What does error A07 mean on a Ferroli boiler?

Error A07 on a Ferroli boiler indicates high flue gas temperature - the flue gas probe has detected excessive temperature in the exhaust system. This may indicate a blocked or restricted flue, heat exchanger issues, or a faulty flue probe. Contact a Gas Safe registered engineer to inspect the flue system and heat exchanger.

What does error A05 mean on a Ferroli boiler?

Error A05 on a Ferroli boiler indicates a fan error - the fan may be damaged, out of balance, or not receiving correct power supply. Listen for unusual noises and try resetting the boiler once. If the fault returns, contact a Gas Safe registered engineer for inspection.

What does error F14 mean on a Ferroli boiler?

Error F14 on a Ferroli boiler indicates a fan problem with an incorrect tachometer signal or debris affecting operation. Contact a Gas Safe registered engineer to inspect the fan, clean any debris, and test the tachometer signal.

What does error F21 mean on a Ferroli boiler?

Error F21 on a Ferroli boiler indicates flame loss during operation or insufficient pressure. Check that the gas supply is on and the ignition electrode is clean. Ensure the system pressure is between 1.0 and 1.5 bar. If the fault persists, contact a Gas Safe registered engineer.

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.

Why do I have heating but no hot water from my Ferroli boiler?

When heating works but there is no hot water, the most likely cause is a faulty diverter valve. This component switches the boiler between heating mode and hot water mode, and if it gets stuck in the heating position, hot water will not be produced. A Gas Safe registered engineer can diagnose and repair this issue.

Does my Ferroli boiler have a holiday mode?

Many Ferroli boilers include a holiday function that can be set for periods from 1 hour to 45 days. When activated, heating and hot water production are switched off to save energy, but the frost protection function remains active to prevent freezing. The boiler automatically returns to normal operation when the set holiday period ends. Check your boiler manual for the specific menu path to access this feature.

What does modulating burner mean on my Ferroli boiler?

A modulating burner automatically adjusts its output to match the heating demand of your home. Rather than running at full power and cycling on and off, the boiler continuously varies its flame size. This provides more stable temperatures, reduces energy consumption, and extends boiler life. Ferroli condensing boilers can modulate down to as low as 10% of their maximum output.

What does it mean when my Ferroli boiler is in lockout?

A boiler lockout is a safety feature where the boiler shuts down completely due to a detected fault. Common triggers include low water pressure, ignition failure, no gas supply, overheating, or circulation problems. The display will typically show an error code indicating the cause.

What is the best temperature setting for my Ferroli boiler?

For central heating, a flow temperature of 55-65°C provides a good balance of comfort and efficiency for most homes. For hot water, 50-55°C is typically sufficient for domestic use while minimising energy consumption.
