this is a duet correct? usually there is another # XXXXX letter after the F is there?
Customer: replied 7 years ago.
I think it was the # XXXXX My wife would know but she's at the laundry mat finishing the load that failed.
Customer: replied 7 years ago.

Wife is back and yes it is F 6.

I'm not sure what a duet is. It is a single washing machine, not a dual washer/dryer.




Customer: replied 7 years ago.

Any response? How can I avoid getting the F 6 signal?


What should I do to avoid the F 6 signal?


Do I need to call a repair man?


Thank you,

this it the closes I can find on yours,

Drive Motor Tachometer Error

The control is unable to properly detect motor speed and the machine will shut down. If a failure occurs during high-speed spin, the door will be unlocked after 3 minutes.

  • Check wire harness connections between the Drive Motor/Tachometer and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU)
  • Check the Drive Motor
  • Check the MCU
  • Check the Wire Harness
you may need to call for service on this. these are complicated machines and need a tech to test them.
