Hello Carol;

My name is Peter. I am a retired field service appliance technician.

F70:

No communication between the electronic control board and the user interface control board assemblies.

Unplug the dryer. Check the wire harness connections between the main electronic control board and the user interface control board assemblies. If the connections are sound, have a technician diagnose the cause of the communication failure. The main electronic control board and/or the user interface control assemblies might need to be replaced.

On Whirlpool duet steam front loading DRYER...What does the error code F70 mean?Do you have to have a certified whirlpool appliance service professional to repair?


F70 code says...
Replace the machine control electronics. You should first unplug the machine and then remove and plug back in all connectors on the front panel model as well as the electronic control module.

If that doesn't take care of the problem then it may be time to consider replacing the rear board. The FSP # 8183259

The control board is part # 14 in the link below.

F70 was displayed on Whirlpool duet dryer what does F 70 mean


Isnt F70, really is F07... this means Motor Control Unit Error
Description: The Central Control Unit has detected a short in the motor control unit. If a failure occurs during high-speed spin, the door will be unlocked after 3 minutes.

Check or Repais:
- Check wire harness connections between the Drive Motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU)

- Check the Drive Motor
- Check the Wire Harness

Hope helps.

What does F70 flashing mean?


The F70 is an internal control problem. It can be caused by a failed central control board or an interface problem. The way to determine which part is bad when the error occurs is as follows:

  • If the error occurs when the machine is running then the problem is the interface.
  • If the error occurs when the washer is not running the problem is the central control unit.

My Dryer Kenmore Elite HE5 show the Code F70...


The F70 and 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. I recommend calling a service technician to properly diagnose and repair this type of problem so that the correct component can be replaced.


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.

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.

What does the code f70 on a kenmore elite dryer mean?


F70 is a "communications error" message and the first thing to check is loose wire connections.

If a loose connection is not found, the controller board will probably need to be replaced.

Please report back here what you find, OK?
