Jura coffee machines are known for their elegant design, high-end features, and ability to deliver barista-quality coffee with the push of a button. Among their popular models, the Jura E6 stands out as a user-friendly, fully automatic coffee machine perfect for everyday home or office use. While Jura machines are built for durability and performance, they may occasionally encounter issues. Here are some of the most common problems Jura users face and how to fix them.
1. Machine Not Dispensing Water
Cause: This issue can be due to air trapped in the system, a clogged water filter, or scale buildup in the internal tubing.
Fix:
- Ensure the water tank is full and properly inserted.
- Remove or replace the CLEARYL Smart filter if clogged.
- Run a hot water cycle to push out trapped air.
- Perform a descaling cycle using Jura-approved descaling tablets.
2. Error Code 22 – Grinder Malfunction
Cause: This error (Error Code 22) indicates the grinder is jammed or the grinder motor isn’t functioning correctly. This may be due to a foreign object (like a stone) in the coffee beans or lack of cleaning.
Fix:
- Turn off and unplug the machine.
- Check the grinder for any blockage or debris.
- Clean the grinder area gently with a soft brush or vacuum.
- If the error persists, contact Jura service as the motor may need replacement.
3. Coffee Not Hot Enough
Cause: Over time, mineral deposits can reduce heating efficiency, or the machine may not have had enough warm-up time.
Fix:
- Always allow the machine to preheat before brewing.
- Descale the machine regularly to remove mineral buildup.
- Use warm cups (preheated with hot water) to maintain beverage temperature.
4. Weak or Watery Coffee
Cause: This can be caused by a low strength setting, grinder set too coarse, or using stale coffee beans.
Fix:
- Increase the coffee strength setting in the menu.
- Adjust the grinder to a finer setting (only during grinding).
- Use fresh, high-quality coffee beans.
5. Coffee Grounds in Cup
Cause: This usually means the brew group is dirty or the internal seals are worn out.
Fix:
- Run a cleaning cycle with Jura cleaning tablets.
- Clean the drip tray and internal brewing unit regularly.
- If the issue continues, the brew unit may need servicing or replacement of seals.
6. Touchscreen or Buttons Not Responding
Cause: Electrical glitch, moisture on the control panel, or a faulty circuit board.
Fix:
- Restart the machine and unplug it for a few minutes.
- Wipe the screen or buttons with a dry cloth.
- If unresponsive, contact Jura support for diagnostics.
Final Thoughts
Jura machines like the E6 are built to last and deliver excellent coffee consistently, but like any appliance, they require proper maintenance and care. Regular cleaning, descaling, and using quality beans can prevent many common problems. If issues persist, it’s always best to reach out to Jura’s official customer support or an authorized service center.
