2 General description
The WMF Bistro easy coffee machine is a fully
automatic single-cup machine for making Espresso,
Café Crème, Cappuccino, White Coffee and Latte
Macchiato. Hot water dispensing is also possible.
Both coffee beans and ground coffee can be used,
coffee beans via the grinders and ground coffee via
the manual input.
All the coffee and milk drinks are dispensed via a
specially designed combination spout, which also
enables perfect milk froth and hot milk to be
prepared.
Each portion is freshly brewed at the touch of a
button to guarantee high quality for your beverages.
Take it easy!

3 Warnings
Maximum machine safety is an integral WMF product characteristic to which we pay particular
attention.
In spite of all our safety precautions however, every machine is potentially hazardous if not
operated 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 48.
For your own safety,
please observe the following
instructions at all times:
Connection of the machine to site services and starting up
for the first time must only be carried out by WMF
customer service technicians.
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
tampered with.
Caution! Scalding hazard!
In the dispensing area for coffee 6 and hot water 12 there
is a scalding hazard. Take care when the spout 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 product. The cleaner is corrosive. Cleaning fluid
flows out of the combination spout 6 while cleaning is in
progress.
For machines with no drain connection, a container
(capacity at least 1.4 litres) must be put in place to collect
the cleaning fluid safely.
Caution! Scalding hazard!
Never reach under the spouts while cleaning is in
progress.
Caution! Injury hazard!
When the machine is on, never put your hand into the
coffee beans hopper or brewer dispensing area.

4 Safety instructions
General notes
1. At the end of the working day always ensure that the shut-off device on the water pipe
supplying 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 inadmissible pressure and temperature rise
in the boiler. If the safety valve is activated, the machine should be switched off immediately
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.
3. Never spray the machine with a hose. Steam cleaners, steam-jet cleaners and similar
equipment must not be used to clean the machine. Clean the surface by wiping with a damp
cloth, or use products from our WMF care range.
4. 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 clean should be carried out
beforehand and the grouts container 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
subjected to hydrostatic tests before delivery to the customer.
The owner / operator of such plants must ensure that the safety facilities are carefully serviced and
inspected.
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.
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.
49
Preventive measures to avoid consequential machine damage
Any technical devices, 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
conditions, 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.

6 Conditions for Installation and Operation
The machine operator must arrange for the site preparatory work. This should be carried out by
approved contractors in accordance with general and local regulations. WMF customer service
technicians are only permitted to connect up the machine to the prepared connections. They are
not authorised to carry out plumbing or wiring work on site and will not be responsible for such
work!

mm from the back and sides from the building or nonWMF components.
A clear height of 1100 mm from the top of the
supporting surface should be ensured. The height of
the supporting surface from the floor surface should be
not less than
700 mm and not more than 900 mm.
If the machine connections are to be routed down
through the counter, remember to also allow space for
the connections. These may restrict the available space
below the machine.

* The on-site electrical system must comply with IEC 364. An e.l.c.b. switch with 30 mA rated fault current to
EN 61008 should be installed upstream of the unit for increased safety. An earthed socket outlet must be installed
near the unit for one-phase connection. A 5-pole CEE/CEKON socket outlet to EN 60309 must be installed for
three-phase connection. If the mains power cable of this unit is damaged, it must be replaced by our customer
service engineer or a similarly qualified person. If the machine is permanently connected on site, a disconnecting
device (master switch) to EN 60947 acting on all poles and with a contact gap of at least 3 mm must be installed
upstream. The disconnecting device is also recommended for flexible connection. The mains power cable must not
be allowed to come into contact with hot parts of the machine. Master switch and socket outlet are part of the on site installation. The machine must not be installed with permanent on-site connection when mounted on a trolley.

each key press.
See page 56,
7.5.4 Quantity selection.
7.2 Filling the coffee beans hopper
To fill the coffee beans hopper 1 remove the hopper lid and
fill the hopper with coffee beans. Then replace the lid to
close the hopper. Each coffee beans hopper has a capacity
of approx. 1.1 kg.
52
It is important to refill the coffee beans hopper 1 before it
is completely empty, to ensure correct operation of the
coffee machine.
Special version (‘empty’ message):
A display 8 requests you to refill the coffee beans hopper 1.
Refill
coffee beans left!
Coffee dispensing is disabled when the coffee beans
hopper 1 is empty.
Refill
coffee beans right!
Simply refill the hopper with coffee beans and the message
will disappear.
7.3 Preparing to dispense milk
In order to dispense coffee beverages with milk from the
machine, the milk container (e.g. the Tetra Pak as shown
here) has to be connected to the combination spout 6 of the
machine by the milk intake hose.
If this is not the case, proceed as follows:
The milk intake hose has a plastic connector on one end
(bottom left in the picture) and a metal nozzle on the other
end (top right in the picture).
Insert the connector of the milk intake hose into the
connection provided on the underside of the combination
spout 6. Then push the milk intake hose into the guide on
the underside of the combination spout 6, to fasten the milk
intake hose to the combination spout 6.
