Regarding:
Dionex ICS-3000 system
DP dual pump compartment

Pump shuts down with errors of:
Drive current too large
Excessive drive current

This after running variously for 1-6 hours.

Prior to errors, system running normally, about 1550 psi at about 0.25 mL/min

Per Dionex troubleshooting guide, replaced all tubing. Problem persisted. Rebuilt dual pump including seals and check valves. Problem persists.

Ideas??
Hi opsuwaterlab,

This error usuallly requires the pump mechanism to be replaced. Please contact your local service team if you have not done so already.
Best regards,
