It appears your timer/main controller/CCU has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

SOURCE: whirlpool wtw6400sw0 washer-already replaced

Please see the following Whirlpool installation and maintenance PDF on Cabrio washers. An F1 relates to a "primary control failure".

It also has a very extensive troubleshooting section.

SOURCE: How do I know which

Hi

F71 is a communication error and is displayed when there is no communication from the User Interface to the Central Control Unit. First check the user interface harness for continuity and then check the wire harness to the user interface and CCU. If the drum rotates then replace the user interface, if the drum is not moving then replace the central control unit (CCU). Hope this helps...please post back for further assistance.

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.

Code f 71
Check to see whether the laundry drum to the washer moves. If it does move, then the user interface needs replacing. If the drum is locked and will not move, you need to replace the central control unit on the washer.

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.

F71 code on whirlpool duet front loader washer
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.
