8 - Brew Group is not
correctly positioned. This is the most frequently
occurred error on all Jura Capresso machines.
Lack of brew group maintenance.
Brew group needs to be refusrbished i.e. replace piston seals
and thorough lubrication.
8 - Brew Group encoder,
a device that controls the upward and downward movenemt during
brewing, is defective.
8 - Brew Group drive
motor does not move; machine makes loud clicking
repair or replace brew group
Check encoder cable or replace
encoder if necessary
Brew Drive motor not correctly
installed after replacing the brew group. The brew drive
motor pinion is not alighned with the brew group
guidance. Replace brew drive motor or re-install
- Blockage or leakage in the fluid system
Isolate the leakage
or blockage inside the machine. Replace seals and
o-rings to prevent from recurring. It's a recommended
exercise to descale the machine. Seals and o-rings get
hardened due to calcium sediment and cause leakage in the
- Grinder not grinding coffee beans and times out due to
blocked ground coffee passage
Grinder burrs are
Clear the coffee
passage to the brew group. Coffee passage is blocked due
