<<<Yesterday I was doing a wash and received an LE error that I can not get rid of on my LG WM2277WH Tromm Washer.>>>
<<<I also used almost a full cap of HE detergent. From what I've recently read, only a small amount of HE detergent should be used. Using too much, even if HE can fault the Hall Assembly (or this one in particular)?>>>
The original HALL EFFECT SENSOR on the LG WM2277 washer---can (and will) be damaged from using non-HE detergent or too much of the correct type of detergent.
Replace the HALL EFFECT SENSOR (6501KW2002A
All replacement/re-designed Hall Effect Sensors are stronger/better than the original---and will likely never fail again.
Install a new Motor Wire Harness (6877ER1016B
)---as these are prone to developing cracks within the wiring---from years of motion/movement.
<<<My other concern is there is a louder whining noise when spinning than previously. I am hoping it is not something else wrong since it was a heavy load.>>>
When Hall Effect Sensors fail---it can be an intermittent-type of failure (the washer may function---then quit/stop before completing a cycle).
If the Hall Effect Sensor has partially "burned-out"---then the motor can make a loud Growl/Grinding/Whining noise.
Prior to the "LE" error---if your washer had *not* been noisy (whine)---then the Hall Effect Sensor is the cause/fault for the noise symptom as well.
