Diagnosis
This is almost always the internal thermal fuse (a safety device) blowing, often triggered by a power surge during plug-in or a failed heating element.
How to Fix It
Check the power supply method first.
1. Ensure you are plugging directly into a wall outlet, not a power strip or extension cord.
2. Try a different outlet in another room.
3. Check that the power cord is firmly connected at the back of the machine (it's removable).
If That Didn't Work
If the outlet and cord are confirmed good, the blown thermal fuse is the culprit. This is not a user-serviceable part. You must contact Jura service for repair.
Heads Up
Juras are sensitive to voltage spikes. Use a high-quality surge protector for the outlet, but plug the machine directly into that protector, not into a secondary strip.
