STRATEGY
- Inspect the Instrument Method for high-pressure limit setting. - WKB48643
- Check that the flow rate hasn't been set too high. - WKB241566
- Reset pump head transducer. - WKB47479
- Remove the column to see if pressure drops. - WKB76470
- Remove Active Preheater (APH) to see if pressure drops. - WKB60838
- Inspect for blockage at the needle, needle seat, or tubing. - WKB9936
- Possible faulty transducer. - WKB2495
