Product review (5 stars): Right part for LG Tromm WM2277HW
I bought this to replace the drain pump on my LG Tromm WM2277HW.  It worked perfectly.  Two pieces of advice, 1.) don't disassemble the whole unit like some youtube videos show, just tilt the machine on its side and 2.) the train pump and the recirculating pump are similar enough that you can put this in the wrong place if you aren't careful or aren't paying attention.  I did it, but then swapped them back and put this in the right place and it worked fine.
