In case of longer operating pauses please observe the instructions in the user manuals of WMF Coffee Machines, WMF add on units and WMF accessories!
If you take your coffee machine out of operation for a longer period of time we recommend the procedure described below. Please note that the corresponding preparation depends on the respective WMF device and its configuration.

- Disconnect the machine from power supply (pull mains plug)
- Close on-site water supply resp. empty water tank of tank machines (please note that the tank filter must be replaced when the machine is put back into operation, as it must not be dry)
- 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.
