Ferroli error codes and what they mean · Ethiopia
All 3 Ferroli fault codes in one table: what each one means, how serious it is and when to call a pro.
| Code | Appliance | What it means |
|---|---|---|
| A01 | gas boiler | The boiler failed to ignite (no flame was detected) and has locked out. |
| A03 | gas boiler | The boiler overheated and the safety thermostat cut it out, usually because heat is not being carried away from the boiler, for example by closed radiator valves or poor circulation. |
| F37 | gas boiler | The heating system water pressure is too low, usually because of a slow leak or water lost from the circuit. |
