Product review (5 stars): Abra Cadabra
I bought this because my LG WM2455HG washing machine had begun leaking.  I unplugged the washing machine and pulled it from the wall to take a look at it and it showed traces of water around the bottom of the back panel.  After taking it off and tracing the water to the top of the washer, I had to remove the top.  Once that was off I could see water on top of the hot water inlet valve.  I turned off the hot water and drained the hose and removed the valve.  I cleaned the screen and put it back on, but it still leaked when I turned the water back on.  I orderd this replacement valve from Amazon, installed it on an 'presto', it worked like magic.  No more leaks.
