REF: https://www.jura-parts.com/Jura-A-C-E-F-J-S-X-Z-GIGA-ENA-Encoder-p/10008.htm In the description of the ENA Encoder (see reference link above) it says, "The encoder counts the number of revolutions required by the gear motor to compact the coffee. If the correct amount of revolutions is not met, then a "Fill Beans" message may appear. If you are experiencing a problem during this process, then inspect the teeth on the Gear of the Gear motor first. Encoders do fail, but not often." If there is a problem with the teeth on the gear motor, you can can buy a new gear here: https://www.jura-parts.com/Jura-Impressa-C-E-F-J-S-X-Z-ENA-Brew-Drive-Gear-p/10037.htm. If however, the teeth are fine, then look to replace the ENA Encoder since it counts the revolutions to stop the compact process.
