Frontaload:
There is no way to weigh-to-save with a side swing door, but you are right that it is an adjustable water level selector.
The main disadvantage with these machines is that like with the first Bendix machines, the water sprays into the top of the outer tub and onto the outside of the rotating cylinder, not into the cylinder and directly onto the tumbling load like with the full-size WH washers so the first flush rinse is not as effective at actually flushing water through the load.
