Product review (5 stars): Works like a charm
Likely not OEM as it didn't have the LG logo on the box, however, the pump looked identical and fit perfectly. No issues what so ever as of yet. I'll add an update to the review in a few months, as it seems like most of the negatives say this pump starts having issues after about two months.

If you find my review helpful, please mark it as such. Thanks!
