Dishwasher reports F10 or 10 flashes, often associated with water level detection issues such as overfilling or not detecting empty.

Safety: Unplug the appliance and turn off the water supply before removing panels.

Inspect pressure system:

• Access the pressure switch and hose as described for F06.
• Ensure the hose is not full of grease or detergent residue; clean thoroughly.
• Check that the switch clicks and changes state when gently blown into (use a multimeter to confirm contact change).

Check for overfill:

• If the tub is visibly overfilled, manually bail out water and check that the drain pump can empty the machine when a cancel/drain is selected.
• Verify that the drain hose is installed at the correct height to prevent siphoning.

Reassembly and test:

• Refit the hose and switch securely, restore power and water, and run a short cycle.

If F10 persists and the pressure system is clean, the sensor or control board input may be defective and require replacement.
