Removable streaks on glassware

Removable streaks on glasses, metallic appearance on silverware — Cleaning issues

Bosch · Dishwashers

What does Removable streaks on glassware mean?

Visible streaks on glasses or a metallic film on glassware and silverware that can be wiped off indicates an issue with detergent rinsing or wash cycle selection.

Common Causes

  • Items of dishware are blocking the dispenser lid, preventing proper detergent release.
  • Dishware has been precleaned too intensively, causing sensors to select a lighter cycle unable to remove stubborn remnants.
