Product review (5 stars): YOU CAN DO IT!!!!!!!!!!!!!!
Philips screwdriver, flat bladed screwdriver, and a little patience.  Takes about 30 minutes total to do the entire the job.  Your softener will work again and your tub will fill properly and no more washed out floors.  Take the back two screws off the top of the washer.  Next take the top of the washer off.  look to your left, yup, there it is the valve that you are going to replace.  Next  put the flat bladed screwdriver into the back of the valve area and pop the valve pins so the back plate can come out.  Remove the back plate holding the valve in.  Now remove the valve by unscrewing the two philips head screws one on each side with the philips screw driver.  wiggle the valve out.  There are two black rubber boots on the end of the valve.  They may stay in the washer or come off on the valve.  You will need these again for the new valve so keep these.  Reinstall new valve.  Walahhhhh! you are now a washer repair person and you will be done after reinstalling a few screws.  Saved your self a boat load of money!  Congrats!!!!!!!!!
