Steps to follow:
Warning: Beware the sharp needle tip: Avoid touching it so as not to get pierced.
Flush the loop by closing the purge valve. Remember to collect the solvent flowing out the loop end. Afterwards, reconnect the loop capillary to the needle assembly and move up the needle sufficiently (by clicking Up). Flush through both loop and needle, collecting the flow coming out of the needle tip (be cautious not to pierce yourself). Next, click End to reposition the safety flap around the needle. Replace the front cover of the autosampler and reset the module. Go on with step 5.
If this does not solve your issue, then please contact your local Agilent Support representative for more help.
