SM-FL wash port problem

Have Acquity SM-FL.  After replacing the needle seal, I now see liquid coming out of the port behind the wash tube that looks like a screw.  What is the name and function of the 3 tubes in the wash station?  Am I only supposed to see liquid coming out of the wash tube?


  • Hi, JWright! Yes, there is supposed to be syringe solvent pouring over one of the wash towers when the wash syringes are pushing,   It pours over then goes to waste
