Jura Impressa S models dispensing head revision

Введение

Like on almost all coffee machines the dispensing head van be clogged up by coffee grease, the Jura S models are no exception. Once blocked, no coffee will be dispensed by the nozzles. The coffee will run through the sides, or only one nozzle is open. You can try to clean the nozzles with a pipe cleaner, but this is not a good and long-term solution.

A revision and cleaning is not that difficult. For this purpose the machine has to be opened up.

    • Place a lever tool in the gap between the distributor and the coffee spout. Gently lift the distributor out about 8 mm alternately on the left and right.

    • The coffee outlet manifold of this unit was un-appetizingly dirty. The aroma of the coffee suffers. The coffee no longer went through properly.

    • You can pull the distributor off completely, but it is not absolutely necessary. Clean all parts well or replace if something is damaged.
