What is the Ferroli Boiler FH Error?

If your Ferroli boiler displays the FH code, it’s not an error but a status code. The boiler’s water pressure should be around 1.5 bar. When the pressure drops below 1 bar and you refill the system, the FH code will appear on the display for about 120 seconds. This is not an error; it simply indicates that the boiler is in automatic air venting mode. Wait for 120 seconds without pressing any buttons, and the FH code will disappear on its own.

Ferroli Boiler FH Error Explained

The FH code on your Ferroli boiler is a temporary status message that appears after you’ve refilled the water pressure. The boiler enters an air venting mode to ensure the system is functioning properly. No further action is required other than waiting for 120 seconds.

What is the Ferroli Boiler F37 Error?

If your Ferroli boiler shows an F37 error, it means the water pressure is too low. Check the water pressure gauge to ensure it’s between 1 and 2 bar, with the recommended level being 1.5 bar. If the pressure is below 1 bar, increase it to 1.5 bar. Once the pressure is adjusted, the FH code might appear, which will go away after 120 seconds as the boiler vents the air and returns to normal operation.

Ferroli Boiler A01 Error – What Does It Mean?

The A01 error code on your Ferroli boiler indicates that there is no gas supply. If the gas valves are closed, open them. If there’s a gas outage, wait until the supply is restored. Once the gas is back on, reset your boiler to clear the error and resume normal operation.

How to Reset a Ferroli Boiler

If your boiler is showing an error that starts with “A”, such as A01, you can try resetting the boiler. Hold the RESET button for 1 second to initiate the reset. If the error persists after the reset, you should contact an authorized service provider for further assistance.
