Re: whirlpool front load washer GHW9100LW
Appreciate the "Ask Me".
My compliments that you have determined that error code F06 indicates drive motor tach error. This relates to the controller board not sensing that the motor is spinning. This could be attributed to three (3) possibilities:
motor is not really turning/stuck, a replacement is required;
motor is turning but the sensor attached to it is defective and therefore not sending signals to the controller board. Pls check the terminals/connectors/wirings; and/or
the controller board input circuitry is defective. It does not register any input from the motor's RPM sensor. This could be a diode, resistor or logic IC. This would be component level repair requiring familiarity with electronic circuitry and components, use of a DVM and a soldering iron. It wold be easier to replace the entire controller board..
In some instances, it could just be the motor's capacitor that is defective. The capacitor provides the initial kick for the motor to start running. Failure on the capacitor will not kick start hence motor will not start hence RPM sensor says to controller board motor not running.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

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 ControlUnit (MCU), and between the MCU and the Central Control Unit (CCU)
• Check the Drive Motor
• Check the MCU
• Check the Wire Harness
The F06 is a drive motor tachometer failure which means the motor control is not able to see the motor is running. This can be a difficult problem to pin down, but there are some things you can do yourself if you like. Check the connections between the motor control and motor. Also check connections on the central control are all tight. Push on all of the connections and see if there is any improvement. The images below will help with access on some Maytag front load washers.
The cause of this is the motor control (MCU) not communicating with the control board. Try unplugging the unit for 30 seconds and if this does not solve the problem replace the MCU. This is located behind the panel under the door screwed to the floor of the unit near the motor.
Drive Motor Tachometer Error. The control is unable to properly detect motor speed and the washer will shut down.If a failure occurs during high-speed spin the door will be unlocked after 3 minuts. Check wireharness connections between the drive motor/Techometer and the motor control unit also check between the motor control unit and the central control unit. Check the drive motor, the motor control unit, and wire harness.
