Product review (4 stars): Second replacement pump better than first, for my WM3455HS washer/dryer
This part is the weakest link in my washer/dryer combo. The original pump was rattly and failed after four years, and the first replacement (ordered on this very page) lasted only about a year, making an absolutely crazy ruckus.

This time, I got luckier. For less than twenty- four bucks, I got the quietest pump of all three. I can actually watch TV now with the machine going in the open kitchen! I am not 100% sure whether I got an original part, as it doesn't say "LG" anywhere but the package, but so far I'm happy.

As for installation, I found a quick method for my particular unit - now tested twice! I flipped the washer upside down, unscrewed the white plastic bottom (worth breaking out the drill with screwdriver bit for that), and pried it open. There was an electrical box with a lot of wires attached to the bottom, which I didn't bother disconnecting. The pump, then, was hard to miss, and the three screws and two wires made for a swift replacement of the unit. Putting the plastic bottom back on, I had to make sure the two rods on it lined up with the tubes on the drum (it's a stabilization system of sorts). I'm probably describing this in a more complicated manner than it is, it's all quite intuitive if you're just a little bit handy.
