Safety: Isolate power before accessing the electronics.

1. Power reset: Turn off power for at least 60 seconds, then restore. Sometimes transient memory errors clear with a full reset.
2. Check model configuration: If the PCB was recently replaced, ensure the correct Ferroli parameter set was programmed by the installer.
3. PCB replacement: Persistent A14 usually indicates a defective control board. Have a Ferroli-authorized technician replace and configure the PCB.
