I'm starting a new thread on this machine.  I picked it up today after making an offer the seller accepted.  It has some issues and I don't know how serious they are.

First off, rust at the bottom of the sump, funky bushings under the wash arm, and a not so fine fine-mesh filter.

Underneath.  The seller said he had run the machine yesterday before removing it.  If that's true, it appears the motor has barely escaped getting fried.  I haven't attempted to test out the machine yet.

I'm wondering how rust would have accumulated around the rinse aid filler.

The seller said they have soft water.

I have my spare ISE (a series 21 or 22 clone) that works fine, but I'm not sure I want to harvest parts off of it if this Superba is too far gone or too much trouble to bring into safe and effective working order.

I appreciate any advice that can be offered regarding the issues presented in the photos above.

Upon further inspection, I noticed that the detergent dispenser is the older design with covers for both cups.  Was this type retained on only the series 21 Superbas?  Could it be an indicator of this being an early production machine from before Whirlpool made their changes to the dispenser, or is the pre-wash cover required on Superbas due to their cycling sequences?  My KDI-21 dispenser was the later type with a cover on only the main wash cup, and had been flipped around so the cups are on the top.

My sense is that this machine will take quite a bit of work to correct the rust issues and bring back to safe operation.  The seller advised they have a water softener.  Could that have been a contributing factor to all of the rust?  Even the top racks at the rear are nearly falling apart due to rust.
