I don't think any dishwasher, even a PowerClean or a Hobart KA, can handle baking dishes with food severely scorched on. I normally never put anything into a dishwasher except eat-ware (plates, bowls, cups, silverware, etc.) just because of how much space large bowls and pans take up. The things put in it are nasty, but none of it is baked on of course, just dried. Anything baked/seared on gets a sprinkle of Cascade powder and soaks for a few hours with hot water, and even then it takes some effort to scrub off. With the water in a dishwasher not actually sitting still on the soil enough to soak in, and with a machine averaging an hour or two, there's just not enough time for the heat and detergent to get deep enough to dissolve it.
The previous gen WP's are insanely easy to work on, and because no one wants to let go of their PowerClean's and even Point Voyager's, parts are still readily available. I'd also have to kick a dishwasher to the curb if I had to clean out cakes of residue from the bottom like that Bosch pictured above. The WP/KM would have pulverized it and sent it on its way, as a dishwasher should.
