Kenmore HE4t Washer 110.45091 400

Hello all,  looking for diagnostic help, my Kenmore HE4t washer, it will freeze mid cycle flash a F6 code briefly and then just shut down.  It will restart only after being unplugged for at least a 1/2 hour, but sometimes we have to unplug/plug several time before it will finally complete the wash cycle. 

Suggestions???

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.
Potential Causes
• 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

There should be a tech sheet on that unit. Pull off the bottom panel and check inside the panel. It is usually taped inside the panel.

Thank you for your help,  The Tech sheet seems to be missing, can one be found on line?
