A WMF error number needs the model beside it. This reference uses separate manuals for the 1300 S, 1500 S+, 9000 F VB and espresso NEXT. A matching number on a different machine is not enough to select a repair. Two other models have their own pages: the 1100 S grinder errors 9516 and 9517 and the 950 S water messages.
The page references count from the PDF cover. Scroll a wide table sideways on a small screen. The tables reproduce error descriptions; internal work is left to service.

1300 S: noise only during chocolate dispensing
The WMF 1300 S User Manual, April 2021, PDF page 114, puts this symptom in “Errors without error message.” It directs the operator to remove the mixer bowl and check whether the mixer wheel is correctly installed, using the mixer-cleaning instructions on PDF page 102. Follow that care chapter, not a grinder repair procedure. If the wheel or its fit needs repair, arrange service.

1500 S+ AutoClean: the Plug&Clean adapter will not fit
In the North America manual, PDF page 123, the symptom is an adapter that can no longer be inserted or locked. The operator check is whether the disc is seated properly in the Plug&Clean socket; the manual says that disc can rotate out of position. If it will not seat, stop and ask service to check it.
During cleaning or rapid rinsing, never pull out the adapter. PDF pages 91–92 warn of hot liquid and steam at the opening. Wait until cleaning or rapid rinsing has finished before checking the fit.

9000 F VB: the storage urn empties after a set time
PDF page 56 of the May 2019 WMF 9000 F VB User Manual describes the storage timer: once its configured time expires, the urn empties through the coffee-machine spout. The machine can also be configured to brew again afterward. Ask the responsible operator to check the site’s setting if that sequence is unexpected.
That documented behaviour does not establish a food-safety holding time for your operation. Follow your site’s food-handling requirements separately.

espresso NEXT: a portafilter remains locked
The April 2024 manual, PDF page 96, says this can happen if the portafilter is removed too soon. The brewing sieve is hot. The same passage warns that turning the mechanism in the wrong direction can damage hoses and the seal. Stop if the portafilter will not release normally and have a technician handle it; no piston or internal release procedure is given here.
If your display shows a different error, send its exact text with the model and software information available on the normal display. Independent WMF service can use that record to plan diagnosis. Contact the manufacturer’s warranty service first for a machine still under its warranty.
