I have an old White Westinghouse "Heavy Duty - Large Capacity" washer that has a drawing of it's electrical setup with the number D148187 and 27" Washer as a sort of title - found inside the main housing. The model number label has gotten worn off it's back and there is no sign of Model Number anywhere on the "dashboard". The knobs are very simple - Left to Right, Water Level (Hi,Med,Low) , Timer/Mode select, Reg, Heavy Duty, PremPress,Delicate, ect. Can you give a Manufacture date range ?
