Replace the filter if it is due. ### Why is my Thermador water filter symbol still flashing after I put in a new filter? Usually the filter is not turned all the way in, or it has not been activated on the panel. Check that the lines on the cap match the lines on the compartment. On some models you also hold LIGHT / FILTER or SUPER COOL together with ICE for 3 seconds. ### Does a flashing filter symbol on a Thermador mean something is wrong with the water valve? No, the symbol only asks for a filter change or for a new filter to be activated. Cooling and the water valve are not part of this message. The owner's manual lists the exact button combination for your model. --- **[Read on the site: Thermador refrigerator showing Water Filter Symbol flashing](https://refrigeratorrepair.center/error-codes/thermador-water-filter-symbol-flashing/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
