Chet is this your current machine ? I just bought this exact model a couple of weeks ago. It's from 1998 or that's when it was built, August 1998. I need to get the tub out of it and get a replacement spin basket. Cosmetically the machine looks pretty good and cleaned up nice. I think this has the dual action Plus agitator in it also.
Edit: I should have looked closer but mine does not have the ultra rinse. Wish it did. The Kenmore 90 serious I purchased back in March of 2003 had that. Was a great machine and I got rid of it because the stupid plug broke off it and got that junk Maytag Bravos X.
I wish it was my current machine. I am still using my Speed Queen but I changed the water valves a few weeks ago. What a difference! May I advise you doing the same? 358277 is the magic number.

Do you have control panel pics of the Kenmore you just purchased?
Take a pic of the tech sheet on your machine when its open and I'll tell you whats what.
Some Kenmores had had a spray rinse sequence in the first spin of the ultra clean cycle, others didn't. On the other hand, some machines did a spray rinse in the first spin of the permanent press cycle as a cool down, others did a half a tub drain and re-fill for a cool down. IIRC Permanent Press I and Permanent Press II respectively.
