Product review (5 stars): works good as new!
This completely fixed my WM3987HW washer dryer combo machine getting error code De or Oe and not finishing the cycle.

Just something to watch out for though, This pump works so much better than the pump which failed, that my wall-drain wasn't up to the task anymore and I had to snake it out so that it can keep up with the quick volume of water that this pump puts out.  No fault of the product though, this pump works perfectly and it fixed my problem.  If it lasts 6 years like the last pump did, I can't really be too mad at that.  nice part, not terribly difficult to install.  expect to pay a service company 60 to 90 minutes for installation, although if they're good they can probably do it in 30min.  It seems like more work, but take the front panel off and you'll get it done faster. it's not that bad.
