Dionex P680 HPLC Pump would not run.
When I set up prime or flow rate, the pump stops.
It shows: Drive Current too Larse. Camshaft 157 degree or
Excessive drive current. Camshaft 160 degree
Then it stop run.

i have let it rest one day, then it also has the problem when i try to use it.

These error messages typically indicate a blockage in one or more capillaries of the pump fluidics. Inspect them for signs of blockage and replace them if necessary. If you should require additional support, please contact your local legacy Dionex support.
