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

Safety first: Turn off power before removing internal components.

• Clean spray arms: Remove upper and lower spray arms. Rinse under hot water and use a toothpick to clear blocked jets.
• Clean filters and sump: Remove and wash the filters. Check the sump for debris that could restrict flow.
• Check water level: Start a cycle and, after filling, open the door briefly. Water should cover the filter area. If low, inspect inlet filters and water supply.
• Use correct detergent: Use high-quality dishwasher detergent and ensure rinse aid is filled.
• Avoid overloading: Load dishes so that spray arms can rotate freely and water can reach all surfaces.
