Step-by-step repair guide

Step 1

These instructions apply to nearly all fully automatic coffee machines from Jura, as well as similar models from AEG and Krups. The improvement after replacing the grinder burrs is remarkable!

The photo shows the worn grindstones on the left and the new ones on the right. Each set consists of a grinding ring (the stationary burr) and a grinding cone (the rotating burr). When sourcing replacements, a complete Repair kit for coffee grinder for Jura coffee machines includes both components.

For this repair, the side panels do not necessarily have to be removed.

Step 2

Pull the grinder adjustment dial straight up. Note the current setting — it is best to take a photo so you can restore it after reassembly.

The screws securing the bean hopper are recessed in two cavities. Clean any coffee residue from the recesses first, then loosen the screws. The protective cover over the grinder assembly does not need to be removed. To access the machine's housing, you will need an Oval head bit for opening Jura fully automatic coffee machines.

Conclusion

Follow the steps in reverse order to reassemble your machine. After reassembly, restore the grinder adjustment dial to its original position and run a few test grinds to verify consistency. It is also a good practice to run a cleaning cycle with 3-phase cleaning tablets for Jura coffee machines once everything is back together.

Frequently Asked Questions

Will replacing the grindstones really make a noticeable difference in my Jura Impressa's performance?

Yes — worn burrs produce an inconsistent grind, which directly affects extraction and brew quality. Replacing the grinding ring and grinding cone restores a uniform particle size, resulting in noticeably improved espresso flavour. You can find the replacement grinder repair kit for your Jura Impressa C, E, or F model at Brewive.

Do I need to fully disassemble my Jura machine to replace the grindstones?

No, you do not need to fully strip the machine. The side panels do not necessarily have to be removed, and the protective cover over the grinder assembly can remain in place, making this a relatively straightforward repair. Brewive carries the replacement grindstones you need to get started.

Will this grindstone replacement work on my AEG or Krups coffee machine, or only on Jura models?

This procedure applies to nearly all Jura fully automatic machines as well as comparable models from AEG and Krups that share the same grinder design. Check Brewive for compatible grindstone replacements that fit your specific machine model.

What parts are included in a grindstone replacement, and where can I get them?

A grindstone replacement consists of two components: a grinding ring (stationary burr) and a grinding cone (rotating burr). Both wear down over time and should be replaced together for optimal grind uniformity. You can source high-quality replacement grindstones for your Jura Impressa C, E, or F model from Brewive.

Should I note my grinder settings before starting the replacement?

Yes — it is essential to record the grinder adjustment dial position before pulling it up. Taking a photo of the current setting ensures you can restore it accurately after the repair. Brewive provides the replacement parts and resources to help ensure your grindstone replacement goes smoothly.
