PowerDisk? As long as you load salt and rinse aid, it works like a charm. As you said, if you want to save a bit of money, you can 3D print a replacement. But they last long enough that I don’t mind the cost.
What do salt and rinse aid have to do with it? Those have been things you load into a reservoir when prompted for years. And for those of us who live in HN’s homeland where the water is very soft, you may get better results by not loading rinse aid (there’s some moderately compelling evidence that rinse aid is rather toxic to digestive tracts, and it doesn’t even have much rinsing benefit if you’re rinsing with soft-enough and low-enough-TDS water), and the salt is also unnecessary with soft water. You do need to poke at the dishwasher settings to make it happy without rinse aid and salt, but this is well documented in the manual.
