Possible Causes

Corrupted configuration data in main PCB, Power surge or brownout, Incorrect replacement control board not programmed for model, Loose memory IC on PCB

How to Fix / Troubleshooting

Safety first: Unplug the appliance before opening any covers.

Initial reset:

  • Disconnect power for 15–20 minutes to allow the control to fully reset.
  • Reconnect and observe if F09 reappears.

Board inspection:

  • Access the main control board at the rear lower section.
  • Check for signs of overheating or physical damage around any memory ICs or microcontroller.

Corrective actions:

  • If the board was recently replaced, verify that the correct Indesit part number was installed for your exact model and that any required configuration jumpers or programming steps were followed.
  • If F09 persists and wiring/sensors are confirmed good, the main PCB likely needs replacement with a properly configured board.

Note: EEPROM reprogramming typically requires manufacturer tools; in most domestic situations, the entire board is replaced.
