Product review (5 stars): Works great, quieter than my original factory valve
Very easy to install on my WM2688HWM machine.  Two screws need to be removed from the back of the unit, near the top, the top cover slides back a bit (with some force), and then lifts up.  The part has been in operation now for about a month, working great.  I also replaced my hot water valve as well, as preventive care.
