Depending on machine type and configuration, please remove the removable parts such as, for example, milk foamer, milk hoses, steam nozzle, powder mixer, brewer, grounds container, bean/ground coffee/topping/choc hoppers according to instructions in user manual, clean them and allow them to dry outside the machine. These parts can then be reinstalled. Please note: On some machines individual components cannot be removed! Observe user manual!

      Advice concerning water filter in combination with fixed water supply

      • After longer operating pauses, please rinse the filter system with at least 20 liters of water.
      • If the filter system has been out of operation for more than 4 weeks, a new filter cartridge must be inserted.


      Advice concerning water filter in combination with tank machines

      • In case of tank machines: Insert a new cartridge according to the instructions in the user manual.


    4. Check whether all parts after having been removed and cleaned are reinstalled correctly
    5. Then carry out two complete machine cleaning cycles
    6. Afterwards, the coffee machine can be put back into operation.



    Recommendation for machine care in case of longer machine downtime (fixed water supply)


    The filter change (advice concerning water filter – see above) can be avoided if you carry out the following tasks every two days:

    • Connect machine to power supply
    • Open water supply
    • Switch on machine and dispense hot water at least 5 times
    • Carry out system cleaning without cleaning tablet
    • Switch off machine
    • Disconnect machine from power supply (unplug)
    • Close water supply


    WMF recommends not to switch on the coffee machine only on the day of re-opening. Please test the function beforehand in order to contact your technician if required.


    Additional information:
    These instructions/advice reduce the probability of damage caused by a longer machine downtime. However, damage cannot be excluded. If damage occurs due to the downtime, its repair is not covered free of charge in the full maintenance contract.
