Dishwasher runs but dishes come out dirty or with food residues.

Safety first: Allow the machine to cool before cleaning internal parts.

• 1. Check loading pattern: Ensure large plates or trays are not blocking the rotation of spray arms or preventing water from reaching upper racks. Avoid nesting bowls.
• 2. Clean filters and spray arms: Remove and clean filters and spray arms as described above.
• 3. Use correct detergent: Use high-quality dishwasher tablets or powder suitable for Constructa dishwashers. Avoid hand dishwashing liquid.
• 4. Select appropriate program: For heavily soiled dishes, use an intensive or auto program rather than eco or quick cycles.
• 5. Check water hardness settings: Ensure the water softener is correctly set and salt is present to prevent filming and poor wash results.
