Dishes not cleaning properly; items come out with food residue, film, or grease despite completing the cycle.

Safety first: Turn off power and allow the machine to cool before removing wash arms or filters.

• Clean filters and sump: Remove all internal filters and strainers. Rinse under hot water and scrub off grease and debris. Clean the sump area of any buildup.
• Clean wash arms: Remove upper and lower wash arms. Use a brush or toothpick to clear each nozzle. Ensure arms rotate freely when reinstalled.
• Verify wash temperature: Check the displayed tank temperature during operation. If below Meiko’s recommended range, investigate heater and thermostat issues.
• Check detergent dosing: Confirm that the detergent container is not empty and that the dosing pump is primed and operating. Adjust dosing settings according to water hardness and soil level.
• Assess wash pump performance: Listen for weak or irregular pump noise. If circulation appears poor even after cleaning, the wash pump or impeller may be worn and require replacement.
