In the Eye of the Beholder
Ralph, I am attaching the pictures of the machine I spoke about. It has the Stainless Steel panels and does look pretty classy!
That indicator light is the water heating light which comes on during the water heating delay. The machine heats the water to approx 140 and then starts washing. It does that in the first prewash/wash of the full cycle which is followed by a rinse and then again in the main wash of the full cycle which is also the main wash of the light china cycle. So on full cycle, you get at least a prerinse/wash followed by another rinse, then another wash and at least one rinse, though IIRC, there are 2 rinses with some purges in between before the final drain and dry. I had the more up to date version built by WP which was the Hobart design but with the element above the sump and the plastic blower housing. The machine in the ad had the older style metal housing with the enclosed element under the tank.
As far as quiet goes, yours may have been a bit quieter than this machine. I wrapped the one in the pics with another insulating cover but it is still loud compared to the new machines out there but probably quieter than the Thermador.
I also find that if you can slide some sound absorbing material under the unit it will make a difference. Dynamats come to mind and also, if you fill the inner door with unfaced fiberglass, it helps too.
The quiet scrub machines differ greatly from the whisper quiet models in that they lack the covering of almost 1/4" of that black sound deadening material which wrapped around the top, bottom and all 3 sides of the machine plus an additional sound blanket. The KDS21M I just took out of my kitchen was worlds ahead of any other KA we used in terms of noise, but still a loud machine compared to the KUDP02IRWH2 we are using today.
Since you know how your old 21 worked, I assure you that if the machine in the ad is in good working order, you will be just as satisfied with it. You would be well advised to try and find a top rack with the adjusters.It will make the machine much mor versatile, though having the Thermador with no real options for the racks,the Kitchenaid would not seem too bad as it is!
