3 Warnings
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 11 and coffee 6 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- 11 and coffee spout 6 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 6 while 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 6 while 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 hopper 1 or the
granulate cleaner reservoir 3 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.

4 Safety instructions
1 Always 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.
81
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
• There are always operating dangers associated with every technical device, particularly from
large fully automatic machines which are operating unobserved.
• We 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.
• If 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.
• Maintenance 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.
