How to Fix / Troubleshooting
Safety first: Unplug the freezer before handling sensors or the control board.
- Verify sensors: If any sensors were recently replaced, confirm they are the correct Ariston part numbers and properly installed.
- Check connectors: Inspect all sensor connectors at the PCB for bent pins or loose fit. Reseat each one.
- Power reset: After checking connections, perform a full power reset and monitor operation.
When to call a technician: Persistent F6 usually requires service diagnostics to compare sensor readings and possibly replace or reprogram the control board.
