When it comes to keeping our home warm and comfortable, boilers play a crucial role, especially during the colder months. However, like any other household appliance, boilers can experience technical issues that often manifest through error codes. These codes are a way for our Ferroli boiler to communicate to us what is going wrong within its system. Understanding these codes can be the difference between a quick fix and enduring days without heating.
To help you navigate these moments of uncertainty, at codigodeerror.com, we have prepared a comprehensive table of error codes specific to Ferroli boilers. Before diving into it, let’s clarify some concepts that might seem a bit technical but are essential for a better understanding of what your boiler is trying to tell you.
Error codes: These are alphanumeric sequences displayed on your boiler’s control panel when it detects a problem in its operation. Each code is associated with a specific issue.
Ionization electrode: This is a component of the boiler that detects if there is a flame present to ensure safe operation. If this fails, your boiler might not ignite.
Heating sensor: This sensor measures the temperature of the water within your heating system to ensure it stays within safe and efficient ranges.
ABM03 control unit: This is the “brain” of your boiler, an electronic board that controls and manages the operation of the boiler.
With these concepts in mind, we present to you the table of error codes for Ferroli boilers. This information will allow you to quickly identify the problem and, in many cases, provide you with a solution that you can perform yourself before considering calling a technician.
| Error | Description | Cause | Solution |
|---|---|---|---|
| A01 | The burner does not ignite | – Lack of gas – Anomaly in the detection or ignition electrode – Gas valve damaged – Ignition power too low | – Check that gas is correctly reaching the boiler and that there are no air in the pipes – Check that the electrode is well placed and connected, and that it does not have incrustations – Check the gas valve and replace it if necessary – Adjust the ignition power |
| A02 | Flame signal present with burner off | – Electrode anomaly – Card anomaly | – Check the ionization electrode wiring – Check the card |
