Whirlpool wtw6400sw0 washer-already replaced control module and user interface, still spins unbalanced, can I reset it somehow or calibrate it?

WHIRLPOOL CABRIO WASHER ERROR F2

The Cabrio Washer F2 error happens when the main control detects a stuck key on the user interface. The steps to take to try and fix the F2 code problem are below:

Unplug the washer for five minutes and then plug it back in, this will reset the control board.
If the persists then the only way to fix it is to replace the user interface board.

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.

Hi


Thanks for using FixYa. Error F70 is 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. To resolve this issue you’ll have to:

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


Please do rate the solution if the issue is resolved or post a comment for further assistance.

Hi,

F70 error code indicates 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


Thank you !!

Hi


Thanks for using FixYa. Error F70 and F71 indicate no communication between the Central control unit and the user interface. To start with you’ll need to check continuity of the user interface harness and also check the wire harness connections. You can also try to rotate the drum, if the drum is rotating the User Interface should be replaced and if it wont move then the Central Control Unit should be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.

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.

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.

did u replace both boards the machine control and user interface

hi there,

Most noises from a washing machine occur during the spin cycle. If you hear loud thumping/or sound
during the spin, the load of clothes may have become unbalanced. Stop the washer and
redistribute the clothes, then re-start it. Repeat these steps if necessary.
