Error messages and malfunctions
Basic procedure in case of error messages or malfunctions:
Switch coffee machine off and then on again after a few seconds. Repeat the process that caused the
malfunction. In many cases, this eliminates the malfunction and you can continue to use your coffee
machine.
If this is not successful:
Search in the error list for the error message and follow the instructions.
If this is not successful, or the error displayed is not listed, please call the WMF service hotline.
Some messages lead to blocking of individual functions. You will notice this by the fact that the
beverage button light goes out. The beverage buttons that are still illuminated can continue to be
served.
