I’m not sure any washer fills the tub anymore. Might be a water conservation thing. I can add more water to my Speed Queen manually but I must stand there to hold the button. It doesn’t take long, really. Speaking of that, my washer filled so slowly then I discovered the water inlet wasn’t turned on all the way and had been that way for 4-5 years. DIL’s washer has a nice big tub but mine is actually small compared to hers.
