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 contact your local WMF Reseller.
Some messages lead to blocking of individual functions. You will notice this by the fact that the

served.
