'H', 'W', 'C' Spelling Lesson
That's what my grandma's General Electric '2 Speed Automatic Washer' w/ the left-opening lid taught me, too...
'H/W', 'W/C', 'C/C' was what was above the Wash/Rinse Temperature knob... Speeds were 'Normal' and 'Gentle'... And loads were 'Small', 'Medium' and 'Large'...
