Hall sensor failure:
When too much of the low-sudsing HE detergent is used in the LG washers (and especially non-HE type detergent)...
The motor & main board will detect suds when the tub begins to spin.
As strange as this sounds--suds causes drag/resistance.
The older hall sensors overheated--the main board would shut-down the washer & flash an error message of "LE".
If the Hall Sensor was not damaged--then the customer would be able to unplug the washer for about 2-3 minutes and plug in the washer again--the washer would be able to be re-started (reboot of the computer).
Eventually--this results in an "LE" error that won't re-set and the Hall Sensor needs to be replaced. The tell-tale symptom of this (aside from a "stuck" LE error) is that when the customer pushes the START button--the tub *wiggles* momentarily before flashing LE again.
On a few occassions--the washer WILL start but the motor GROWLS loudly.
An occasional LE error but always a slow or no spin: Solution:
The Red wire going to the Hall sensor was intermittent. You can test this from the main board connector down to the connector on the hall sensor by checking continuity. There is an intermediate connector down by the motor/hall sensor so you can isolate the problem even more. My problem was in the short wire harness that connects directly to the motor and hall sensor. I could not find the open point of the wire so I added a new red wire and integrated it into the harness.
