Product review (5 stars): Fix it yourself
Too, too long we've been scared to address the issues inside these appliances we depend on.  I too was afraid of what lie beyond the back access panel on our LG washer.  After we were quoted $485 to fix ours, I decided to look it up.  A quick Google investigation led me here.

The part arrived just 3 days after ordering on standard shipping.  I rushed into the garage with my trusty iPad in tow.  There's a YouTube video showing how to replace this little guy.  Aside from the the main bolt holding the rotor on, this is remarkably simple.  Tip:  you'll need a rubber mallet).

So if you're getting the infamous LE error, just buy this.  Do it yourself.  You'll be glad you did.
