Why do white stains remain milky on utensils/glasses after washing in my NEFF S51E50X1GB Dishwasher?

  Marcia WalkerSep 8, 2025
  If you're using phosphate-free detergents with hard tap water, white deposits may form more easily on utensils and container walls in your NEFF Dishwasher. Other potential causes include using too little or unsuitable detergent, selecting a program that's too weak, insufficient or no rinse aid or special salt, incorrect water softening system settings, or a salt dispenser lock that isn't fastened.

  Food residue on utensils after a wash cycle in your NEFF Dishwasher can occur for several reasons, including: utensils placed too closely together or the utensil basket being overfilled, too little detergent, a rinse program that is too weak, obstructed spray arm rotation, blocked spray arm nozzles, blocked or incorrectly inserted filters, a blocked waste water pump, or the top basket not set to the same height on both sides. Check these possible causes.
