Ferroli Boiler Fault Codes and Errors

Ferroli is an Italian boiler manufacturer that currently operates in over 14 countries in Europe and Asia. Since its establishment in 1955, Ferroli boilers have been known for their cutting edge designs and aesthetic looks. However, perhaps in its pursuit for breath-taking looks, the manufacturer neglected the efficiency and reliability of its products if customer reviews are anything to go by.

Given such a bad history and the fact that you are currently reading this page, it is easy to conclude that your Ferroli boiler is having some issues. And naturally, you would be trying to crack the fault code displayed on your boiler’s display panel.

But before we get into decoding Ferroli boiler faults and errors, it is essential to state that a simple reset can fix some of the errors displayed on your boiler. However, if a reset doesn’t work, the next thing to do would be to call a certified heating engineer to take a look at your boiler.

How to reset a Ferroli Boiler

Resetting a Ferroli boiler isn’t much of a hassle. All you have to do is locate the reset button normally located at the front of the boiler and hold it down for about 10 seconds. If the reset is successful, the flame will ignite, and the error code will disappear.

One thing to keep in mind though, is that you shouldn’t press the reset button intermittently or repeatedly. This is because repeated pressing can jam your rest button and result in other issues that may require the attention of a boiler engineer.

That said, here are some of the most common Ferroli boiler fault codes.

Most common Ferroli boiler fault codes and how to fix them

• FH Error Code: This usually is due to a faulty flame detection electrode or PCB unit. Whichever the case, this is a problem you can’t fix on your own, and you need to call in a boiler engineer.
• AO1 Error Code: This is usually attributed to an ignition error due to a faulty flame detection electrode, a power fault, excess condensation, or an issue with gas supply. Luckily, resolving this issue usually is easy, and all you have to do is check your gas and power supply, then reset the boiler. However, if the problem persists, you need to contact a certified heating engineer to look at your boiler.
• D1 Error Code: This error code means there is an issue with your boiler’s diverter valve. A heating engineer can fix the problem.
• T5 Error Code: This implies a non-serious issue with the boiler PCB. To fix it, press the reset button until T5 appears on the display panel. Then, continue holding the reset button until P01 appears on the screen. Once done, set the heating temperature, and hopefully, your boiler should be up and running.
• A51 Error Code: Usually due to poor combustion. You need to call a heating engineer as you can’t handle this issue on your own.
