Bought a house in March, installed a brand new 100 Series Bosch dishwasher myself which I found on this website https://dishwashingsecrets.com/. The issue is that, despite the instructions saying to not pre-rinse the dishes, there’s almost always a couple dishes that come out dirty. Could be some sort of colored stain that wasn’t on the dish when it went in there, could be like a film/residue where you can see it at and angle and can see where the silverware scraped against the dish, could be coffee stains on the inside of a mug. We do have very hard water, so I stopped using the recommended Finish tabs and went to Cascade gel so I could use more detergent per load, but that’s still not making it so that it cleans consistently. I understand that not every dish is going to come out clean every time, but it feels like we’re getting way more that needs to be rewashed, and more frequently, than we should. Does anybody have any recommendations on how to make this clean better?
