    What are boiler fault codes?

    Boiler fault codes are alphanumeric or numeric indicators generated by a boiler’s control system to communicate specific issues or malfunctions within the heating system. These codes help both homeowners and service professionals identify and diagnose problems quickly, allowing for efficient troubleshooting and repair.

    Ferroli Boiler Error codes

    Ferroli boilers are known for their excellent design which is aesthetically pleasing. However, boilers of top quality do something tend to have certain issues. On this page you will find the error codes or faults of Ferroli boilers and what they indicate, in addition to possible ways to fix these issues.

    Dante Ferroli first established the company in 1955. The original head office is situated in San Bonifacio, close to the Italian city of Verona. Ferroli has a network of branches which operates in over 14 countries across Asia and Europe. That is why they are a well-known manufacturer in the heating industry.

    Their main aim, for over 60, has been to lead an innovative approach in the heating industry and to manufacture appliances which are highly efficient, well-built and suitable to a wide range of specifications.

    Ferroli takes great pride in their ability to provide fantastic service to its customers. In 2017, the Ferroli BlueHelix Tech 25C was voted to be the best boiler and as well as the Best Purchase in the Italian magazine of AltroConsumo.

    However, in some cases, getting a new boiler might be more cost-effective than getting your old boiler fixed. Some issues might be costly to fix. What is more, a new boiler will probably be more efficient and can help you save both money and energy. That is why getting a new boiler is a good investment in the long run.

    How to reset a Ferroli Boiler?

    Resetting a Ferroli boiler is a common procedure to address certain issues or errors. Here are general steps to reset a Ferroli boiler:

    1. Locate the Reset Button:
      • Find the reset button on your Ferroli boiler. This button is often on the control panel or near the display.
    2. Turn Off the Boiler:
      • Switch off the boiler using the main power switch or by turning off the electricity supply to the unit.
    3. Wait for a Few Seconds:
      • Allow the boiler to remain off for about 10-15 seconds. This brief pause helps reset the internal electronics.
    4. Press and Hold the Reset Button:
      • Press and hold the reset button. While holding it down, turn the boiler back on.
    5. Continue Holding Until Reset:
      • Keep the reset button pressed until you see a change in the display or until the boiler goes through its reset sequence. This may take a few seconds.
    6. Release the Reset Button:
      • Once the reset process is complete, release the reset button.
    7. Monitor the Boiler:
      • Observe the boiler’s operation to see if the issue has been resolved. Check for any error codes or fault indicators.

    FAQs

    Do Ferroli still make boilers?

    Italian boiler manufacturer Ferroli has been at the leading edge of heating appliance design and development for more than half a century and now operates in over 100 countries worldwide.

    Why won’t my Ferroli boiler fire up?

    If your boiler is failing to fire up and just going into lock-out, it can be a problem with the PCB (printed circuit board), but you can check this by testing with a vault meter to see if electricity is reaching the PCB whilst still remaining unresponsive.

    What pressure should my Ferroli boiler be?

    Your boiler gauge should show that the boiler pressure is between 1.0 and 2.0. If the pressure drops below 1.0, then you’ll need to repressurise it.
