Irreversible clouding of glassware

Irreversible clouding of glassware - Non-dishwasher-proof glasses or lengthy steam phase

Bosch · Dishwashers Series 6

What does Irreversible clouding of glassware mean?

Glasses appear permanently cloudy, indicating damage rather than residue. This can be due to using non-dishwasher-proof glassware, or exposure to a lengthy steam phase.

Common Causes

  • Glasses are not dishwasher-proof, only suitable for dishwashers.
  • Long-term wear or changes must be expected for glasses only suitable for dishwashers.
  • Lengthy steam phase (standing time after wash cycle ends).
