To this day, I can still hear in my head that 1/2 minute of the water entering the tub while it was still in pump out mode (courtesy of the drain solenoid still being open). It worked quite well. I think I also probably opened it up at the end of the main wash when I was old enough to realize what was going on. I'm a bit flustered right now. Yes, ours, bought sometime in 1960 or early 1961 (because it got moved to the new house September, 1961 to replace the O'Keefe & Merrit Dual Drench dishwasher that was part of the O'K&M kitchen). And in the library list, it was attributed as being a 1961 model. The 1964 version of this had the reversing motor for draining and dual level wash arms (like our 1968). The 1964 knob had removed with "wing" used to grasp and pull out the knob. It was a design that user turned the knob to the start segment and pushed in or pulled out the knob. The 1964 also had the same red idiot light on the panel as pictured here, where by ours and the one Paul is getting) had the dual pastel-colored emblem light on the panel. And those little red idiot "on" lights were the same even on our 1968 and friend's 1972 unit.
