Agilent 1260 infinity ii high back pressure

We are having a high back pressures issue with Agilent 1260 infinity ii, and the clog has been identified to be somewhere in the column compartment area between the heat exchanger inlet and the column inlet. However, we are stuck because we do not have access to the related capillaries due to the design of the vialsampler as shown in the picture.. anyone else had high pressure issues in that area? Thank you

  • Try moving to the 2nd channel which looks like it's not being used.   

    1-Move the red capillary from port 5 to the right I see a white nut- move that over

    2- where you have the column inlet circled remove the white nut there and then do you have flow to that point?
