Product review (5 stars): Little sensor did the trick!
My 4-5 years old front loading LG washer suddenly showed "LE" error code and stopped spinning after 4-5 min.
Tried manually spinning the drum 5 times clockwise 5 times counter-clockwise, hard reset process few times but the same error code appeared after 4-5 min and stopped spinning. I think this is fairly common problem (due to non-stop use or non HE detergent, cheap detergent, etc.)

Google + Youtube searched and found out that this little sensor might be bad.
Called LG & explained the problem and they estimated the cost $250 for in-home repair.
My manual/warranty showed that the parts are still under warranty but that's basically in-home labor charge.

So I give it a shot and ordered the part as DIY repair seems to be fairly simple if you know how to use screw driver & ratchet.
It took me about 15-20 min. to replace & complete the work.
Getting behind the washer was harder than actual repair.
My LG washer is back working fine.
