Dishwasher displays F9; cycle may stop unexpectedly, often during drain or fill transitions.

Safety first: Turn off the circuit breaker or unplug the dishwasher before accessing the control panel.

• Power reset: Disconnect power for at least 5 minutes to allow the control to fully discharge. Restore power and attempt a new cycle.
• Inspect wiring: Remove the inner door panel to access the Fagor control board. Check all harness connectors for secure fit and signs of overheating.
• Check supply voltage: Ensure the dishwasher is connected to a stable mains supply within the specified voltage range. Avoid shared circuits with heavy loads.
• Board inspection: Look for burned components or tracks on the PCB. If visible damage is present, the board must be replaced.
• Professional service: F9 often indicates an internal PCB fault; replacement or reprogramming should be performed by an authorized Fagor service center.
