autoreference error 25089

Question

Hi all, 
 
 We encounter a problem after doing a PM of the G7167A MLS, when doing auto referencing after changing needle seat and seals, it gives and unknown module error 25089. As the MLS require realignment, it won&rsquo;t let the needle be in service mode. I use lab advisor try to move the needle in the &lsquo;Instrument control&rsquo; page, it gives another error 25146 means the value of the needle is missing, I cleared the auto reference value in lab advisor, restarted with no luck. I tried a cold start also with no luck, and I reinstalled the same firmware and it still no luck. 
 I unclick the needle take the needle out and unscrew and screw it back the wash port in case the wash port isn't aligned. but now I couldn't put the needle back. I restart the MLS and it reinitialize ok as usual but ask for realignment otherwise it always in not ready mode. Once do autoreferencing in instant pilot controller and the same unknow module error 25089 occur. 
 
 Any ideas? 
 
 thanks in Advance

Hi CandyCheong, if you are not trained by Agilent on repairing LC instruments I do not recommend you open the module. The errors you experience are due to the washport. If the module is not ready you still can update the FW and Lab Advisor, right? As a plan B, you can buy and install a new wash port.

Hi Nadjan, I have some good news . I ordered a drain management kit G4267-68708. I replace the only washport in G7167A, and it successfully completed the autoreferencing. You were right, it is all due to washport, I did not change the whole drain kit, I only took the old washport out an put a new one from the kit and replace it. 
 Now the autoreference is completed and it allows me to move the arms and in service mode. Everything back to nornal
