GEs and detritus
The machines with the back-wall filters are phenomenal performers. Alas, this isn't one of them.
They're okay once you master loading the top rack. With most of these, I gave up trying to wash tall tumblers above, because they'd end up with debris spritzed into the glass, and never subsequently removed.
The Power Shower really helps. Rinse aid, if an option, helps even more. It seems that the sheeting, surface-tension-breaking action of rinse aid really helps shoo particles off of items to which they'd otherwise tenaciously cling.
They are good pot/pan/bakeware scrubbers, no doubt. But if you throw a lot of garbage in the machine, there will be some hanging out. Sometimes you get lucky, and it's just plastered on the tank. Sometimes, not so lucky. I avoid this by scraping off excess food soil, and making sure that tiny things like breadcrumbs get mostly dusted off first.
Machines like the 1200/2800 series and their kin (or any in the filtered category) are in a class apart, but for these filterless models, I thought the water consumption was disproportionate to the performance. For all that drama, you should get something better than "just okay" at the end of the cycle.
Filteress machines are just serial diluters, and I would readily take on a wager with anyone who'd like to run a rice-dish casserole through one of these, and commit to the heated dry. ;-)
