If water flows to the sewage when the BADU Control Unit valve is in the FILTER position, it could be due to contamination from small parts or sand, or a loose/worn valve seal. Remove the valve lid to identify and clean the valve, addressing any overload issues. Another cause may be that the cam disc is not set correctly, in this case you should send the complete upper part to the manufacturer. Also, ensure the valve cover with actuating drive wasn't mounted twisted by 180°. If so, undo the screws, turn the whole unit 180°, and tighten the screws, making sure the angular cams of the valve and valve cover match.
