Dishwasher runs but dishes come out dirty, with food residues and poor cleaning performance.

Safety first: Switch off and unplug before removing internal parts.

• Clean filters: Remove and thoroughly clean all filters under hot water.
• Clean spray arms: Remove upper and lower spray arms and clear all jets with a toothpick. Rinse well.
• Check loading: Ensure large items do not block the rotation of spray arms. Follow Bauknecht loading diagrams in the user manual.
• Use proper detergent: Use high-quality dishwasher detergent and ensure the rinse aid dispenser is filled.
• Test circulation: If cleaning is still poor, the circulation pump may be weak and require replacement.
