Jura Error 8
After the grinding process is complete, the coffee grounds enter the Brew Group. The Gear Motor is activated by the Encoder , a sensor that relays the signal from the CPU to initiate the brew process. The Gear Motor engages the Brew Group Guide, activating the Brew Group Infuser to compact the coffee. The Piston Gasket creates an airtight seal, allowing pressure to build to its optimal level, thus beginning the Brew Cycle. The pressure creates the thick layer of crema on top of espresso shots. When the coffee is finished brewing, the Brew Group dumps the used grounds into the Coffee Grounds Container and returns to its stationary position.
If your Brew Group is nearing the end of its life, then you will hear the Brew Group struggling to obtain the correct position, or notice the coffee grounds are watery when dumped into the Used Coffee Container. Replacing gaskets and lubricating the Brew Group every 6 months will dramatically increase the life of the Brew Group.
Most importantly, it is imperative to service the Brew Group every 6 months to a year to eliminate mold that accumulates inside the Brew Group. Mold poses a health risk and should not be an added ingredient in your espresso. We have seen mold growth in multiple machines that were less than two years old.
