This is where I stopped...
Greetings all -
This is where I stopped, I couldn't seem to get the drain pump impeller out. Even so, i'm not quote sure what I'm looking at or for.
...pretty messy, eh? There was a lot of water that I soaked up along the process. And I gave some of the parts I did remove a cleaning.
Any suggestions? If you guys think a new pump cover would do the trick i'd be happy to buy one from you guys, but honestly I don't know.
I'm very thankful for your guys time and support. Thanks much, any advice appreciated.

Someting looks fishy and probably smells as bad!
Rookie,
In the picture of the wash impeller, it looks like the keyed washer that locks the wash pump impeller to the motor shaft is missing or out of position. Don't bother with the drain impeller, If it looks good and happens to be stuck, leave it alone. If it is not leaking..all the more reason not to touch it.
If I can attach this breakdown it more clearly shows how the pieces fit together. If the washer was not there or installed wrong, the impeller would not turn very well if at all and since the drain impeller is driven by the wash impeller(they are keyed to lock together)then you will not pump all the water out.
Have you checked that bushing yet? It looks like the water was spraying out between the housing halves which may have been caused by that bushing preventing the water from going into the wash arm. There really is a lot of pressure in there. And also check and make sure nothing is up inside the top support piece.
As far as the rust stains go, pick up some Zud powder cleanser and make a paste of it and rub it into the stains and let it set for a while. It contains Oxalic acid which will take the rust stains out. Do that when you have the pump and drain working so you can fill and rinse it better.
I might as well just add the link and you can see for yourself.
Again if you want to call, let me know

Hrmm....
Ok, as for the bushing. Well, i'm not sure if it is good or bad really. If you pull the drain cover by its very higest point, i would say you could ever so slightly movie it up and down, maybe a milimeter. The brass ring aroung the white while it does move slightly doesn't really move into one position or another.
I tried holding the pump cover upside-down underneath the faucet and ran water through the holes, water was flowing through from the bottom and out the top.
When you say "it looks like the keyed washer that locks the wash pump impeller to the motor shaft is missing or out of position"... is this a problem?
Unfortunately the link you provided requires an account to access the info, so I could not see anything.

sorry you couldnt see the picture
I will fix that and send it to you. I forgot that I was signed on and it let me right in.
The keyed washer MUST be in place correctly or else the wash impeller wont be locked on to the motor shaft and then it won't lock on to the drain impeller. The shaft turns the wash impeller which in turn turns the drain impeller. The machine is draining probably only because the drain impeller is stuck to the shaft as you mentioned. I will post the breakdown here in a little while. Give you something to fiddle with today!

Sorry to keep you waiting
Here is the breakdown of the pump unit so you can see how it all fits together and how the keyed washer has to be installed.
I have seen service techs forget to place it properly and have the pump deliver next to no water at all, not to mention when they also replaced a shaft seal, the seal leaked like crazy because all the parts were not then pushed down properly to make the seal work. But don't worry in your case since you said the drain impeller is stuck! It should be fine as long as you don't damage it .
let us know how you make out.
Now lets see if I can port this diagram over to here!

keyed washer?
Thanks much. So, I have to assume the keyed washer is missing? Altho, I have no idea how. Is this a common or proprietary part? Would this part missing be the cause of the poor performance?

if it isnt there, you need one!
That part is the "KEY" to the whole thing working correctly.And YES, it is proprietary.
If you don't have it you need to get one. Hobart sells them as part number 81492 and is not very expensive.
Had I known you were possibly missing parts, I would have scanned the part numbers for you.Check what you have there to see if you have all the parts shown that are numbered from 1 thru 5. There should be 2 of part number 3 which is a spring washer. This keeps pressure on the hardware tro prevent it from coming loose. Let me know what you need and we can send it if you don't have a local office near you.
You can find one by calling 1-888-4HOBART and follow the prompts to find an office by name and they will connect you right to the nearest office. Let me know if you need more part numbers. Please dont tell them it is for a Kitchenaid machine.
Contact me FIRST for the part numbers otherwise you will get an incredible run around. Just remember. It was nearly 25 years ago that WP bought KA and not many guys at Hobart these days know that KA was part of our history!

What am I missing?
Greetings again -
OK - I may have called the part that I am possibly missing the wrong name.
I have checked parts numbered 1-5, those I have.
In the pictures posted above between "pic 2" and "pic 3", I removed the Drain Pump Cover Plate and screws (parts numbered 26 and 27) and deflector ring (part 8).
So my problem appears to be that I did not remove or find any parts that look like numbers 9, 10, 11 or 12.
So in my "pic 3" when I removed the Drain Pump Cover Plate + deflector ring, all I saw was the metal cylinder jutting out and the part hand labeled in the diagram as "this locks into wash impeller".
Does this make sense?

OK OK, forgive the newbie...
I was able to remove parts 9-10-11, they were just caked in there under the dried white stuff.
But that "part that locks into the wash impeller" does not want to come out and I don't want to break it.
So, where does that leave me now?

Like I said!
Leave it alone! If you force it, you will probably break it. It forms the the upper half of the shaft seal holding the ceramic portion and the lower seal is mounted in the bottom plastic housing which is the carbon part of it.
Try to reassemble the parts in the proper sequence and see if the top impeller locks into place. Many times the person putting it together forgets to line up the flats on the motor shaft with the flats on the keyed washer and they dont get washing action.
If you put everything back correctly and the motor runs, then you should be pumping water.

Just a suggestion....
Since you have gone this far.... Make sure the impeller is in good shape. Broken glass and bones are good for chewing those up. I would hate to see you put it all back together and find out the impeller was part of the problem.
