This unit does not agitate or spin. Customer reported it quit running a week ago. Says it showed a F6 code, although when I was there it never did. The washer will fill & drain but will not agitate or spin. Tub will spin manually easy. Disconnected & reconnected harness wiring a couple of times. Examined for corrosion, non evident. Pulled MCU out & examined, no sign of trouble.
Put in diagnostic using a tech sheet from a similar model. ie. Drain/spin. no spin & prewash option 4 times. No motor movement. Checked motor pins 1-3,2-3,1-3, all have 8 ohms. All I have researched says motor control. What can I check to eliminate motor, MCU, and/or main control board?
