Question about Kenmore 46462 Front Load Washer

1 Answer

No power i have no power. i checked circuit breaker and outlet. i opened the top and i think i found the central control unit (CCU). it was a rectangular box about 3" x 5". it had a circuit board in it and a lot of wires plugged into it. it looked liked it was supposed to be mounted on the right wall, but it was dangling against tub. i found a repair manual that said check CCU by plugging in washer and listen for a click in the CCU. i heard no click. it also said to check continuity of line cord and line filter. i have a few questions. 1. was that the CCU that i found? 2. how do i check the continuity of line cord and line filter. i bought an ohmeter and never used one before. can you tell me exactly how to use the ohmeter? is there anything else you can think to check? thank you very much

Not sure about the CCU. I'm not familiar with this washer. But, when using a meter....an ohmeter is used for testing continuity of a wire. if you can touch each end of the wire with the meter probes, you should observe a low resistance (low number). If the wire is broken you would see no change on the meter (infinite ohms). You would, of course, have the cord unplugged to prevent shocking yourself whenever you have the covers off of the machine.

F01 CODE ON WHIRLPOOL MODEL# WFW8500SR00 FRONTLOAD DUET SPORT HT, ALLREADY CHANGED THE PUMP MOTOR


ERROR CODE F01
The pump driver fails to activate/One of the main relays is not working properly/
A communication error between the Central Control Unit (CCU) and the EEPROM
onboard the CCU occurred.

Check for loose power outlet. A loose power plug in the wall can create
line noise and issues.
- Check if washer is on a dedicated circuit. Other devices on same circuit
can create line noise and cause this issue.
- Unplug washer or disconnect power.
- Make sure that wire harness connections from the CCU are not broken or with wires
detached, and that connector internal pins are visible.
- Make sure all green wires (ground harness system) are not broken or detached.
- Make sure the two ground switches are pressed correctly by the toe and rear panels.
- Make sure all connectors are fully seated.
- Plug in washer or reconnect power.
- Check for power going to Central Control Unit (CCU) by listening for a click in the
CCU when unit is plugged in washer or when reconnecting power.

If no click is heard, replace the CCU. Here is the part to order.

Whirlpool duet getting error code F70 and F71. When hitting start button, getting a clicking sound and nothing is happening. Cannot open the washer door as it is locked with clothing inside it.


Hi jreib29,

F70 and F71 are two logic board error codes that point at a communication error between the main logic module and the control pad (user interface and CCU), and between the motor control unit and central control (MCU, andd CCU that is main control module).
Repair is difficult, as motor, wiring and voltages from control modules must be tested.

Try first doing a reset, by disconnecting power cord or tripping circuit breaker and leaving power off for five minutes.

If that does not help and errors come back, then the best thing to do is calling the service number listed on the user manual.

Here extensive explanation of error codes and relative troubleshooting:

F70: CENTRAL CONTROL UNIT HEARTBEAT FAILURE
If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the Central Control Unit to the User Interface.

1. Check for continuity of the User Interface harness.
2. Check wire harness connections to the User Interface and the Central Control Unit.
3. Replace User Interface if drum is rotating.
4. Replace Central Control Unit if drum is not moving

F71: USER INTERFACE HEARTBEAT FAILURE
If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the User Interface to the Central Control Unit.

1. Check for continuity of the User Interface harness.
2. Check wire harness connections to the User Interface and the Central Control Unit.
3. Replace User Interface if drum is rotating.
4. Replace Central Control Unit if drum is not moving.


Hope this helps.

Thank you for using FixYa.

    Washing machine will not turn on. yes i checked the outlet


    Make sure that the outlet is working even though the breaker is okay. Plug a small lamp or appliance into the washer outlet to verify that it is working.

    If the outlet apparently has power the plug the washer back in and listen carefully for a click from the CCU (Central Control Unit or main control board shown in the first image below). If you do not hear a click then I recommend that you unplug the washer and remove the top panel (shown in the first image below). Check the wiring harness connections on the control board. I provided a wiring diagram in the second image that shows the path of power to the CCU. If you have a volt/ohm meter and the technical expertise, you can check the continuity of the power supply to the control board (wires traced in red and green on wiring diagram below). If the CCU is apparently getting power but does not click shortly after it is plugged in then it will need to be replaced.

    You could also have a failed user interface touchpad assembly that would prevent the washer from powering up.

    These tips may help you determine the cause of this washer failure.

    Error code F11


    F11 is an indication of a communications problem.
    Communications cannot be sent correctly between the machine control board and the motor control board.
    Here are some possible causes:
    • Loose wire connection at either the machine control board or motor control board.
    • Machine control board failure
    • Motor control board failure
    • Door lock
    • Motor
    Error codes can be caused by a Power Surge or other electrical anomaly, attempt to return the washer to operation by following the Hard Reset procedure below.

    In some cases the control can be non-functioning or may not accept activation from the control panel. To clear and restart the control follow the these steps:
    1. Unplug or turn the circuit breaker off for 10-20 minutes.
    2. Reconnect the unit to the power source by turning the breaker back on or plugging the unit back into the wall outlet.
    3. Press the Pause/Cancel/Stop button twice to clear the display.
    4. Start a short cycle to check the operation of the machine by selecting a cycle and pressing and holding the start button until the machine starts.

    What does code F70 and F71 mean on my whirlpool duet?


    Error code F70 means no communication is detected from the Central Control Unit (CCU) to the User Interface while F71 is the reverse; no communication detected from the User Interface to the Central Control Unit (CCU). This could simply mean a loose or poor connection between the two communicating boards.

    Disconnect power to the washer prior to servicing to avoid the risk of electric shock.

    Remove the three screws attaching the top panel to the rear of the washer then slide the panel rearward and lift it off the washer.

    Disconnect the User Interface ribbon connector from the left side of the Central Control Unit (CCU) and clean the connector and terminals thoroughly. Reseat the connector several times to ensure a good connection between the Central Control Unit (CCU) and the User Interface.

    It is highly recommended to clean and reseat every wiring harness connector from the Central Control Unit (CCU) to prevent the same problem in the near future.

    Reconnect every wiring harness to the CCU and make sure all connectors are firmly seated. Slide the top panel back into position and secure it to the rear of the washer with the screws previously removed.

    Let us know if the problem persists for further assistance. We will be happy to resolve your problem.
