It's a fun machine. The build quality is right in line with D&M; potato chip-thin porcelain, and racks that need constant dabbing with vinyl patch. But then again, you're not far off with a Plastisol GE, depending on how it was cared for.
Mechanically, it's like a horizontal-pump, no-filter, shaded-pole motor GE, but instead of a stationary tower, it has one fixed to the rack, and the lower wash-arm jumps up and "locks" into the tower under pressure, rotating the whole affair in a plastic sleeve so that any dishes leaning near or on it can't stop the rotation of the tower within. Like a GE, one of the afflictions it can have is a leaky rubber grommet on the drain solenoid, which mine did until it spontaneously decided to stop leaking.
The drain solenoid snaps and works just like a GE. The pump is surprisingly forceful. Woe be the person who uses the portable version and forgets to put a coffee mug under the drain outlet, unless you enjoy fun new ways to do dishes and wash your countertops and floors all at the same time.
The holes on the wash-arm (which itself is very GE-shaped--a fat oval) are shaped like a Whirlpool's or a KitchenAid's, where it's a convex bulge with a goat's-eye slot in it. It does not have wide-open big holes like a GE.
The sump is in the back, rather than off to the side. It runs the heating element during the wash like a GE.
It does something like 7 water changes on the Normal cycle, so very little escapes it. Even so, the cycle's only about 55 minutes. (Pots and Pans only goes up from there.) Its most unusual feature is an Econo Wash mode that does one super-long main wash, with no water change in between, but the option to dispense detergent twice during that phase of the cycle (sounds like a poor idea, but interesting nonetheless).
Some of these had the infamous "run through the dry cycle" pumps (purportedly to enhance drying by moving an infinitesimal amount of air via the pump), with a small plastic duct to the front of the machine; if this has that, you'll notice vent slots on the black area under the kick panel. Mine doesn't do that, thankfully. The D&M Frigidaire impeller machine drove me nuts with its roaring impeller-assisted dry.
This is the only tower machine I've used that can clean tall items in the corner of the top rack--which sometimes the Bosch Thermador doesn't even do all that well (and it has double wash-arms and a constant rinse!). Still, it will likely collapse into rust someday

. I'll be ready with the plumber's epoxy and JB Weld when it does.
Given the choice, I prefer this machine; the racks are deep and flexible, and I can load fry-pans and mixing bowls all over, top or bottom. The "plates-only zone" to the right of the basket took getting used to, but it becomes intuitive after a while.
I'll do a full post on this in a few days--I actually have some "machines of ill repute" that we played with and tested thoroughly that I'm compiling a report on (including the much-adored plastic-tub D&M with soil-separator!).
