..after several attempts to drain, I gave in an replaced the filter. This corrected the issue.

Worst case, you have contamination in the water-in-fuel sensor.
I haven't gone this route, but here's what I could find....

Note the orientation of the water-in-fuel sensor locating guides.

NOTE: Use care when removing the water-in-fuel sensor. If the sensor is damaged during removal, the fuel conditioning module cover must be removed and the module cleaned to remove any pieces of the damaged sensor.

Using an appropriate tool, turn the water-in-fuel sensor at least 45 degrees counterclockwise.
Pull the water-in-fuel sensor straight out of the fuel conditioning module.
Inspect the water-in-fuel sensor for damage. Make sure that there are no pieces broken off of the sensor.

I've read of users finding crud in the port that the sensor is plugged into. Perhaps you'll find something there, but I'd appoach the filter change as a 1st step.

Arm full of diesel awaits you....
