Kenmore FL washer F6 error code

6 posts in this topic

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?

Look for 120 volts between the two pink wires at the MCU ... and check for 5 volts DC between the two outside blue wires on the MCU.  Also check the wire harness between the MCU and the motor ... if all test good, then it looks like a MCU to me.

2 weeks later with MCU in hand, I swap them out & fire up machine in a drain & spin mode.  Then put into a diagnostic mode.  Ran just fine as if nothing was ever wrong.  Final test run a normal cycle with a heavy load of jeans.  Happy, happy, Lady.     Oh and i sold a surge protector recommended by the big one.   Happy, happy Patricio.   An Appliantology Sensei repair & a Blue Book compensation.   I love my job.     :thanks:
