Dishwasher runs but dishes are not getting clean; food residue remains on plates and glasses.

Safety first: Turn off power before removing spray arms if you need to use tools.

Steps:

• Clean filters: Remove and thoroughly clean the coarse and fine filters under running water. Reinstall correctly.
• Clean spray arms: Remove upper and lower spray arms. Rinse and clear blocked jets with a toothpick. Ensure they spin freely when reinstalled.
• Check loading: Avoid nesting bowls and stacking items so that water cannot reach surfaces. Keep large trays away from blocking the lower spray arm.
• Use correct detergent: Use a quality dishwasher detergent and ensure the salt and rinse aid reservoirs are filled according to water hardness.
• Run a hot cleaning cycle: Use a dishwasher cleaner on the hottest program to remove grease and limescale from internal parts.

When to call a technician: If cleaning remains poor after maintenance, the circulation pump may be weak and require professional evaluation.
