| F36 | PCB anomaly | PCB fault (VMF7 ref. 39803410). If it persists after a reset, the manual instructs to replace the board; check supply voltages, grounds, and connectors before replacing it. |
| F10 | Microprocessor anomaly | Internal CPU error on the PCB; if the reset does not clear it, the official instruction is to check and, if necessary, replace the main board. Verify supply, neutral/ground connection, and network stability before replacement. |
| F22 | Microprocessor anomaly | Same diagnosis as F10 in the NEW ELITE series; if after disconnecting/connecting it persists, check/replace the PCB. Confirm voltages and grounds; if they are correct and the fault continues, replace the PCB. |
| F25 | Software anomaly | Software error on the PCB; the official procedure indicates to reset and, if it persists, check/replace the main board. Verify power supply and wiring; if the fault repeats, replace the PCB. |
| F8 | No flame after the ignition phase | Among the documented causes is "control board anomaly"; a defective PCB may not manage spark/ionisation or output to the gas valve. Check the electrode, grounding, and wiring; if they are correct and there is no command/output from the PCB, replace it. |
