What are boiler fault codes?

Boiler fault codes are alphanumeric codes displayed on the control panel or digital display of a boiler. These codes are generated by the boiler’s internal diagnostic system and are used to indicate specific faults or issues that the boiler has detected. They serve as a troubleshooting tool for both homeowners and heating engineers to identify and diagnose problems with the boiler.

Each boiler manufacturer has its own set of fault codes, and the meaning of the codes can vary between different models and brands. When a fault occurs, the boiler will display a specific code that corresponds to the detected issue. It can be a combination of numbers, letters, or a combination of both.
