Part 5 Service
5/1 Start-up
5/1.1 General Information for Customer Start-up
In its factory setting, the coffee machine will automatically commence with customer
start-up after initial switch-on.
During the display-guided start-up program, the water system fills up. Various
prompts guide the user to set the water hardness and select whether a water filter will
be fitted. The date of the initial start-up is recorded in the statistics.
Once the start-up is completed, it can only be restarted if this has been enabled by the
authorized Service Center using the service program.
For any questions please contact the WMF Coffee Machines Service Department.
5/1.2 Information for Checking in a Service Center
The coffee machine automatically recognizes many electrical faults.
Error messages and operating states will be shown on the display. To enable identifi-
cation of leaks, it is recommended that the machine be cleaned and descaled.
The flow meter is designed for a maximum pressure of 1 bar.
Do not use compressed air to purge the water system.
™ Drain the boiler water system when needed (required whenever the coffee machine
will be exposed to a temperature of below 0° C, such as during shipping.)
™ With the service program in the testing environment, set the start-up flag:
-> This resets the initial commissioning date, and the coffee machine fills up. The
coffee machine statistics remain intact. Data-reset erases all statistics entries (see the
service program description.)
The last two points are required when the coffee machine is new, but has been and
initially started by the end user by running the customer start-up procedure.
5/1.3 Selection of Customer-Specific Settings
Copying Settings to Several Coffee Machines
Can be done only with the service program in the service center
Using the service program, machine data and beverage settings can be saved and
transferred to other coffee machines. Specific machine data, such as the counter, are
not transferred (see service program description.)
For any questions please contact the WMF Coffee Machines Service Department.
