A:Answer No, that's a rapidly disappearing dishwasher feature, I'm afraid. Bosch will tell you that their triple filtration is better, BUT: Now you've got a messy, nasty filter to clean. Oh, and if you forget to check and clean it after washing several loads of dishes? Well, you'll be running them through a second cycle after they all come out dirty and you figure out that the filter was clogged. No, thanks. I am far too busy to make sure that everyone in this busy household remembers to clean it. In fact, it was always on ME to remember and clean it. For what it's worth.
