How to Fix / Troubleshooting

Safety first: Disconnect the appliance from mains before opening any electronic control housing. Risk of electric shock.

  • Power cycle: Unplug the freezer for 10–15 minutes, then reconnect. If F01 returns immediately, the board is likely faulty.
  • Inspect control board: Access the main control module (often at the top or rear). Look for burnt components, bulging capacitors, or signs of moisture damage.
  • Check connectors: Ensure all harness connectors are fully seated and not corroded. Reseat each connector one at a time.
  • Surge protection: If the error appeared after a power surge, consider using a surge protector after repair.
  • Replace control board: If visible damage is present or the error persists, replace the main control board with the exact Hotpoint-Ariston part number for your model. Transfer any jumper settings or wiring exactly as original.
