Dishwasher runs but dishes come out dirty, with food residues and film on glasses.

Safety first: Turn off the dishwasher before cleaning internal parts.

• Clean filters: Remove and thoroughly clean the coarse and fine filters under warm water.
• Clean spray arms: Remove upper and lower spray arms, clear blocked jets with a toothpick, and rinse.
• Check loading: Ensure large plates or trays are not blocking the spray arms. Do not nest bowls; leave gaps for water flow.
• Use proper detergent: Use high-quality dishwasher tablets or powder and adjust dosage according to water hardness. Always use rinse aid unless using an all-in-one product approved by V-ZUG.
• Run a hot intensive cycle: Periodically run a hot program with a dishwasher cleaner to remove grease and limescale.
