manual input allows an additional coffee beverage to be
prepared.
All the coffee and milk drinks are dispensed via a spe-
cially designed combination spout which also enables per-
fect milk froth and hot milk to be prepared.
The height-adjustable spout can accommodate cup heights
from 70 to 140 mm. The front door is also height-
adjustable to enable jugs up to a height of 280 mm to be
filled without any difficulty.
Each portion is freshly brewed at the touch of a button to
guarantee high quality for your beverages.
The machine user guide is a graphic touch screen display.
By pressing lightly on particular soft keys in the display
you can activate certain machine functions or call up in-
formation.

3Warnings
Maximum machine safety is an integral WMF beverage characteristic to which we pay particular
attention.
In spite of all our safety precautions however, every machine is potentially hazardous if not oper-
ated properly.
This is why – for your own safety – we have summarised the warnings below and highlighted
them in grey throughout the instruction manual.
Please also follow the “Safety instructions” on page 88.
For your own safety,
please observe the
following instructions
Connection of the machine to site services and starting up for the
first time must only be carried out by WMF customer service
technicians.
at all times: All maintenance and repair work must only be carried out by
WMF customer services, using original parts.
In no circumstances should the safety devices fitted be tam-
pered with. Never remove any machine body parts.
Caution! Scalding hazard!
In the dispensing area for coffee 7, hot water 11 and steam 8there
is a scalding hazard.
Take care when the spout or front door is raised: always make sure
a cup is in position before dispensing any beverage.
Caution! Health hazard!
Follow the instructions on the pack when using the cleaning
beverage. The cleaner is corrosive. Cleaning fluid flows out of the
combination spout 7while cleaning is in progress. Wait until
prompted by the display before placing cleaning tablets in the

4Safety instructions
General notes
1. At the end of the working day always ensure that the shut-off device on the water pipe supply-
ing the machine is closed and the main power switch to which the machine is connected is
switched off and/or the plug is removed from the socket.
2. The component-tested safety devices fitted, prevent inadmissable pressure and temperature
rise in the boiler. If the safety valve is activated, the machine should be switched off immedi-
ately at the customer’s main switch. Switch off the machine if a boiler malfunction occurs.
Contact the WMF customer service department and do not switch the machine on again until
the fault has been remedied.
3. This machine is not for use out of doors. In case of freezing the machine should be drained
beforehand to prevent frost damage.
4. Never spray the machine with a hose or steam jet. Clean the surface by wiping with a damp
cloth, or use beverages from our WMF care range.
5. The unit must stand safe at a ground level, on a horizontal and stable base.
Machine shutdown – holidays
1. If the machine is to be shut down for an extended period, a general cleaning should be carried
out beforehand and the grouts collector must be emptied. If there is any risk of freezing, the
machine should be drained beforehand to prevent frost damage. In such cases, call in the
WMF customer service personnel in good time.
2. After several weeks of shutdown for holidays, we recommend that the fully automatic cleaning
program be run at least twice before the machine is started up again.
Hot water boiler data - see rating plate
The hot water boiler complies with the Pressure Equipment Directive 97/23/EC – Category 1,
Module A.
The hot water boiler is subject to neither notification nor licensing. Each hot water boiler is sub-
jected to hydrostatic tests before delivery to the customer.
The German regulation governing steam boilers and the associated technical rules require the
owner / operator of such plants to ensure that the safety facilities are carefully serviced and in-
spected.
The machine / unit complies with all the relevant regulations.
The owner / operator must ensure that the electrical equipment and systems are in safe working
order.

89
This device is subject of the directive on waste electrical and electronic equipment
(WEEE/EU directive) and may not be disposed of as domestic waste. Please contact
your WMF Customer Service for information on proper disposal of the device.
Preventive measures to avoid consequential machine damage
Any technical device, particularly large fully automatic machines, are a potential source of
danger when operated without supervision.
We therefore recommend that the operator takes appropriate action to prevent damage, for
instance installing a suitable water detector in the site water supply line.
If the local water has a carbonate hardness of more than 5° (German hardness), a WMF water
filter must be installed in the supply line to the machine.
Maintenance intervals depend on how heavily the machine is used and on local water condi-
tions, and should be fixed by agreement with your service engineer. Even in the case of light
use, maintenance should be carried out at least once a year and the water filter, if fitted, should
be replaced.

WMF auxiliary cooler or Tetra Pak).
Always make sure the milk tanks are topped up or replaced
in good time, to ensure correct operation of the coffee ma-
chine.
7.4 Beverage key selection and labelling
Depending on the machine version chosen, you have either
5 or 9 beverage keys and one hot water key at your dis-
posal (shown here: control panel 5with 9 beverage keys
17). You can assign each beverage key 17 individually
with your chosen coffee beverages. Around 40 pre-set
standard beverages are provided for you (see chapter 8.2.8,
page 121) or alternatively you can choose your own set-
tings.
You can label the individual beverage keys 17 with differ-
ent beverage symbols which your local WMF customer
service engineer can replace according to your require-
ments.
The 2x key gives you access to a second level of keys.
