Is it worth repairing my Impressa S85?

Hello together,


>I got a slightly defective Impressa S85 as a present, but it's already aging. Now I ask myself whether a repair is worthwhile at all or whether the necessary money would be better invested in a new machine.


The machine is a good 10 years old. According to the internal counter, about 15,000 coffee purchases have been made so far. Except an exchange of an electronic component (unfortunately unclear which one), allegedly no maintenance or the like was carried out on the machine. The machine was mainly operated without a filter cartridge but was regularly decalcified. Further information about the machine is not known.

The defect is at the height-adjustable outlet of the machine: The coffee does not come as intended from the two "nozzles" but squeezes about 0.5cm to the side from a gap in the plastic.


>I have been able to find out so far by reading the information that in view of the advanced age of the machine, the boiler for the coffee water (costs almost 100€) is probably ready for replacement. In addition there would be the exchange of all seals (approx. 20€).

I would do the repairs myself.
(I have already done a successful tinkering on another Jura machine. My question is now whether, in your opinion, further parts of the machine would have to be replaced with certainty now or in the foreseeable future, or whether this is likely to be the case. Do you have any experience on how old Jura Impressa S85 machines (or their components) generally get?


I would appreciate your advice.


Many greetings

Always worth it, in my opinion. With 15000 covers one should keep an eye on the grinder. Possibly replace the grinding cones.
Clean the outlet, then the coffee will run out again where it should.
Heating is available for 75€. It's best to open it first and see what's still due. At the hose plug of the height-adjustable spout, the holding nose sometimes breaks off.
detection springs additional etc.

"Revise" the brew group, so put new gaskets in. There are lots of instructions...
Dismantle coffee spout at best, soak and clean...
Replace boiler only when it is broken. Exchanging on suspicion is exaggerated...
A few pressure hose seals will probably leak/become leaky because the rubber has hardened. It is best to buy 10 additional pieces and then exchange them all on suspicion. Cost only small money and save trouble...

Thank you Schlawi and Danceman for your answers and sorry for the late reaction, had a stressful weekend.

I will follow the advice regarding brewing group and changing seals. And of course, clean the inside of the machine thoroughly.

The retaining lug on the hose connector that goes to the height-adjustable outlet only has to be replaced if it breaks off during removal or installation, or?

What do the detection springs do? Should I trade them too? Or at least order at the same time?

The coffee comes out of the machine at 75 °C. So I guess I should replace the boiler, right?

Can the replacement of the grinding cones be carried out correctly by myself with the appropriate instructions? I have read that the entire grinding mechanism should always be replaced, because only the manufacturer can achieve the ideal alignment of the grinding cones and thus the correct composition of the coffee. Is it true? Or do you get a good result yourself?

Many thanks for your helpful answers!

Good evening,

the steel grinding cones do, however, wear off over time. But if the grinder is nicely cleaned and adjusted properly, the coffee will also be decent, unless the cone and the grinding ring are really blunted. The manufacturers want to sell new grinders. The grinder is not difficult to adjust. First observe the 3 markings. They must be on the run again by the end of the day. If necessary, redo the markings with a suitable pen. Turn the adjusting ring counterclockwise as far as it will go. Then the outer grinding ring goes out. When cleaning, proceed in reverse. From the stop clockwise until the markings are in one line.

Hello, if the grinder does not supply any granulated sugar-like grinding/pomace in the basic setting, you can set it a little narrower and move the adjustment lever back to the middle position.
Up to three holes it's okay, if it's more, then the grinder is blunt, either new stones or grinder.
Depending on the manufacturer, different stones are used. And Jura still has Aroma+ and they're pretty expensive.

MfG Chris

It can also be fastened with a small cable tie. But if you order something you can also order the part...

I suppose you mean the plates that recognize if the shell is inside or the shell is full? You don't have to replace them. When they don't work properly, they cleanse miracles. The copper oxidizes and then there is no proper contact...

In principle not. The temperature is controlled by a sensor. As long as the heater is still working, it does not need to be replaced. Just decalcify again. Sometimes this brings something because lime is a bad heat conductor...
