Steve and John, that water level theory matches mine exactly, and yes, I thought about how a larger load would cause the water to drop back down more slowly. I checked the float after the tub had filled and it can come up quite a bit further before I hear the click.
The fill is timed. It's two minutes long. When the TT was installed, we took the inlet from the Motley Maytag it replaced because the one on the TT leaked. Nate cleaned it up as best he could before installing it, because it had quite a bit of rusty crud caked up in it.
The pipes in this house are 80+ years old, and the ones leading to the kitchen sink are definitely the most used, and pressure there is less than ideal. I suspect the inlet valve is OK and it's just a matter of the pipes not being able to deliver enough water within the two minute time frame. My guess is that with adequate pressure, the tub would fill enough to trigger the float within the two minute time allotted.
