    Still working on that washer--I did replace the ccu board but washer still wouldn,t start--just



    beeped when power button pushed.Waiting on motor board now--I believe itmust have shorted out



    but has no signs of burnt marks. I,ll let you know after I try the motor board. Rene


  • Rene Matz Sep 05, 2010

    Didn,t get that washer up & running until I replaced the motor board.The F71 error code did



    refer to problem with interface or ccu boards--but in this case(maybe because of water) although



    washer was suppose to have worked for awhile-- problem went farther.



    Thanks again. Rene

The F71 error code indicates a user interface heartbeat failure.

F71 error codes on this model of washer indicates a communication problem between the user interface control board and the central control unit (main control board). These error codes can sometimes be caused by a power surge or glitch through the electrical lines. Try unplugging the washer to completely disconnect electrical power. Wait 1 minute and then plug the washer back in to the see if the fault code clears. If it does, then the washer may work normally.

If the code reappears, then you could have a wire harness connection problem, a failed user interface control board or a failed central control unit.

    Yes--I,m leaning towards the ccu board. I ordered the interface board but it didn,t get
    the washer running.Late this afternoon I ordered a ccu board.Hope that one gets the
    washer back working. Thanks. Rene

I have a Kenmore model 11049962603 that displayed an f-71 error code. I ordered a new cpu computer from sears and installed it. the machine seemed to work for one or two loads. now it displays an f-70...


I provided a complete list of error codes for this type of washer in the image below. The error codes vary by the exact model of HE3t washer that you have. Since you have an HE3t that is displaying the F70 and F71 codes, the list below should apply to your model. These are not listed in the owner's manual because they are intended for technicians. Use extreme caution if you follow any of the troubleshooting described in this information sheet. Unplug the washer and shut off the water supply before accessing internal components.

The F70 and F71 codes indicate that you have a communication error between the CCU (Central Control Unit or main machine control board) and the user interface touch pad assembly. Here are some troubleshooting tips:

Make sure that you have the washer plugged into a properly grounded 3 prong 120 volt AC electrical outlet.

Unplug the washer for 30 seconds to allow the control boards to power down and reset. Plug the washer back in but do not touch the power button (or any other buttons) for 1 full minute. This may reset the control board. Pressing the power button too quickly after reapplying electrical power to the washer can cause the F70 or F71 code since the CCU does not have time to recognize the user interface control.

If the above tip does not help then the most suspect component failure is the MCU (motor control unit -- motor control board at the bottom of the washer beside the drive motor). You can check for this failure by unplugging the washer and then pulling the MI3 connection on the CCU. The wiring diagram below has the MI3 connection highlighted in red. The connection has blue wires. The third image below shows this connection on the control board. The connections are labeled on the control board. Press the tab at the bottom of this plug down and then pull it out. Power up the machine with this connection unplugged and don't touch any buttons for 1 minute. If you then press the power button to turn on the washer and don't get the F70 or F71 code then the MCU at the bottom of the washer will likely need to be replaced to fix this problem. A technician would normally be needed to verify this failure and replace the MCU. The MCU is expensive ($423).

This troubleshooting information is based on a common HE3t model that displays the F70 and F71 codes. If you need more help, submit additional details and the full model number of your HE3t washer.

He5t washer keeps flashing F71.


The F71 and F70 are difficult error codes to pin down even for a technician.
The F71 indicates a user interface heartbeat error while the F70 indicates a heartbeat error in the central control.
There is a quick test you can try to resolve the problem. 1. Lock the control by pressing and holding the cycle signal button. 2). Press the Power button.
3). If the lock light flashes when you press the power button it indicates the center interface was able to take the input and the Right hand User Interface received the DCV signal from the Center User Interface but since the display did not light. This indicates an issue with the Right hand user Interface.

Be sure your unit is plugged into a 3 prong grounded outlet as well.


F71 is a "heatbeat failure" which means that your front interface control board is shorted and will need to be replaced. it's actually fairly easy to replace and can definitely be done by yourself. To access the part, just pull the unit forward and remove the 3 screws coming in from the back of the top panel. Remove the top panel by pulling it back, up, and off. Then remove all the screws going into the top of the control panel. Remove the dispenser drawer and remove the screws coming in through the dispenser. Remove the screws coming from the inside of the dryer going forward into the control panel, then remove the control panel (it's just clipped in on the bottom. After that you can disconnect the wire harnesses to the front interface control board and replace that part.

No communication between UI and CCU


Hi.

I think that by this time you already fixed the problem. The codes indicate usually a fault that is either CCU or MCU.

Please read the tip below, explaining how to fix F70 and F71 problems. The comment applies to Whirlpool built kenmore washers like the one in question.

F70 and F71 are two logic board error codes that point at a communication error between the main log...
