Preparing and using for the first time
Preparing and using for the first time
When setting up your E8, please note the following:
UChoose a spot for your E8 which protects the machine against
overheating� Ensure that the ventilation slots are not covered�
UPlace the E8 on a horizontal surface that is not sensitive to
water�
Coffee beans which have been treated with additives (e�g� sugar),
ground coffee or freeze-dried coffee will damage the grinder�
TOnly use roasted, untreated coffee beans to fill the bean
container�
TRemove the aroma preservation cover�
TRemove any dirt or foreign objects from inside the bean
container�
TFill 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�
THold the test strip under flowing water for one second� Shake
off the water�
TWait for about 1minute�
TYou 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�

from your specialized dealer�
Press the fbutton for two seconds to initiate Specialty Selection:
Specialty Selection Meaning
‘Extra Shot’ s
(cappuccino, flat white,
latte macchiato)
The product is prepared with two
brewing operations, each with half the
amount of water – for a specialty
coffee with a particularly intense taste�
‘Ground coffee’ £The product is prepared with ground
coffee�
EIf you press your preselection briefly, the next product will
be prepared according to your preselection�
EIf you press and hold your preselection (for two seconds), the
preselection will be active until you switch off your E8�

Preparation
TPlace a glass under the fine foam frother�
TPress the ‘Latte Macchiato’ button�
The preset amount of milk foam flows into the glass�
EThere is a short interval while the hot milk separates from
the milk foam� This allows the typical layers of a latte
macchiato to form�
The preset amount of water for espresso flows into the glass�
To ensure that the fine foam frother always works properly, you must
clean it daily when you have been preparing milk (see chapter 7
‘Maintenance – Cleaning the milk system’)�
For the ‘Caffè Barista’ and ‘Americano’, the E8 blends the coffee with
hot water using a special preparation method� This results in a
full-bodied specialty coffee which is particularly easy to digest� You
can change the amount of this additional water (see chapter 4
‘Preparation – Adjusting the product settings’)�
‘Doppio’ is Italian for ‘double’� When you select Espresso doppio,
two espressi are prepared one after the other� The result is an extra
full-bodied and aromatic specialty coffee�
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
E8 stops the operation�
UThe desired specialty coffee must be prepared within
approximately one minute after filling with the ground coffee�
Otherwise the E8 stops the operation and is once more ready
for use�
UAll specialty coffees with ground coffee are always prepared
following the same model�
