Brew unit for Jura Micro / A coffee machines

The Jura 70173 brew unit is an original spare part for Jura ENA Micro and Impressa A series fully automatic coffee machines. If your coffee machine displays error 8 (Störung 8), makes loud unusual noises when moving the brew group, water leaks into the drip tray, or coffee flows very slowly, the cause is typically a worn brew unit. This part solves all these problems – it is fully assembled, ready for immediate replacement and will restore full functionality to your coffee machine.

When does this part need replacing? (Fault symptoms)

The brew unit typically fails when you see any of these symptoms:

• Coffee machine displays error 8 (Störung 8) – brew group is not in correct position, cannot return to home position
• Water leaks into drip tray or under the coffee machine instead of flowing through the coffee
• Coffee flows very slowly, dripping, or does not flow at all even though the machine is working
• Coffee machine makes loud unusual noises (grinding, hissing sound) when moving the brew group, as if something is stuck
• Ejected coffee puck is wet, falls apart and is not a firm dry puck – this indicates pressure loss
