Why do white stains appear on tableware after washing with the Xiaomi Tabletop Dishwasher?

White stains on tableware after washing can be caused by several factors:
1. Using too much dishwasher powder can lead to white residue on dishes. Be sure to adjust the amount of dishwasher powder based on the number of dishes being washed to avoid buildup;
2. Softening salt helps reduce water hardness. In areas with hard water, not using softening salt regularly can lead to white stains, often caused by limescale buildup;
3. In regions with water hardness above 500ppm, installing a water softening device at the dishwasher's water inlet is recommended to prevent stains and improve washing performance.
