Product review (5 stars): Does the trick
Needed this after 6 years of using the washer daily.  Took out the old unit to see if I could repair it, but this old unit had no visible problems.  Put the new unit in and the washer has been working fine.  PS: you don't need the $75 special LG spanner pliers to remove the gasket hold-down spring.  It is a bear, but you can pry that spring off and pry it back on; also, it helps to have a helper do this with you.
