What does error A04 mean on a Ferroli boiler?

Error A04 on a Ferroli boiler indicates a flue gas fault, typically triggered when fault F07 has occurred three times. Visually inspect the external flue terminal for blockages such as debris or bird nests. Contact a Gas Safe registered engineer to inspect the flue system and sensors.

What does error A12 mean on a Ferroli boiler?

Error A12 on a Ferroli boiler indicates a domestic hot water sensor error causing a permanent lockout - the DHW sensor is damaged or its wiring is shorted or disconnected. Contact a Gas Safe registered engineer for sensor testing and replacement.

What does error F08 mean on a Ferroli boiler?

Error F08 on a Ferroli boiler indicates the over-temperature protection has activated due to excessive temperatures or circulation issues. Check the system pressure is between 1.0 and 1.5 bar, bleed radiators, and ensure the pump is running. If the fault persists, contact a Gas Safe registered engineer.

What does error F07 mean on a Ferroli boiler?

Error F07 on a Ferroli boiler indicates high flue gas temperature or an air pressure switch error with fan contacts. Ensure the flue is not blocked externally and contact a Gas Safe registered engineer to check the heat exchanger and flue gas temperatures.

What does error A01 mean on a Ferroli boiler?

Error A01 on a Ferroli boiler means no burner ignition - the boiler fails to ignite because no flame signal is being received. Check your gas supply is on, verify the boiler has power, and try resetting by pressing the reset button for 5-10 seconds. If the error persists, contact a Gas Safe registered engineer as the electrodes, gas valve, or PCB may need inspection.

When should I call a Gas Safe engineer for my Ferroli boiler?

Contact a Gas Safe registered engineer if you smell gas, the boiler is leaking water, you hear persistent banging or whistling noises, the same error code keeps appearing after reset, there is no heat or hot water despite troubleshooting, or the pilot light keeps going out.

Why is my Ferroli boiler leaking water?

When you see water coming from the bottom of your boiler, the most common cause is a broken internal component, typically a pump seal or pressure relief valve. This requires professional diagnosis and repair by a Gas Safe registered engineer.

Does my Ferroli boiler have frost protection?

Ferroli boilers include a built-in antifreeze system that activates automatically when the system water temperature falls below approximately 6°C. The boiler will fire briefly to prevent freezing of internal components. This protection only works while the boiler has electricity and gas supply. For extended winter absences, consider draining the system or adding approved heating system antifreeze.

How long does a Ferroli boiler last?

A well-maintained Ferroli boiler can provide reliable heating for 10 to 15 years. Regular annual servicing is essential to achieve this lifespan.

How do I repressurise my Ferroli boiler?

To repressurise your Ferroli boiler, first switch off the boiler and allow it to cool for an hour or two. Locate the filling loop (usually a silver braided hose beneath the boiler), open the valves slowly while watching the pressure gauge, and stop when the reading reaches 1.0-1.5 bar. Close the valves and restart the boiler.
