Moisture Sensor Open the door and locate two metal strips on the face of the lint screen housing. Bridge these strips with a wet cloth or a finger.  If a repeating beep is heard and an alphanumeric number is displayed on the console, the sensor is good.  If not, or if a repeating beep tone is heard before bridging the moisture strips, go to TEST #5: Moisture Sensor, page 20. Exit Procedure To exit Loads Test, press the POWER button once or twice (depending on diagnostic procedure). PAGE 6 DO NOT REMOVE OR DESTROY
