Why does my Hobart UX leave stripes and stains on dishes?
- AAmy WarnerAug 1, 2025
If your Hobart Dishwasher leaves stripes and stains, it could be due to several reasons. First, the rinse aid concentration might be too high; in this case, reduce the quantity as per the instructions. Alternatively, hard water or high mineral content could be the cause; check your water quality and consult your local water authority for details. The ideal degree of hardness is 4° Clark, and the ideal conductivity value is max. 80 µS/cm for stainless steel washware and max. 400 µS/cm for dishes. Conversely, insufficient rinse aid concentration can also cause stains, so increase the quantity according to the instructions. Finally, if your machine has a softener, ensure you are using only granular regeneration salt.
