Espresso Machine Error Codes and Troubleshooting
114 codes and messages across 5 brands, plus 14 machine-agnostic faults. Every meaning and every fix step is transcribed from the manufacturer's own manual or support page, and each one cites the document it came from. Where a manufacturer prints a code but never defines it, we say so instead of guessing.

Sources are official manufacturer manuals and support pages only. Forums, repair blogs and video channels are not used as sources of record for a code's meaning or its fix — a wrong fix costs someone a boiler. We do not repair machines, and every page tells you plainly where the do-it-yourself path ends.
