Vertical line across the print

Hey folks,
I cleaned the tank (underside) and the LPU Unit some weeks ago, but I get this horrible line across my model…
So do I need to replace the tank, or what are your first suggestions? The tank only printed around 1,5L so far, but I have these white dots on the underside from time to time (I guess it’s just dried resin. (Grey4)
