Product review (5 stars): Fits my  Whirlpool duet 9600
This little drain pump fits my Whirlpool  Duet WFW 9600TW01.
 Remember to un plug washer before you start.
 I put a cookie sheet under the washer when I started this project to help catch some of the water that will come out but you will still need extra towels to catchwhats in the lines and filter . I also dipped all I could out of the washer itself because it was at least a bucket full in there.
 It is only just a little louder than the oem when it  perfectly worked. It really gets the water out of the washer. Clothes are much dryer as  they come out too.  Like others posting, my old pump had starting leaving the clothes very damp and then would make grinding noises as it tried to drain the water. Also had the suds code.
 My oem pump was mounted to the plastic filter housing with only 3 phillips screws. There are more vacant holes that could be used - I am guessing in case some are ever stripped another can be chosen?  there are also several  protrusions that help line up the pump onto the drain filter casing. I put just a little petroleum jelly on the included O ring to hold it in place and tightened the screws up lightly and then come back to snug  them down firmly  after all were seated.( Like one would do on a car tire.)
When removing the drain part where this new pump attaches, if you use large vice grips, it  will make the hose clamps much easier to get off since they hold in place.  There are some good u tubes for removing the entire assembly  but on mine, after I got the hoses pushed off of it, I just pulled down on the orange tab at the base of the front and then looked to the back and wiggled the 2 rear "feet" out of the retaining holes. Works wonderfully.  edit: the tan colored pump in the picture is the new one.
