Dishwasher shows F6E3 and may stop with water remaining in the tub or not detect correct water level.

Safety first: Disconnect power and water.

• Access sensor: Remove the lower access panel and locate the water level or flow sensor (often integrated with the sump or side wall).
• Inspect tubing: If a pressure hose is used, check for kinks, clogs, or water trapped in the hose.
• Clean sensor area: Remove any scale or debris around the sensor port that could block water or air flow.
• Check wiring: Ensure the harness to the sensor is secure and undamaged.

Repair action: Replace the flow meter or pressure sensor if cleaning and hose inspection do not resolve the F6E3 error. If the sensor tests good but the error persists, the main control board may be at fault.
