2 General description
The WMF CAFEMAT is an expert in filter coffee.
In terms of flexibility, its novel system establishes new
standards. Single cups, pots and multi-brews allow
optimum adjustment for varying requirements. Each
quantity is freshly brewed at the push of a button. A hot
plate 16 is provided if coffee has to be stored for a larger
demand or you may brew directly into a coffee urn
using multi-brew arm 10.
The brewing water is heated in a boiler system. Not only
filter coffee but also hot water may be dispensed.
The dry disposal of coffee grouts allows for flexible
locations. Drainage is not necessarily required, although
each unit is equipped with a drain.

3Warnings
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 40.
For your own safety,
please observe the
following instructions
Connection of the machine 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 service technicians or
authorized persons.
Only original parts should be used.
In no circumstances should any alteration be made to
the built-in safety devices.
Caution! Risk of scalding!
Keep away from the hot water dispenser 14 and the
coffee dispensing spouts 9 and 10 to avoid being scalded.
Caution! Risk of scorching!
Do not touch the hotplate 16 or Brewer 20 when the
machine is switched on.
Caution! Risk of crushing!
Never reach into the coffee hopper 1 or brewer 20 when
the machine is switched on.
Caution! Health hazard!
When handling the cleaner, always follow the safety
instructions on the pack. The cleaner is corrosive and
can hurt. Because cleaning fluid flows out of the coffee
dispensing spouts 9 and 10 during cleaning, place a
collection tank below the machine to collect the cleaning
fluid safely (for machines without drain connections
only). Do not use a cup or breaker, for the cleaning fluid,
it is impalatable.

4 Safety instructions
General notes
1. Always ensure that the water tap is turned off when the machine is no longer in use and that the
master switch outside the machine is switched off and /or the machine unplugged from the mains
supply.
2. The built-in type-tested safety mechanism prevent any impermissible increase in pressure and
temperature in the water boiler. The machine must be switched off immediately if the relief valve
is tripped. 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. The machine must never be hosed down with a jet of water or steam. The surface may be cleaned
with a damp cloth or one of the products from the range of WMF care products.
5. The unit must stand safe at a ground level, on a horizontal and stable base.
Machine shutdown - holidays
1. The machine should be cleaned and the coffee grouts container emptied before it is taken out of
service for a longer period of time. It is essential that the machine be drained in order to prevent
frost damage if there is any risk of freezing temperatures. The WMF customer department should
be contacted in good time in such cases.
2. After a shutdown of several weeks, we recommend running the automatic cleaning cycle at least
twice before start-up of the unit.
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 operator of such equipment is responsible for due maintenance and verification of the safety
mechanism.
The machine complies with all the relevant regulations.
The operator is obliged to ensure that electrical plant and equipment is tested to establish that it is in
safe working order.
Page 9
41
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 9° (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.

7.5 WMF CAFEMAT with personnel accounting/
vending unit
The WMF CAFEMAT can be fitted with a vending unit,
e.g. a coin checker or coin changer, to enable the WMF
CAFEMAT to be operated in self-service mode.
If the WMF CAFEMAT is connected to a CMT, every
cup/serving dispensed is recorded. The waiter’s lock for
this accounting mode is in the CMT. A printer can be
connected to allow the daily totals for each waiter to be
printed out (see Fig. 8).
Figure 8
Other special features:
- Instead of the ON/OFF switch there is a key switch 11.
- The ground coffee hoppers have an `empty` warning
and are lockable. The `empty` warning for coffee
hopper 1 is indicated by the “cup” button flashing
slowly. The `empty` warning for hopper 2 is shown by
the “pot” button flashing slowly.
- On the WMF CAFEMAT with vending unit, the
brewing arm is always on the left. The reason is that a
vending unit or CMT is always fitted at the right for
ease of operation.
Figure 9
- Every machine with a brewing arm has a jug tray 24
(Fig. 6; not fitted on basic models) with a locking
mechanism for the brewing arm.
- The customer service engineer can allocate the “pot”
button to the 2
nd
type of coffee, so that in self-service
mode, a normal coffee can be made by pressing the
“cup” button and a mild coffee by pressing the “pot”
button. There is no need to press a “SPECIAL” button
first.
- Every WMF CAFEMAT with a personnel
accounting/vending unit can be used to check the
number of cups or pots (with coin checkers, only the
number of pots or cups can be output). Quantities can
be output free of charge by means of a release switch
25 (Fig. 9). It is not possible to check half and full jugs.

7.5.1 One-price coin checker
The WMF CAFEMAT can be fitted with a coin checker
(Fig. 10) for self-service operation. The coin checker is
switched on by a switch 30 inside the coin box. Coins may
be inserted when the “ON” lamp 29 is lit. The “ON”
display on the coin checker is illuminated when the checker
is switched on and there is sufficient ground coffee. If the
coin checker is switched off, products can be dispensed
free of charge.
Coins or tokens inserted into the coin checker (coin slot 26)
are collected in the lockable coin box 31.
The coin checker can be set to a single selling price. If the
coin checker malfunctions, press the “Coin return” button
28. The cash or tokens can then be removed from the coin
return chute 27. If products cannot be dispensed, the coin
slot is blocked and the “ON” indicator 29 goes out.
Figure 10
7.5.2 Coin changer (4 prices)
See the separate instructions for operation and setting of
the coin changer. Coins or tokens inserted into the coin
changer are collected in the lockable coin box.
The coin changer can be set to different selling prices. If
the coin changer malfunctions, press the “Coin return”
button. The cash or tokens can then be removed from the
coin return chute. Change is also given via the coin return

8 Care of the machine
8.1 Emptying of grouts and water container
The WMF CAFEMAT employs a ground coffee dry
disposal device, i.e. coffee grouts will be collected after the
brew cycle into grouts container 22 inside the unit. At the
same time, expansion water from the boiler will be
collected in water container 21 (see Fig. 11).
If grouts container 22 is full, water container 21 should be
emptied at the same time.
If grouts container 22 is full, the unit will signal as follows:
a) After selecting of a brew cycle, 3 short buzzing sounds
will be audible indicating that
Æthe grouts container is almost full
b) An intermittent buzzer will sound, hot water button 13
will flash and the dispenser will be blocked, this
indicating that
Æ the grouts container is full
The disposal process is as follows:
1. Open doors 7 and 8.
2. Slightly lift up the water container 21 and draw it out to
the front.
3. Push grouts container 22 to the left, lift slightly and
also remove towards the front. Empty out coffee grouts.
4. Reassemble in reverse order, remembering to throw the
locking lever 18 before closing the door.

Cleaning fluid emerges from the coffee dispensing
spouts 9 and 10 during the cleaning process. This
fluid must be collected in a suitable vessel if a fixed
water drain is not installed. Do not use a cup or
beaker, for the cleaning fluid it is impalatable.
Health hazard!
9. An acoustic signal sounds intermittently at the end of
the cleaning program and the “Hot water” button 13
flashes slowly. The water container 21 and coffee
grouts container 22 must now be emptied (see page 50,
0 Care of the machine).
10. The machine is switched off via the “ON/OFF” switch
11 after being cleaned.
11. If the machine is not connected to a drain, the drip pan
can be removed for cleaning. Simply draw the drip pan
out to the front (see Fig. 14).
Figure 14
Caution!
Note: Hot plate 16 may still be warm! Risk of
burns! The “Hot plate” switch 12 must be switched

For units in continuous operation, cleaning must be
carried out within the next 24 hours. Otherwise coffee
brewing will be blocked.
For units that are switched off after a operating time of
26 hours, a cleaning cycle must be run upon switching
on the machine. Only after that cleaning program,
brewing are possible.
Cleaning warning:
on switching on, the “cup” button 6 and “pot” button 5 will
flash quickly and continuously.
The cleaning display 23 on the button panel will also flash.

10.2 Operation
Jet brewing operates by keeping the coffee concentration
relatively constant by means of an admixing valve. This
allows the brewing time to be reduced by about 30%
compared to normal brewing. This saving of time makes
peak demand occurs (for example, at conferences) which
cannot be met with the standard WMF CAFEMAT.
10.3 Special features
- The WMF CAFEMAT JET is fitted with a large brewer
to allow 1.6 litres to be brewed at a time.
- Cup and pot brewing are not possible.
- A short spout is fitted to allow jugs to be filled.
- The quantity of ground coffee can be set separately for
each product button.
- The ground coffee hoppers have an `empty` warning.
The `empty` warning for coffee hopper 1 is indicated
by the 1/2 jug button flashing slowly. The `empty`
warning for hopper 2 is shown by the 1/1 jug button
flashing slowly.
After refilling with ground coffee, confirm by pressing
the button which is flashing.

- The minimum brewing quantity is 0.8 litres (0.5 litres).
- The maximum brewing is 1.6 litres (1.0 litres).
- If the brewing arm is pulled out, the following
quantities may be selected from the quantity program:

Other options:
1. This allows jet brewing only. There is a choice of two
types of coffee. The chosen button gives direct access
to the ground coffee hopper, with no need to press the
“SPECIAL” button first.
2. This allows jet brewing only, but with only one type of
coffee. Only two buttons are in use (the others are
blanked) and the ground coffee is taken from the two
hoppers alternately.
These options can be set by our WMF customer service
engineer.

12 Warranty claims
WMF shall give a warranty for legitimate defects as to quality as follows:
Any products delivered or any services rendered showing a defect as to quality within the period of
limitation shall be, at WMF’s reasonable discretion, repaired or rendered again, if the cause of the
defect as to quality had already been present when the risk was passed.
Claims for defects as to quality are subject to a limitation period of 12 months. This period shall
start with the day when the risk is passed. The above period shall not apply in case there are longer
periods required by the German Civil Code (BGB), e.g. pursuant to § 479 Sec. 1 BGB (right of
recourse of the contractor), 438 Sec. 1 No. 2 BGB (buildings and things for buildings) and § 634a
BGB (defects of construction).
The warranty period is extended to cover a period of 24 months after the risk was passed, if the
buyer, at the time of concluding the sales contract, also enters into a service agreement for a regular
maintenance of the percolator purchased. The extension of the warranty period is only effective, if
the service agreement concluded has a minimum term of two years.
If putting the machine into operation is delayed for longer than four weeks due to reasons that are
beyond the control of WMF, the warranty period shall begin four weeks after the machine being
delivered to the customer.
The buyer shall immediately give written notice of defects as to quality to WMF. Replaced parts
shall pass into the ownership of WMF.
At first WMF shall always be given the opportunity for a subsequent performance within a
reasonable period. The buyer shall make available the rejected object to WMF.
We do not give a warranty:
-
for any components that are subject to a normal wear and tear. This includes but is not limited to
gaskets and washers, ribbons, and proportioning devices;
-
for defects caused by atmospheric influences, deposit of boiler scale, chemical, physical, electro-
chemical or electrical influences, unless these defects are attributed to a fault of WMF;
-
if a water filter is dispensed with, although the on-site water regime requires the use of a water
filter, and this results in defects. It is pointed out to the customer in the respective
acknowledgement of order, whether the use of a water filter is required;
-
for defects resulting from the failure to comply with the instructions relating to the handling,
maintenance and attendance of the device (e.g. operating and maintenance instructions of WMF
laid down in the operating manual of the respective percolator type);
-
for defects resulting from the inappropriate or improper use, from the failure to use WMF
genuine spare parts or from the faulty installation by the buyer or a third party, or from a faulty
or negligent handling; and for consequences from modifications or repair works that were made
improperly and without our consent by the buyer or a third party.
Claims for damages by the buyer, irrespective of their legal grounds, particularly on account of
violations of the contractual obligation and on account of tortious acts, shall be excluded.
The above exclusion shall not apply in so far as there is a mandatory liability, e.g. in case of giving
warranties as to quality or durability, pursuant to the German Product Liability Act, in cases of
willful acts, of gross negligence, of fatal injuries, of bodily injuries or injuries to health, or in case of
any violation of substantive obligations from this contract. A reversal of the burden of proof to the
disadvantage of the buyer is not implied by the above regulations.
