Congratulations on the purchase of your
WMF Coffee Machine
You will be impressed by technical design, durability,
economy of use and first and foremost the quality of the
coffee.
The WMF presto coffee machine is a
fully automatic single-cup machine for espresso,
café crème, cappuccino, milk coffee,
foamed milk and hot water. Optionally also hot chocolate
beverage and steam dispensing is possible.
Each beverage is freshly brewed at the press of a button
which guarantees high quality beverage.
Operator control of the machine is possible via a graphic
touch-pad display.
Keep these instructions near the coffee machine so that
you and your operating staff have the right information
handy and can take the correct action in the event of any
technical problems.
The coffee machine is designed to prepare up to 15,000
coffees and 6,000 chocolate beverages a year. After
every 10,000 brews, customer check-up by the user
is necessary and a full service is required after every
30,000 servings.
Please be sure to follow the instructions in the Software
- Settings - Water Hardness and Range Chapter and to
make the necessary settings.
In the event of failure to comply
with Servicing Information
(see Maintenance chapter) no
liability is accepted for any
resultant damage.
Similarly in that event all
guarantee/warranty obligations
cease to apply.
