3Warnings
Maximum machine safety is an integral WMF product characteristic to which we pay particular
attention.
In spite of all our safety precautions, 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.
This is why it is important to follow the “Safety instructions” given on page 81.
Important instructions which
must be observed for your
own safety
Connection and commissioning of the coffee machine may
only be undertaken by the WMF customer service team.
Maintenance and repair work on the machine may only be
undertaken by the WMF customer service team using
original spare parts.
Installed safety devices must not be altered for any reason.
No parts of the outside of the machine should be removed.
Caution! Risk of being burned and scalded
At the spout where hot water 12 and coffee 5,16 comes out
there is a risk of being burned and scalded. Always ensure
that there is container placed under the drinks spout! Ensure
that the container is stable and do not leave it unattended.
After switching on it is possible that hot water comes out of
the hot water- 12 and coffee spout 5,16 during the warm
brewing phase. Never reach under the spouts while cleaning
is in progress.
Caution! Health hazard!
Follow the precautions on the packaging when using the
cleaning product. The cleaning granulate is an irritant.
Cleaning fluid flows out of the coffee spout 5while cleaning is
in progress. The protective panel provided should be fitted (see
picture on page 136). Do not leave jugs or cups underneath the
coffee spout 5while cleaning is taking place. Wait until
prompted by the display before placing cleaner granulate in the
brewer.
Caution! Danger of crushing!
Never put your hand into the ground coffee hoppers 2/ 7or
the granulate cleaner reservoir 8 when the machine is in use
and the power is switched on!
Caution! Electric shock hazard!
Moisture can cause short circuits. It is therefore essential not
to allow fluids to enter the inside of the machine housing .
Under no circumstances should the machine be opened up.
Never put your hand inside the machine interior or reach
inside with a tool.

81
4Safety instructions
1Always ensure that the main water tap in the supply line is closed when the machine is switched off
and that the main power switch outside the machine is off or the mains plug is disconnected from
the socket as there is a risk of water escaping from the machine.
2 The installed component approved safety equipment prevents an impermissibly high pressure or
temperature increase in the hot water boiler. If the safety valve is actuated one-time then the
machine must be switched off at the local main switch and the main stop cock on the drinking water
supply line closed. Switch off the machine if any faults arise on the hot water boiler. Inform the
WMF customer service team and do not switch on the machine again before the fault has been
removed.
3 Do not use the machine in the open air. The water system must be emptied if there is frost.
4 The device must not be sprayed with a water hose. Use of steam cleaning, steam jet devices and
similar equipment for cleaning purposes is not permitted. Clean the surface of the coffee machine
using a soft cloth or by using products from our WMF care range.
5 The device must be set on a flat, level and secure surface.
6 Do not let children near the machine!
7 Do not use the machine if it does not work properly or if has been damaged
Shutting down the machine – company holidays
1 If the machine is to be shut down for an extended period, a general cleaning should be carried out
first and the grouts collector should be emptied. Drain the machine first to prevent frost damage if
there is any risk of freezing. A WMF Customer Service Technician must be called promptly in
such cases.
2 After several weeks of shutdown for holidays, we recommend that the full automatic cleaning
program be run at least twice before the machine is started up again.
Regulations
Refer to rating plate for boiler data.
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 operator of such plants must ensure that the safety devices are carely serviced and inspected.

82
The machine complies with all the relevant regulations.
The operator must ensure that the electrical equipment and systems are in safe working order, (e.g.
BGV A3).
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.
Preventative measures against suffering damage to the machine
xThere are always operating dangers associated with every technical device, particularly from large
fully automatic machines which are operating unobserved.
xWe therefore recommend that the operator take reasonable measures to prevent damage occurring to
the machine, for example by installing a suitable water hydrant in the drinking water supply on-site.
xIf the water used in the machine has a carbonate hardness above 9°, a WMF water filter must be
fitted in the supply line. Otherwise limescale can cause damage to the machine.
xMaintenance intervals depend on how heavily the machine is used and on local water conditions, and
should be fixed by agreement with your WMF Customer Service Technician. 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.

6.5 Coffee Dispensing Options
There are various options for coffee preparation and
dispensing, depending on your machine version and the
individual beverage settings.
Machines without a 3L storage reservoir
On pressing a beverage key, the coffee beverage is
freshly brewed and dispensed directly at the coffee
spout.
xWith optional multi-brew arm
If larger quantities are required, you can use the
multi-brew arm to brew larger quantities in a storage
container or insulated jug.
 Machines with an integral 3L storage reservoir
xWithout fresh brewing
Coffee beverages are dispensed from the integral
storage reservoir. Once you have set the desired
quantity to be brewed and stored, fresh coffee is
brewed into the storage reservoir. You can then
dispense coffee from the storage reservoir by using
the beverage keys.
The machine carries out refill brewing into the storage
reservoir automatically until the desired quantity has been
replenished.
xWith fresh brewing (optional)
This machine version enables coffee beverages to be
freshly brewed and dispensed directly via the
machine spout. In this case, the freshly brewed
coffee beverage is not sent to the storage reservoir.
This allows you to dispense small quantities of coffee even
without selecting a storage step (in stand-by mode).
A further option is a small ground coffee hopper (optional,
capacity 500g) which allows you to prepare beverages
automatically using a different type of coffee such as mild
coffee (decaf).

89
6.6 Selection of Quantity of Coffee for Storage
(only available on machines with an integral storage reservoir)
Due to the design of the machine, a quantity for storage
has to be selected before coffee can be brewed in the
storage reservoir and dispensed.
The brewer unit in the WMF Cafemat 2 allows brewing
quantities of up to 0.75 litres of coffee to be prepared.
One or more brewing cycles are carried out until the
storage reservoir contains the desired quantity.
By pressing the soft key you can access a second
level, where a Selection menu can be found. On self-
service machines, first press the black area to see the
soft key. The following display appears:
Now press the soft key to select a quantity of coffee
to be prepared.
You can also access quantity selection by pressing directly
on the storage reservoir in the previous display.
Quantity pre-selections are available and can be selected
by means of the soft keys:
6.6.1 Automatic Quantity Control
There is a choice of two alternatives: half full or full.
Half Full
1.5 litres of coffee are transferred to the storage
reservoir to begin with. If the coffee level in the
reservoir falls below 1.2 litres, the WMF Cafemat 2
starts an automatic refill brewing of fresh coffee
(0.75 litres). Should the coffee level fall below
0.75 litres, coffee dispensing is disabled. No more
coffee will be dispensed until refill brewing of fresh
coffee has taken place.
Press to confirm your selection.
If you choose “Half Full” as the quantity pre-
selection, then instead of the empty storage reservoir
the display shows:

90
If coffee has already been brewed into the storage reservoir,
the display shows the current level in the reservoir. In this
example, the pre-selection is half full and the storage
reservoir contains 1.3 litres of coffee:
Note:
Up to 3.0 litres of the actual contents of the storage
can be displayed.
The quantity of coffee currently stored in the storage
reservoir is displayed in litres in every quantity pre-
selection stage (except for coffee machines in self-service
operation mode, see chapter 8.4.2 on page 105).
Full
3.0 litres are transferred to the storage reservoir to
begin with. If the coffee level in the storage reservoir
falls below 2.3 litres, the WMF Cafemat 2 starts an
automatic refill brewing of fresh coffee (0.75 litres).
Should the coffee level fall below 0.75 litres, coffee
dispensing is disabled.
No more coffee will be dispensed until refill brewing of
fresh coffee has taken place.
Press to confirm your selection.
6.6.2 Manual quantity control
Stand-by (zero litres)
This setting should be selected if you want to empty the
storage reservoir completely and no refill brewing is
required.
Coffee stored in the reservoir will continue to be
dispensed until the level reaches approx. 0.3 litres, at
which time dispensing will be disabled. The remaining
coffee can then be dispensed manually (see chapter 7.9
on page 120)
Press to confirm your selection.
If you choose “Stand-by (zero litres)” as the quantity
pre-selection, the display shows.

5

92
6.8 Coffee Dispensing by Fresh Brewing
(not possible on machines without fresh brewing option)
Caution!
There is a danger of scalding in the area of the
coffee spout 5and 16!
When the corresponding beverage key is pressed, a
brewing cycle begins, using the specified quantities of
ground coffee and brewing water.
On machines with an integral storage reservoir and the
fresh brewing option, a coffee beverage can be freshly
brewed without passing through the storage reservoir.
This can be useful if:
1. the storage reservoir has already been emptied but
coffee is still required.
2. a coffee beverage is required which has to be prepared
using a different type of ground coffee which is in the
ground coffee hopper.
If the ground coffee hoppers have been filled and the
machine is ready for operation, coffee beverages can be
dispensed by pressing a beverage key.
The display shows the following:
Only the beverage keys for beverages that can be dispensed
at the time are active. Otherwise, please refer to the
messages in your WMF coffee machine display.
Press the appropriate beverage key.
2. While brewing is taking place the name of the coffee
beverage selected and the progress of brewing are
indicated in the display by a cup filling up. Quantity
pre-selection is possible (see chapter 6.9, page 93).
The used coffee grounds are collected in the integral grouts
collector 15. All the beverage keys are now activated again
and the display shows that the machine is ready. The
machine is now ready for the next brewing cycle.
