DIONEX ED40 no Conductivity Reading

[CLSgroup]

Right now I am not getting any reading for Conductivity. I have turned it on using both the remote and local option but still nothing. I went to the diagnostics and went to calibrate and simply hit cal. the conductivity came back for 2 min then went back to 0. Last weekend we had an issue with out auto sampler where the arm jammed, rather than shutting off the system was stuck at 1.20 and completely ran out of eluent so the system was running dry for about a day. I was able to prime the pumps and everything seemed to be working fine but now I am having this conductivity issue. Do you think I have a defective cell? Any troubleshooting tips for the issue? If the cell is defective could it be a result of the system running dry?

The conductivity cell is usually pretty tough. I wouldn't expect drying out to effect this.
