Congratulations on a beautiful machine, a true treasure. I remember the float chamber on our waterfall front Kenmore. Dad said there was no float in the machine, so I had the service man show it to him. That is not a timed fill. What the word and markings mean is that the machine would fill only in the area marked FILL. That would be from 20 minutes of wash to 11 minutes of wash. It also meant that if you wanted to use the delicate setting, you had to fill the tub and then advance the timer because there was no FILL that far into the wash portion of the cycle. If you wanted a lower water level for any load, you filled it to the level you wanted and then moved the timer to the area beyond FILL (10 minutes or less time) and let it wash along with less water. I really like that modern pointer for the timer, all asymmetrical with that big long pointer extending so far over the skirt. Have fun!
