Product review (3 stars): Worked, easy install, but there is some whistling noise.
After diagnosing that the water supply switch had gone bad on my LG washer, I found this replacement one.  I watched a couple of YouTube videos to figure out how to take the top off the washer and get to the switch.  It takes about 30 minutes to install, probably faster is if your washing machine is in an area where there is some working room on the sides.  I do now here a whistling noise that I didn't hear before. I noticed that 3 other reviewers had had the same problem.  For the price, the noise isn't that bad and if it really bother you, its so easy to replace and cheap, just buy  a 2nd one and try again.  It solved the problem, LG washer is working and no more water leaks.
