Baxi Boiler Problems and Fault Codes

There is no denying that Baxi boilers work extremely well, but occasionally they can develop a problem. When there’s an issue with your Baxi boiler it will display a fault code.

You can use this fault code to determine the problem, speeding up the process of working out what’s wrong and how it can be fixed. With Baxi boilers, all fault codes begin with the letter E. If the code does not begin with the letter E, there’s nothing to worry about and this code is simply showcasing a status for the boiler and how it’s operating.
