Product review (5 stars): Easy install, solve leaking LG washer
Water was puddling under the washer.  LG model WM2701HV about 7 yrs old.  Took top of washer off (undue the lower screw on the two brackets on each side in back of washer, and slide the top back about an inch, then lift off).  Noticed the original valve was all corroded and leaking.  Ordered this off Amazon, and in 2 days was back in business.  Turn off water at the wall and unscrew the exterior washer hose.  Unplug the three harnesses.  Use pliers to squeeze each of the three hose clamps and slide them up hoses an inch or two.  Twist off the three hoses, and ensure to put them on the same port on the new valve (remove from old, and replace on the new one at a time, or at least mark them before removal, so you don't put wrong hose on wrong port).  Unscrew the two screws holding the old valve in place on the back of the washer, and remove old one.  Install new one.  replace hose clamps and three harnesses.  Check for leaks.  Took me longer to type this than to replace the valve.  Although my hot water one was good still, I replaced it too.
