Early WCI Skinny-Mini
Yes the GM Frigidaire versions of these machines never had a knob for water-level, they had timed fill with their solid tub design.
You can see this SM still had the GM fire hazard designed heater assembly in the dryer, WCI had to change this bad design before GE would buy this product to sell under the GE name, this is also when the plastic washer door and washer lid disappeared, also to reduce the risk of fires spreading to the homes surroundings.
