What Water Filter Symbol flashing
actually means.
A flashing water filter symbol is a reminder that the filter is old and needs replacing. It can keep flashing after you fit a new filter if the filter is not seated all the way, or if the new filter has not been activated on the panel. Nothing has broken.

Before you book,
in this order.
Each step comes from Thermador's own guidance for Water Filter Symbol flashing on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Replace the filter if it is due.
If you just replaced it, check that it is turned all the way in and the lines on the cap line up with the lines on the compartment.
On some models, hold LIGHT / FILTER or SUPER COOL together with ICE for 3 seconds to activate the new filter.
Check your owner's manual for the button combination on your model.
Cleared?
Nothing needed repairing. If the refrigerator does not settle back to temperature, that is a separate problem.
What not to do
It is not a cooling or water valve problem. The symbol is only asking for a new filter, or for a new one to be activated.
