Dishwasher does not detect water level correctly, may overfill or stop with F06 indicated. Sometimes accompanied by continuous filling then draining.

Safety: Isolate the appliance from mains power before removing side panels.

Locate the pressure system:

• On many Indesit dishwashers, the pressure switch is mounted on the side wall or base, connected to the sump via a small rubber hose.
• Remove the left or right side panel to access it.

Clean the pressure hose and chamber:

• Carefully pull off the small rubber tube from the pressure switch and sump.
• Blow through the tube; it should be clear. Rinse it under hot water if blocked.
• Use a thin cable tie or pipe cleaner to gently clear the pressure chamber spigot on the sump (do not puncture the plastic).

Check the switch and wiring:

• Inspect the switch connector for corrosion or loose pins.
• With a multimeter, you can gently blow into the switch and listen for clicks while checking continuity across the terminals (refer to service data for correct pins).

Reassemble:

• Refit the hose securely with no kinks and ensure it has a smooth rise from sump to switch.
• Refit side panel, restore power, and run a test cycle to confirm normal filling and draining.

If F06 persists after cleaning, the pressure switch assembly is likely defective and should be replaced.
