Dishwasher overfills slightly; water can be seen at the bottom of the door seal and sometimes drips out, but no code.

Safety first: Disconnect power and close the water tap before accessing internal level components.

• 1. Clean filters and sump: Ensure the sump and filters are clean so water can drain freely between phases.
• 2. Pressure system cleaning: Access the side or base to locate the pressure chamber and hose. Remove and flush them with hot water to clear grease and residue.
• 3. Check inlet valve behavior: During fill, listen for the valve clicking off promptly when the correct level is reached. If it dribbles on, the valve may be sticking.
• 4. Replace suspect parts: If cleaning does not help, replace the pressure switch or inlet valve as appropriate.
• 5. Technician help: If overfill persists, the control board may require calibration or replacement.
