2998 PDA shutter assembly is not homing


This 2998 PDA is connected with a 2695 waters alliance.

How to resolve this issue?


  • Try right clicking on the box containing all the info labeled "2998 PDA Detector" and click on "Reset PDA". That should help!
  • I'm seeing the same issue with an Acquity PDA (seems to stick on Erbium filter). Flushing the flow cell w/ MeOH, resetting it, power cycling it, different lamp - all no help. I'm starting to think that either a board has gone bad, or a motor is not working.
