Salt at the bottom of the dishwasher ⇐ Chrono

[Margarita]

Hello. I bought a PMM Krona Cascata 60 bi less than a month ago. It washes well, but we were faced with the fact that after each wash, salt remains after drying (from the lid of the container with salt right up to the filter), we set different hardness, the picture does not change. They wipe the bottom after each wash and every other time, the situation repeats itself. Slowly rust begins to appear. Please tell me who has encountered this problem and how did you solve it? Or is this a defect and it’s better to immediately apply for warranty?
