Quat Pump "Leak, Drive off, out valve block position" and Vial Sampler "Valve command failed, transport command failed" Error Messages

I am using an Agilent 1260
Infinity II Prime LC comprised of: Quat Pump (G7104C),
Sampler(G7129C),Column Oven (G7130A) and DAD
The instrument is displaying an error message for the Quat.Pump – Leak, Drive off, out valve block position
and the Vial sampler is displaying Valve command failed, transport command failed.

I am unable to clear the error messages and get the instrument running.


Please could you advise on how to rectify these errors and any troubleshooting manuals that describe the potential error messages and remedies.

Kind Regards

  • Thanks for your reply. I have searched the manuals for description and meaning of The error messages like I posted but couldn't locate any reference to them. A service engineer has visited and rectified the problem which was caused by the installation of the outlet tubing. We do not have LabAdvisor installed, do you think this going to cause any difficulties doing maintenance or troubleshooting?
