LG Front Load Washer Model# WM3050CW LE Error

[DrivenYFZ]

I am getting the LE error and replaced the wiring harness and the hall sensor.  I checked both after they were replaced via the fixitnow.com site.  Everything checked out good on the new parts except the output signal on the hall sensor.  I could not get it to give me a pulsing 10vdc when I turned the drum by hand.  Is it likely that my new hall sensor is bad also or could there be something that is causing it to go bad?  Initially when I was diagnosing the error I kept seeing the Load Size indicator and it really wouldn't do much of anything before giving the error.  Also there was water in the drum from when it errored out.   After replacing the sensor and harness I ran a tub clean and it did not show the Load Size indicator and seamed like it was starting to work but when it tried to turn the drum a couple of times it seemed to have a lot of vibration.  It added more water in and then when it tried to start the drum again it did a very quick vibration and immediately stopped the threw the LE code again.  I tried turning the drum with a drill on the back bolt and it turns freely with no rubbing or vibration issues.  I am an electrician by trade so good with a volt meter but I'm not an electronics major to put it nicely!  

Is it likely I got a new bad Hall sensor?  Does it happen that the input on the hall sensor is good but output is bad?  Any help or direction would be greatly appreciated!

 

Thanks,

Just to verify parts  wire harness 6877er1016f and sensor 6501kw2002a. Have you check the rotor of cracked magnets ? Have you ohmed out the windings of the stator?  If those are all good then check the both wire harnesses  - ohm the from the main control board to the rotor and sensor.  Flex the short wire harness ( one from the stator/ sensor to the frame). This diagram should help:

Thank you, I did ohm out the stator but didn't check it for cracks.  I am wondering if its is something in the wiring on the main harness.  I removed the tape on it and was just sort of checking it out, I plugged everything back in and just made sure all connections where solid and then ran another tub clean.  it still triggered the load size which I thought was odd but it worked.  We have now run two tub cleans and two loads of laundry and everything seems to be working right.  I hate not knowing exactly what it was but as long as its working I guess I won't complain!!!!  Thanks for the suggestions!
