Product review (5 stars): Easy install once you figure out one thing...
This is shipped without installation directions which is as expected. You just pop the old one off through the back of the washer, and feed the new one through. Please note: ours was shipped with the hose looped through the plastic piece incorrectly. It just made it more compact for shipping. As soon as we figured it out (just pulled the old one and made sure to match the new one to it) installation was quick and easy. We didn't have to open to back of the washer; turned it on it's side and  it took about 15 minutes. DIY saves money for sure.
