3 Preparing and using for the first time
When setting up your E6, please note the following:
UPlace the E6 on a horizontal surface that is not sensitive to
water.
UChoose a spot for your E6 which protects the machine against
overheating. Ensure that the ventilation slots are not covered.
Coffee beans which have been treated with additives (e.g. sugar),
ground coffee or freeze-dried coffee will damage the grinder.
T Only use roasted, untreated coffee beans to fill the bean
container.
T Remove the aroma preservation cover.
T Remove any dirt or foreign objects from inside the bean
container.
T Fill the bean container with coffee beans and close the aroma
preservation cover.
When you use the machine for the first time, you must set the water
hardness. If you do not know the hardness of your water, you can
find this out first. Use the Aquadur® test strips supplied with the
machine.
T Hold the test strip under flowing water for one second. Shake
off the water.
T Wait for about 1minute.
T You will then be able to read the degree of water hardness from
the discoloration of the Aquadur® test strip and the description
on the packaging.

Your E6 creates fine, creamy, feather-light milk foam with a perfect
consistency. The most important requirement for frothing milk is
a milk temperature of 39–46 °F (4–8 °C). We would therefore
recommend using a milk cooler or a milk container.
T Remove the protective cover from the fine foam frother.
T Connect the milk pipe to the fine foam frother.
EYour E6 is equipped with the HP1 milk system.
T Connect the other end of the milk pipe to a milk container or a
milk cooler.
Your E6 can be connected with your JURA app (J.O.E.®).
Requirement: J.O.E.®is installed on your mobile device. The
optionally available JURA WiFi Connect is inserted into the service
socket of your E6.
For more information about setting up the WiFi Connect, please go
to jura.com/wifi or scan the QR code.

Hot coffee, hot steam and hot water can cause scalding. Scalding
is a serious burn.
T Use extreme care when handling hot liquid or steam.
T Allow liquid to cool down before drinking.
T In the event of scalding, rinse affected area with cold water and
seek medical attention.
T Keep children AWAY.
Basic information about preparing drinks:

Change the coffee strength of a single product Press the 9or 0button during grinding
Change the amount for a single product Press the 9or 0button during preparation
EThe longer you press the 9and 0buttons, the faster your
setting changes.
Aim What to do

Coffee tastes best served hot. A cold porcelain cup cools the
beverage – and impairs the taste. We therefore recommend
prewarming the cups. You can purchase a JURA cup warmer from
your specialized dealer.

For the ‘caffè Barista’ and ‘lungo Barista’, blend the coffee with
hot water. This results in a full-bodied specialty coffee which is
particularly easy to digest.

‘Close switch’
T Turn the switch to the °position.
You can choose to use a second coffee variety, for example
decaffeinated coffee, with the filter funnel for ground coffee.
Basic information about ground coffee:
UNever add more than two level measuring spoons of ground
coffee.
UUse ground coffee which is not ground too finely. Very fine
coffee can block up the system so that the coffee only comes
out in drips.
UIf you did not fill the machine with a sufficient amount of
ground coffee, ‘Not enough ground coffee’ is displayed and the
E6 stops the operation.
UThe desired specialty coffee must be prepared within
approximately one minute after filling with the ground coffee.
Otherwise the E6 stops the operation and is once more ready
for use.
UAll specialty coffees with ground coffee are always prepared
following the same model.
Example:Proceed as follows to prepare an espresso using ground
coffee.
T Place an espresso cup under the coffee spout.
T Press the fbutton for two seconds to call up Specialty
