Product review (5 stars): That Laundry Pile was getting big when that "OE" error code appeared. Luckily, it was an easy job for the do it yourselfer.
Perfect fit. If you buy it from Amazon, it's a genuine LG part. I had the dreaded "OE" drain pump warning, and this cured it.

It was an easy fix. I had a stacked washer, but you don't have to unstack them to get this out, you just have to slide the dryer back a few inches, and then you can take the front off the washer. It took me about one hour.
