Are these signs of an incipient flapper motor failure? Or is there some maintenance I can do to rectify the situation?

What you describe is how flapper-motor failures have presented themselves to me when they've occurred. Replacement of that motor is not a difficult repair. I've only had a couple of those failures in almost 30 years of doing this stuff.

Same here; not a difficult in-house repair. Once I had to rivet a flapper back onto its support. I think I did about 2 of these electric motor assemblies on 6890s, and at least one on the 5890s, they are different.
I stocked a spare electric motor for each series, were different.
In my last few years, my pointy-haired boss likely would've called in Agilent Service, as he'd be terrified that this would compromise cGMP validations because I didn't have a certificate on file stating that I "was qualified". So good to be retired and away from him. In my career, there were a few things that I showed service engineers what to do !!! I was still allowed to "point".
