White chalky marks on dark dishes are a common sign that something in the wash process is not working as it should. Most of the time the cause is either hard water or a rinse stage that is not doing its job fully.
Minerals in water can stay on plates after drying and form a visible film. This becomes more noticeable on black or glass surfaces. If rinse aid is low, empty, or not dispensing correctly, water does not slide off dishes properly, leaving spots and streaks behind.
Another factor is circulation inside the machine. When spray arms are partially blocked or water pressure is weak, detergent and rinse water do not reach every surface evenly. Some dishes come out clean while others stay covered with residue.
In some cases, the issue comes from detergent not matching water conditions or from a heating cycle that does not dry dishes properly.
If cleaning the filters, checking rinse aid, and using different detergent does not change the result, the dishwasher may need technical inspection.
