Dishwasher runs but dishes come out dirty; food particles remain on plates and glasses.

Safety first: Turn off power before removing internal components.

• 1. Clean filters: Remove the lower rack and take out the coarse and fine filters. Rinse thoroughly and clean the sump area of debris.
• 2. Clean spray arms: Remove upper and lower spray arms. Rinse under water and use a toothpick to clear blocked jets. Ensure they spin freely when reinstalled.
• 3. Check loading: Make sure tall items do not block the rotation of spray arms and that dishes are not nested together.
• 4. Detergent and program: Use high-quality dishwasher detergent and select an appropriate cycle (e.g., Intensive) for heavily soiled loads.

If performance remains poor, the circulation pump may be weak and require replacement.
