The impeller kit I have is 4386996
I checked for a factory instruction sheet and there was not one to be found, sorry.
I thought that I would be able to only pull out the pump from underneath without removing the dishwasher from the counter and replace the seal.
Yeah, this one your going to have to remove the dishwasher to work on it.
Shut the water off and disconnect the water, power and the drain hose.
Then open the door and look up under the cabinet. You should see the two screws that hold the dishwasher in place.
Remove them two screws and pull the dishwasher out.
Print the diagram out so you can look at it once you start taking thing apart.
Once you get the dishwasher out and the pump/motor assembly out were you can work on it I think you will see it's not all that hard.
Let me know if you have any more questions as you go and if you have a digital camera feel free to post photo of what your working on.
