Answer: What Does My Boiler Error Code Mean?

Modern boilers display error codes on their digital display to indicate specific fault conditions. Common codes include: E01 or similar for ignition failure, E02 for flame loss during operation, E10 for low water pressure, E20 for overheating, and E50 for pump circulation issues. The exact code and meaning varies by brand — Navien, Viessmann, Baxi, IBC, NTI, Rinnai, and Bosch each use their own code system. Refer to your boiler manual for the specific code chart. While error codes point to the general area of the problem, professional diagnosis with manufacturer-specific diagnostic tools is needed to identify the exact cause.
