  1 Washer Tech Data Sheet T his information is intended for Qualified Technicians Only. CAUTION: DISCONNECT ELECTRICAL CURRENT BEFORE SERVICING Please Return This Sheet to its Envelope in the Product for Future Reference Contents Page Error code explanation........................................1-2Diagnostics ....................................................... ....2Error Code Chart.............................................. .....3Tests................................................................ ...4-5Françis.............................................................. 6-10Wiring diagram......................................................11The electronic controls of the 3.0 Cu. Ft. horizontal axis washers have self diagnostics codes built in that cover most productsfailures. Model differences: ã Better models have a digital readout display ã Good models do not have a digital readout displayIn the Better Models line, the failure codes will appear in the display as an E followed by two numbers, a number and a letter or two letters. The control will beep and the Door Lock, Wash, Rinse, Final Spin and Control indicator lights will flash.Example: E14 . To stop the flashing and beeping, the customer may touch the Pause Cancel button. The error code remainsstored in the control but once the problem is corrected, it does not effect the operation of the washer. If the failure is somethingthat the customer can correct (such as the water faucets being turned off), the washer will operate normally the next time it isstarted.In the Good Models line, the control signals the failure code by flashing the five indicator lights of Door Lock, Wash, Rinse,Final Spin and Control for the first number or letter after the E and the Start indicator light for the second number or letter after the E. When a failure occurs, the washer stops or pauses and the control beeps and flashes the five indicator lights to tellthe customer that a failure has occurred. To stop the flashing and beeping, the customer may touch the Pause Cancel button.The error code remains stored in the control but once the problem is corrected, it does not effect the operation of the washer.If the failure is something that the customer can correct (such as the water faucets being turned off), the washer will operatenormally the next time it is started.To recall an error code, ã Wake the machine by pressing any button ã Wait 5 seconds ã Press and hold the Start and Pause Cancel buttons simultaneously ã  All LEDs will go blank and after a few seconds the control will signal the stored code using audible beeps and blinkingLEDs. The control will repeatedly signal the code, as long as the Start and Pause Cancel  buttons are pressed. A two-second pause between repeats affords you the ability to make accurate counts to identify the correct error codes.Please Note the following...... on a small number of washers with serial number prefix XC4, if the previous procedure does not perform as specified, follow the option below: ã Follow all previous steps but instead of pressing Start  and Pause Cancel  buttons,press and hold  Options and Pause Cancel  buttons.If the washer is a Better Model, the error code will appear in the display. Troubleshoot problem by using charts on thefollowing pages.If the washer is a Good Model, the five indicator lights of Door Lock, Wash, Rinse, Final Spin and Control will flash thenumber of times for the first digit of the code and the Start indicator light will flash the number of times for the second digit.Take separate counts of each indicator light, then repeat to confirm in order to be accurate in identifying the proper error code.The code is obtained by counting the number of times the lights flash. Example E24: The five indicator lights would flash twiceindicating the 2 and the START  indicator light will flash four times indicating the 4. The five indicator lights and the START indicator light start flashing at the same time.The control will pause for 2 seconds, then repeat the code as long as the two buttons are pressed and held. Note:A letter appearing in the code standsfor a number higher than nine: A = 10B = 11C = 12D = 13E = 14F = 15 Example Code F1: the first digit would be 15 and the second digit would be 1. If this code would appear on a washer in the Good  model line, the five indicator lights would blink fifteen times and the START  indicator light would blink once. Troubleshootproblem by using charts on the following pages. Quick Check If there is no error displayed and the washer momentarily starts then turns back off:1. Listen for a relay closure inside the motor control shortly after the START  key is pressed. If this happens, themotor control has power.2. Check the 5 pin connector wiring between the console control and the motor control.  P/N 134408500  2 Examples: Identifying Error Codes on non-digital display models: The following LED Flashes and Beeps signal E41 (Error code  41 ) Door Open COUNT>>>>>> 123456789ABCDEF1st Code Digit5 Vertical LED Flashes XXXX 2nd Code DigitStart LED Flashes X The following LED Flashes and Beeps signal E14 (Error code 14 ) Reed Switch COUNT>>>>>> 123456789ABCDEF1st Code Digit5 Vertical LED Flashes X 2nd Code DigitStart LED Flashes XXXX The following LED Flashes and Beeps signal EF1 (Error code F1 ) Clogged Pump 123456789101112131415 COUNT>>>>>> 123456789ABCDEF1st Code Digit5 Vertical LED Flashes XXXXXXXXXXXXXXX 2nd Code DigitStart LED Flashes X Diagnostic Test: The diagnostic test is performed by using the Program Knob. To START THE TEST: ã On non-digital display models, turn the Program Knob  to start position, Drain/Spin. ã On digital display models, turn the ProgramKnob  to start position, Touch Up. (NOTE: If the   model has a timer dial thatcan be rotated 360°, turn the Program Knob  to start position, Drain/Spin. ã Press Pause Cancel  to turn off LEDs. ã Within 5 seconds, press and hold the Option  and Pause Cancel  buttons until LEDs start sequentially chasing, thenrelease buttons.1. All the LEDs will sequentially light. Pressing a button below a light cluster will light all the LEDs in that cluster at one timeto confirm functionality. 2.Turn the program knob (1) click clockwise from the start position. The hot water solenoid will activate and hot water should enter through the detergent compartment.3.Turn the program knob (2) clicks from the start position. The bleach water solenoid will activate and cold water shouldenter through the bleach compartment.4.Turn the program knob (3) clicks from the start position. The bleach and the wash water solenoids will activate and coldwater should enter through the softener compartment.5.Turn the program knob (4) clicks from the start position. The door lock solenoid will activate.6.Turn the program knob (5) clicks from the start position. The door lock solenoid will deactivate and the loading door canbe opened.7.Turn the program knob (6) clicks from the start position. The washer will fill and tumble.8.Turn the program knob (7) clicks from the start position. The washer will fill and spin (leakage test).9.Turn the program knob (8) clicks from the start position. The drain pump and door lock solenoid will activate and thewasher will operate in high spin. SAFETY WARNING:  If power is removed during thistest, the door can be opened. Toprevent injury, DO NOT put your hands inside when the tub is rotating.10.Turn the program knob (9) clicks from the start position. The control will signal the last error code. Exiting Diagnostic Mode There are two options for exiting the Diagnostic Test mode and returning the washer to normal operation:a) Unplug the power cord, wait 5-8 seconds, then reconnect the power cord OR b) Turn the program knob clockwise 2 or 3 clicks after the Start Position. Press Options  and Pause Cancel  buttons together for a few seconds until wash cycle LEDs appear. If a situation arises where you cannot exit the Diagnostic mode as described above and the bank of 5 LED’s on theright end remain ON regardless of Program Knob position, a combination of pushed buttons may have caused thecontrol to enter a special factory test mode. Disconnect power to reset the control to return washer to normaloperation is this occurs.To clear latest stored error code: Place the control into Diagnostic test Mode. ã Turn the program knob clockwise 9 clicks from the Start Position. The control will signal the last error code. ã Press and hold the Options and Pause Cancel  buttons for 3 seconds. The code will be cleared. ã Exit Diagnostic Mode to return the washer to normaloperation.  P/N 134408500  3 Error code chart  Error codeFault conditionCheck E11Fill time too long.Refer to test (1).E13Water leak in tub or air leak in air bell.Refer to test (2).E14Reed switch.Refer to test (3).E21Water not pumping out fast enough.Refer to test (4).E23Drain pump relay on control board failed.Replace control board.E24Drain pump relay on control board failed.Replace control board.E31Better models.
