Possible Causes

Corrupted EEPROM on main PCB, Incorrect control board fitted, Power surge damage to memory, Software fault

How to Fix / Troubleshooting

Safety first: Disconnect power before handling the control board.

Step-by-step checks:

  • 1. Power cycle: Unplug for 15 minutes to allow capacitors to discharge, then reconnect. Sometimes this clears minor memory glitches.
  • 2. Check model label: Confirm the control board part number matches the refrigerator model. A wrong PCB can cause F09.
  • 3. Inspect PCB: Access the main control board and look for burnt components, bulging capacitors, or signs of moisture.

When to call a technician: F09 typically requires control board reprogramming or replacement with the correct Indesit-coded PCB. This is usually a professional job, as service tools may be needed to load the correct configuration.
