2024 Ferroli Boiler Error & Fault Codes
Error codes can be a frustrating inconvenience if you’re not prepared for them. However, knowing a little bit more about what each one means can be quite valuable when you have a limited time to diagnose the issue. Understanding what your error code means is the best way to ensure that you get your boiler back up and running in no time – without incurring unnecessary expenses.
When your Ferroli boiler displays a fault code, the first step is to determine what it means. Codes can be long and abbreviated with many characters, and these can sometimes be confusing for customers. Our table breaks down all the most common codes into a simple searchable column, enabling you to quickly identify the problem.
If your Ferroli boiler is giving you a fault code, there’s something wrong. These error codes can sometimes be hard to decipher – so we’ve provided a comprehensive guide for you to check against your own boiler to tell you exactly what the problem is. With this information you can contact your local engineer to fix it, or get some free quotes to compare direct.
