Product review (5 stars): Fixed my LG TROMM WM2277HW washer.
A few months back my LG WM2277HW washing machine stopped pumping water, rendering it useless.  After some searching on the web and checking the pump filter, I figured the next most likely culprit was the water pump and ordered this as a replacement.  Installation required a fair amount of disassembly, but I followed the directions from a video I found online and it went smoothly.  This pump is almost a perfect replacement for the existing part, I had to shave a plastic fin off of the existing housing cover with a Dremmel to get it to fit, otherwise everything lined up and popped into place.  The whole operation took about an hour to get everything disassembled, installed, and reassembled.  This new pump has been in place now for several months working perfectly.  It's reasonably priced, installed easily, and works great, what's not to love?
