As noted above and some residue noted on glassware. I have run 2 cycles with white vinegar and the inside tubs are still streaky. I talked to my plumber and he suggested the aforementioned fix for my stated problems. Both dishwashers, flanking my center sink started with this problem about 6 weeks ago. I cleaned the tub with some ss cleaner when it started, and made sure my jet dry was filled and checked any other problem I could think of, but the steps haven't worked perfectly. I would say maybe the tub is marginally better, but I also haven't run a full load since I ran the vinegar twice in each washer. Any ideas to solve this problem?
