    • 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.
