Introduction
Thank you for purchasing the IMPRESSA E10/20/25. To ensure
perfect functioning of your IMPRESSA E10/20/25, carefully read
this operating manual and keep it for future reference.
Should you need more information or if you encounter particular
problems not specified in these operating instructions in sufficient
detail, either contact us directly or contact your local authorized
dealer.
You will also find useful tips on operation and maintenance
of your IMPRESSA E10/20/25 on the website at
www.jura.com.
1. Safety information
1.1 Warning
Children do not realize the dangers involved in using electric
appliances, for this reason always keep an eye on children when
they use electric appliances.
The coffee machine may only be used by instructed persons.
Never use a defective coffee machine or a machine with a
defective mains cable.
Never immerse the coffee machine in water.
1.2 Precautions
Never expose the coffee machine to weather (rain, snow, frost),
never touch the machine when your hands are wet.
Place the IMPRESSA on a firm, level base that is resistant to
any water that may leak. Never stand on hot or warm surfaces
(oven hobs). Keep out of the reach of children.
If you don’t use the machine for a longer time (holidays, etc.)
always disconnect the mains cable.
Always disconnect mains cable before cleaning the machine.
When disconnecting the mains cable never pull on the mains
cable or the machine itself.
Never repair or open the coffee machine yourself. Any repairs
may only be carried out by authorized service shops using
original spare parts and accessories.
The coffee machine is connected to mains supply via a mains
cable. Make sure nobody can trip over the mains cable. Make
sure children and pets cannot reach the machine
Never put the coffee machine or individual parts of it into a
dishwasher.
Make sure to install the machine at a place with sufficient air
circulation, to prevent overheating of the machine.
2. Preparing the IMPRESSA E10/20/25
2.1 Check supply voltage
The IMPRESSA E10/20/25 is preset in the factory to the correct
mains voltage. Check if your local mains supply voltage complies
with the information given on the type plate on the underside of the
IMPRESSA E10/20/25.
2.2 Check electrical fuse
The IMPRESSA E10/20/25 is designed for an electric current of 10
amperes. Check if the electrical fuse has sufficient capacity.
2.3 Fill water tank
Only use fresh, cold water. Never fill in milk, mineral water
or other liquids.
Remove the water tank and rinse it with cold tap water
thoroughly (Fig. 4).

7
Then fill the water tank and reinstall it. Make sure to install the
tank properly, it must engage audibly.
2.4 Fill coffee beans
To ensure that your machine will work perfectly for a long
time and to avoid damage, please note that the grinding gear
of your JURA coffee machine is not suitable for coffee beans
which were treated, during or after roasting, with additives
(e.g. sugar). Such coffee blends may damage the grinding
gear. Any repair costs resulting from the use of such blends
are not covered by warranty.
Open the bean tank cover (10) and remove the aroma preser-
vation cover (11).
Remove any dirt or foreign matter from the bean tank.
Fill coffee beans in the bean tank and close the cover.
2.5 Adjusting the grinding gear
You can adjust the grinding gear to the roast of your coffee. We
recommend
a fine grinding degree for bright roasts (the smaller the dots,
the finer the grinding)
a coarse degree for dark roasts (the larger the dots, the
coarser the grinding)
The grinding degree may only be adjusted while the grinding
gear is running.
Open the bean tank cover (10) and remove the aroma preser-
vation cover (11).
To adjust the grinding degree, turn the rotary switch (Fig. 2) to
the required position.
2.6 Power switch
Actuate the power switch (19) on your IMPRESSA
E10/20/25 before using the machine for the first time.
We recommend that you switch off your IMPRESSA
E10/20/25 with the power switch (19) if you intend not to
use the machine for longer periods of time (e.g.during holi-
days).
3. First use
Upon first commissioning or after a service, the system
needs to be filled. The system filling operation works prop-
erly only if NO Claris plus filter is inserted. Please do not
insert it before the system is filled and
lights up.

4. Setting the water hardness
Your IMPRESSA E10/20/25 heats up water. As a result, cal-
cification occurs during normal use, and this is indicated
automatically. Before using the IMPRESSA E10/20/25 for
the first time, it needs to be set to the hardness of the water
used. Use the supplied test sticks for this.
1° German hardness is equivalent to 1.79° French hardness.
The water hardness programming function is no longer
displayed if the filter has been activated.
The IMPRESSA E10/20/25 has 6 hardness degrees to select
from which are displayed while you are setting the water
hardness on your machine.

ground, vacuum-packed coffee. Never fill in more than 2
portions of powder. The pre-ground coffee tank is no storage
tank. Make sure that the pre-ground you use is not too fine.
This may cause blocking of the system. In this case the
coffee only drips out of the coffee spout.
If you have filled in too little powder, the symbols will
flash alternately for a short period of time. Your IMPRESSA
E10/20/25 stops the process. Restart the process.
You can stop the process of making coffee at any time by
pressing key (5) or (3).

cluded in your Welcome Pack. Do not replace the re-
placeable steam/hot water jet (13) directly after drawing off
steam, because the jet is hot after the draw-off operation.
Steam can be used for heating liquids and frothing milk for
cappuccino. Make sure that the replaceable steam/frothing jet
(13) is pushed upwards when liquids are heated. Push down
the frothing aid to froth liquids.
During frothing some water will escape the system before
the actual frothing process. This does not affect the result,
e.g. when frothing milk.

18. De-scaling the IMPRESS E10/20/25 upon
display request
During operation, your IMPRESSA E10/20/25 will calcify.
The degree of scaling depends on the hardness of the water
in your region. Your Die IMPRESSA E10/20/25 will inform
you when de-scaling is required. You can still draw off
coffee or hot water/steam. However, we recommend that you
should de-scale the machine (Chapter 18) within the next
few days.
JURA de-scaling tablets which are specially designed for the
de-scaling program of your IMPRESSA E10/20/25 are avail-
able at your authorized dealer. Please note that machine de-
fects or residues in the water cannot be excluded if you use
inappropriate de-scaling agents.
If the IMPRESSA E10/20/25 needs de-scaling, the corres-
ponding message is displayed.
You can still draw off coffee or hot water/steam and start the
de-scaling program later.
When using the de-scaling agent, immediately remove any
splashes or drips from sensitive surfaces, i.e. natural stone
and wooden surfaces, or take appropriate precautions.
In any case wait until the de-scaling agent is used up and the
tank is empty. Never refill de-scaling agent.

20. Tips for perfect coffee
Height-adjustable coffee spout (15)
You can adjust the height of the coffee spout to the size of your
cups (Fig. 3)
Grinding degree
Refer to Chapter 2.5 «Adjusting the grinding gear».
Preheating cups
You can preheat the cups using hot water or steam. The smaller the
coffee you want to draw off, the more important preheating is.
Sugar and cream
Stirring coffee/tea will result in heat being released. Adding
refrigerated cream or milk will reduce the temperature of the coffee
significantly.
