    Thanks gents,

    I did call and the service man will be out monday. Strange that they don't put the error codes in the trouble shooting section of the manual. The "tech" that I talked to wasn't sure but suspected it was the main controller. I hope this failure isn't a sign of the future for this product.

When you open up your washing machine, taped to the inside of one of the sides will be a plastic sheet, with a detailed list of troubleshooting problems/solutions, and all the codes for that particular model.

This indicates a problem with the main controller. You can try unplugging for 30 minutes then plug back in. If you continue to have issues, call for service as this machine is under full warranty if less than 1YR old..

Ok when the machine is less than one year the warranty is still in effect. Please contact Kenmore prior to opening up the machine as it will void the warranty.

Whirlpool duet F70 and F71 error codes.


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.

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.

Error code f70


Hi,

F70 Error code means 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.

F71 error code meansUser 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.

In both the above situations the following things are required to be checked and replaced where required:

1. Continuity of the User Interface harness.
2. 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.

Flashing code F71 then F70


We've owned a Whirlpool Duet Washer (WFW9200SQ00) for about 3 years. We started getting the F70 error code intermittently about 6 months ago and it seems to progressively be getting worse. Unplugging the unit for a few minutes resets the error, but it comes back about every 2nd or 3rd load causing my wife a lot of frustration and with 4 kids, our laundry was backing up. After reading several Forum's, I found the F70 error code indicates a "heartbeat" communication error between the various electronic boards inside the washer and the consensus seems to be the most likely culprit is the Motor Control Unit (MCU) board. Before spending nearly $250 for a replacement board (http://www.helpfulparts.com/servlet/the-5733/8183196/Detail) with no guarantee that it would fix the problem, I decided to take the board out of the machine and inspect it. What I found is the connector for the communication (the connector with three blue wires) on this board is a very unreliable connector that uses the edge of the printed circuit board on one side of the connection instead of a real connector soldered to the board. In addition, the fit of this connector seems to loose to make a good connection. I noticed a little bit of corrosion on the board contacts which I cleaned with rubbing alcohol and a pencil eraser. After re-installing the cleaned board we've done several loads with (keeping my fingers crossed) no errors. I am still concerned about the reliability of this connection. Because of it's location, this board is subject to a fair amount of vibration and because of the loose fit I'm concerned that this issue will only come back over time. I've already decided that if the error comes back I will solder wires to the contacts on the board to provide a more robust connection. It's a shame that you can spend well over $1,000 on a top of the line washer, and in order to save $.10 Whirlpool decided to use a very poor connector in a critical area. It makes you wonder where else did they skimp to save a few pennies?!! Our next washer will not be a Whirlpool, and next time will not get a high end washer with all the bells and whistles.
