Product review (5 stars): Once i searched YouTube and figured out where the white wires were to go it worked like a charm
My issue was getting cold water at all temperature settings but no hot.  I had a little difficulty with the wiring since it did not match the old valve.  Once i searched YouTube and figured out where the white wires were to go it worked like a charm. Took a little trial and error. Make sure both white wires are on same side for the solenoid connections (one white wire on each of the 2 solenoid connections). If the water doesn't work switch both white wires to the other side of the switch.  Then it should work.  Blue wire to the cold valve, red or purple is for the hot water valve.

 I suggest using a bucket in your washer tub to catch the water during testing so you don't leave iwater in the drum. Once you confirm the valve is working you can put the washer top back together again.

For my Maytag washer the top was held by 2 springs at the front of the washer machine.  Just need to use a putty knife to get the springs to pop and the top to open.
