Dishwasher shows iF0 and may run the drain pump continuously.

Safety first: Disconnect power and close the water supply tap.

• Check water level: Open the door. If the tub is overfilled above the filter level, manually remove water with a cup and sponge.
• Inspect inlet valve: With water supply off, disconnect the inlet hose and check for debris. If water continues to flow into the tub when the machine is off and water supply is on, the inlet valve is stuck open and must be replaced.
• Clean pressure system: Remove and clean filters and sump. If accessible, clear the pressure hose from the sump to the pressure sensor.

If iF0 persists, the pressure sensor or inlet valve is likely faulty. Due to flood risk, have a technician perform further diagnostics and replacement.
