Why does my Jura Coffee Maker only drip coffee when brewing?
- T
  tcopelandJul 25, 2025
  If your Jura Coffee Maker only dispenses coffee in drips during preparation, it might be because the coffee is ground too finely, obstructing the system. To resolve this, adjust the grinder to a coarser setting. Alternatively, the water hardness may not have been correctly set, in which case, perform descaling.

What to do if the & or ! symbol lights up and other symbols flash on Jura ENA 4 Coffee Maker?
- B
  Bridget RobinsonAug 9, 2025
  If the '&' or '!' symbol lights up brightly and other symbols flash on your Jura Coffee Maker, it could be due to the machine being exposed to cold temperatures for an extended period. In this case, the heating function may be disabled for safety. To fix this, warm the machine at room temperature.
