What to do if Parker SciLog FilterTec Plus pump head turns without tubing, but not with tubing?

If the pump head turns ok with no tubing installed, won’t turn when you put tubing in, and you don’t get a “Check Pump Head” error, the coupler is likely loose or broken. Contact Parker for tech support, or to arrange for service and an RGA#.
