FOR SERVICE TECHNICIAN'S USE ONLY INSTALL DIAGNOSTICS NOTE: The Service Diagnostic mode must be activated before entering Install Diagnostics; see procedure on page 4. NOTE: If, at any point, the user presses the POWER button or opens the door during Install Diagnostics, the dryer exits to standby mode. NOTE: Door must be closed to perform test. Dryer must be cool before test to run correctly. Active Fault Code Display in Install Diagnostics If the display begins flashing while in Install Diagnostics, it is displaying an active fault code. Active fault codes are codes that are currently detected. Only one active fault code can be displayed at a time. Entry Procedure To enter Install Diagnostics, press and release the 2nd button used to activate the Service Diagnostic mode. All LEDs turn off and the START button begins to flash. WATER-ONLY TEST: Press and hold the START button for 5 seconds to run only the water system test. PERFORM ALL TESTS: Press and release the START button to run ALL tests indicated in the chart below. Exit Procedure When test is complete, press the POWER button to exit Install Diagnostics and return to standby mode. INSTALL DIAGNOSTICS STEP TEST TEST DRYER FUNCTION COMPONENT NOTES 1 L Dryer starts L2 detection algorithm. Motor On Display shows "- - -" or "- -" until voltage is available at UI. 1 • If Electric: Displays L2 level (range 2 L L2 detection complete. 2 Motor On 0 to 200). • If Gas: Displays "9as" or "9s" for gas D since L2 does not exist. & E 3 T Dryer starts L1 detection algorithm. Motor On L E Airflow detection starts at this step. Heater On L2 (electric), "9as" or "9s" (gas) continues to be displayed. 4 1 C T t L1 detection complete. CCU calculates L1 to L2. Motor On Once L1 is calculated, L1 to L2 is Heater On/Off immediately calculated in the CCU. o • L1 voltage should be 120 VAC ± 10%. 5 A I R L 2 Press the START button to cycle through L1, L2, and L1 to L2. Motor On Heater On/Off • L2 voltage should be 120 VAC ± 10%, "9as" or "9s" if gas dryer. • L1 to L2 voltage should be 240* VAC F ± 10%, "9as" or "9s" if gas dryer. L O 6 W Airflow test near completion. Motor On The display will count down the final 15 Heater On/Off seconds of the AirFlow detection routine. When the airflow routine is complete, the seven-segment display will show 7 Airflow detection complete. Motor On Heater Off airflow result (0=BAD, 1=GOOD, 2=INVALID). Also, Dryness Level will display results (Less=Bad, More=Good, Nothing=Invalid). 8 W A T 9 E R Press the START button to begin water system test. *Water Valve On Display shows "h28" or "-s" when *Drum Light On running. Steam test running. LED drum light *Water Valve On Water and LED drum light are actuated and water turn on. *Drum Light On for 30 seconds. NOTE: At any time during the test, press and hold the START button for 5 seconds to jump to the water system test. Voltages are displayed in "hex" code. Please refer to the table on page 29 for decoding. Electric dryer performance is optimized for 2-phase, 240 VAC service. If complaint is made regarding electric dryer performance and the L1 to L2 voltage is ~208 VAC, dryer may be connected to a 3-phase service with reduced wattage that will decrease dryer performance. * If equipped.
