If your Jura coffee machine shows the symptoms we describe below, it is time to replace the brew unit.
When is it necessary to replace the brew unit? (Fault symptoms)
The brew unit typically fails when you see one of these symptoms:
- Coffee machine displays error 8 (Error 8, Störung 8) – brew unit is not in the correct position and the machine refuses to operate
- Coffee machine makes unusual mechanical noises during brew unit movement, sounds resembling a sucking noise or the "death rattle" of the coffee machine
- Water goes into the drip tray or into the ground coffee container instead of forcing through the coffee – a sign of pressure leak
- Coffee flows very slowly, in a weak stream or in drops, because the worn unit cannot generate the necessary pressure
- Coffee puck is wet, crumbly and not compact – the unit cannot properly compress and force the coffee through

Jura coffee machine – Error 8 (Störung 8)
Why does my Jura coffee machine show Error 8?
Error 8 (Störung 8) means the brew unit is not in the correct position.
Typical symptoms:
- Coffee machine does not brew coffee
- Loud noise resembling a drill
- Error message appears repeatedly
The problem develops gradually – first occasional messages, later complete failure. In most cases, the cause is a worn brew unit that cannot return to its home position.
After replacing the brew unit, Error 8 disappears and the coffee machine operates quietly and reliably again.
