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.

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 means 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.

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.

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.
