Dishes are not coming out clean; food residues remain on plates and glasses.

Safety first: Switch off power before removing spray arms if accessing from below.

• Clean filters: Remove and thoroughly clean the filters under hot water.
• Clean spray arms: Remove upper and lower spray arms. Use a toothpick to clear blocked jets and rinse well.
• Check water temperature: Ensure the hot water supply is at least 50–60°C if the dishwasher uses hot feed, or confirm that the heater is working.
• Load correctly: Avoid nesting dishes and blocking the spray arms. Follow the loading diagrams in the user manual.
• Use quality detergent and rinse aid: Use branded dishwasher tablets and keep the rinse aid dispenser filled.

If performance remains poor, the circulation pump or heater may be underperforming and require further diagnosis.
