I am having some problems with the autosampler Dionex AS-DV.
When the needle goes down to take some sample, there is a moaning noise that prevents sampling and in most cases, there is a message "needle is jammed" and the status would be "interrupted."
When this happens, there are some other following issues:
1-sometimes the sample below the cap, passes through the cap and moves upwards (a crack in cap is observed)
2-the white filter in the caps is detached and floats in the sample.
I appreciate if anyone can help me with this issue.
