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

Safety first: Switch off power before removing internal parts.

• Clean filters: Remove and thoroughly clean all filters under hot water.
• Clean spray arms: Remove upper and lower spray arms. Rinse and clear blocked jets with a toothpick. Ensure they rotate freely when reinstalled.
• Check detergent and salt: Use quality dishwasher detergent and ensure the salt reservoir is filled if you have hard water. Adjust rinse aid as per Hoover manual.
• Check water temperature: Ensure the hot water supply (if used) is at least 50–60°C, or allow the machine to heat properly by not opening the door mid-cycle.
• Verify water level and pump: If water level is low or spray arms barely move, investigate fill issues or a weak circulation pump.
