Not to Hi Jack...
@ mark wp...
I have never grown to like the granite deal. I like Corian or what you've got.
I just can't get used to Granite. For some reason, I can't tell if it's clean at a glance. I have to look at different angles with the light reflecting to see where the soil is.
Any way, I like your counters. They're "Handsome".

Let's do this
Since there are no corners in the upper rack, let's up the ante, shall we?
Finish Quantum in the pre-wash cup, and liquid chlorinated gel in the covered cup, to get rid of errant coffee and tea stains.
Stay tuned...[this post was last edited: 1/11/2016-19:31]

For Greg
This challenge is sponsored by all-new Cold Water Cascade. For virtually clean dishes!
Strange; it was funnier ten years ago...

My arms ... dishwasher spray arms, that is ... have a slightly-elongated nozzle on the surface at one end and a longer slit cut to the edge on the other end which just barely reaches to the glass at the corner, which is why a smaller diameter glass at that position wouldn't fully catch the spray.
I'm repeating the test under different parameters. Results tomorrow.
The results...
So, the cycle came to its end, which caused my ears to perk up when I heard the scavenge-drain, and not a subsequent fill. Off to see what happened...
(NO, GREG, WE WILL NOT BE RUNNING IT THROUGH THE HEATED DRY.) ;-)

Open, sesame...
Oooh! Steamy. We have our hot water at about 145, so the dishwasher gets nice, piping-hot water. Good thing, since this one lacks a supplemental heat cycle.
Please ignore obligatory crap piled on dishwasher. God help us if we had a Mobile Maid.

Top rack
Not bad. A trace of crud where the glass bows inward for the ring near the base. Otherwise, mostly clean.
Remember, this is 40 minutes later, not 3.5 hours.

Bottom rack
Exactly as I expected--completely untouched. But I'm not surprised--I had no expectation that the lower arm was designed to reach the corners quite that way.
I had to go back and wipe peanut butter off the tines. Ew.

Hypothesis
Here's what I suspect about the results.
First, as an aside, I'd love for the Quantum pack to fit in the main wash cup, but I'd also like a pony. Truthfully, the first wash/main wash segments on this machine are pretty identical, so it's kind of a six-to-one, half-dozen-to-the-other issue. It's not like a GE, where missing the main wash is a big deal due to its duration. Still, chlorinated gel is not a great peanut-butter fighter.
This test revealed something I secretly wondered about all along. The Roto-Rack was designed to eliminate dead spots in the top rack, and in that respect, it performs admirably. However, the jets are pretty aggressive on this unit (as in, canted at sharp angles). Washing performance isn't just about reaching the dishes with water--it's at least partially a factor of how much time the spray spends on the surface of the dishes. If you pass the wash arm too quickly over them--or spin the rack too quickly above--the water spends a very limited duration washing the dish, and the "scrubbing" effect achieved by a little bit of dwell is negated.
So why don't the Big Blue KitchenAids suffer this injustice, you ask? I suspect it has a lot to do with well-engineered pressure of the spray from the arm, and the sheer volume of water those machines could move. When I videorecorded one in slow-motion on my iPhone, the water sent upward from the arm was still falling back toward the sump as the next sweep of the arm went by. That's some serious water movement. The Roto-Rack won't come close.
Still, for daily dishes, we've gotten great results from the combination above--no rejects so far.
I guess we'll have to limit our imbibition of peanut butter, though.

I'm not surprised by the fine results from the Roto Rack. We had a 1973 (or early '74) Lady Kenmore. For kicks, I'd angle the dishes for maximum rack rotation speed. That thing would spin amazingly fast. Wow, a 40-minute cycle. That's about half the GE's main wash time and about one-third of the final rinse, LOL.
mark_wpduet,
It is out in the garage. I swapped it out for a damaged G6365 Miele I had at the store.
I thought about selling it but am now waiting for a black control panel and front panel assembly with handle to come in. I'm going to swap out my mom's old short tub whirlpool that is louder than a diesel truck.

Aha!
Failure, that's for what we're looking!
Smaller juice glass that fits on the side shelf. The 11" x 14" Pyrex baking dish blocks the spray except what gets through the back corner.
Heavy cycle, which is 132 mins total (incl 28 mins dry time). Main wash 150°F / 65.5°C, final rinse 163°F / 72.7°C. Seven water changes.
The glass bowl on the shelf is moved in the after-picture. It's a little too tall to be sure the lid seals when sitting atop the plastic pitcher. The white Grab-It bowl swapped to that position had similar residue, it emerged fully clean. There's a space between the Pyrex and pitcher through which the arm can directly spray.

Another Contender from the Drawer Department!
Here we go again!
This load probably qualifies for a BobLoad, too - having sat for three days (the PB glass was already dirty, and I smeared it with my FINGERS this time. Oh the guilty pleasure of it), and being stuffed to the gills.
The glass in this corner was blocked by cereal/soup bowls, cups/mugs underneath and of course hindered by a less-than-perfect "Phosphate Free" dishwasher powder being used in semi-hard water (Softener restored to service temporarily).
Apologies for the poor quality, was using my iPhone 3GS camera once again.
The initial photos show some development of the load before I started the machine, then the final results. A little bit of mucky water collected in the plastics, but this is expected without a constant-rinsing device of some sort.
Tap was run HOT this time to full hot, 55*C.
HEAVY cycle used: 70*C (158*F) Main Wash, Final Rinse at 65*C (150*F), 4 water changes total.

It's great that John's peanut butter test has not only been done across the US, but around the world!

Nope, just changing it to black since mom has black appliances.
It is working perfectly fine, even after the potatoes.

Washer111, I'd say that's a DD BobLoad.
