JURA Espresso Machine Error Codes Explained
22 JURA codes and display messages, transcribed from JURA's own manuals and support pages. 21 have a published meaning and at least one user-serviceable step, so they get a full page; the rest are listed here because you may see them, but JURA does not publish what they mean and we will not invent it.

When to stop and call a technician
- The machine trips a breaker, smells of burning, or shows scorched wiring.
- Water is leaking from inside the chassis rather than from the tank, tray or portafilter.
- The fault involves the boiler, a pressure valve, the heating element or the pump itself.
- The code returns immediately after a correctly completed reset or maintenance cycle.
- The machine is under warranty — opening it yourself usually ends that cover.
Never bypass, disable or remove a safety device — a thermal fuse, pressure relief valve or lid interlock is the part standing between a fault and a fire. Do not open a pressurised boiler or work on mains wiring.
