Product review (5 stars): Very easy
Washer was stopping, half full of water.

If the clothes are still wet when it's done, try the actuator; we had to replace that a few weeks ago.  Five year old machine, average about two loads a day, very glad we didn't decide to call in a professional.  At $75/trip, both repairs combined haven't gotten as expensive as one"show up" fee!

When you've got the washer unhooked and flipped forward (put the end of the hose lower than the place the hose in back connects-- a baking pan can do the last gallon or so, but ours had about 12 gallons in it so start with a bucket) it's that thing on the left without a finger guard on it, three bolts, easy.  I would suggest that you unscrew it, then unplug it, and then fight with the hose; when installing the new one, put the hose on first.  Cut 30 minutes off of our install time when we did it that way.

If you're not sure that the pump is dead, see if you got lucky and there's a giant clog in the hole left when you pull the pump off. Can even rinse it out.

We used the clean-the-machine cycle after installing the new pump, for the test run; worked perfectly.
