Is the first button intended as "Part(ial) Cycle?" Or is it literally "Part Cycle" ... as automobile parts, farm machinery parts, etc. .... a really new Concept!
Why would a button be needed to differentiate a Partial Cycle? The timer can be turned to any desired starting position, no buttons for Heavy vs. Normal or Rinse'n Dry or Plate Warm.
about 1968 I'd say. Wonder if D&M had the tilty door latch as an option for the OEM manufacturer to choose. Would be kind of fun to see the "catalogue" of options for the product manager at Kelvinsonchef to choose from.
Yes, I agree about the "Part Cycle" or "Partial Cycle" being a "Rinse and Hold", if it doesn't automatically shorten the cycle or speed up the timer dial...
Rinse Hold vs. Rinse'n Dry has a difference of no drying. It'd be more logical for that purpose to label the button Rinse Hold, Heat Off, No Dry, or some such.
Rinse Full
Hold Cycle
