Joe,
I noticed that your KD-10 also has a fan blower for the dry portion of the cycle.
It's sad that it isn't a common feature on all DW's. If would make things dry so much easier and eliminate condensation left over after that part of the cycle finishes especially on plastics.
And WOW! 35 minutes for a complete cycle. Compared to today's DW you could almost do three loads of dishes in yours compared to the time that todays DW's would do one.
Running times may vary, but considering the differing motor sizes between then and now, it is (probably) a moot point. Not sure of the wattages between machines, so I can't say for sure. The bigger differences would come from insulation and actual water usage today.
Alright. So now I think Im going to keep my eyes open for a KD for my 1956 MCM home renovation. From what Ive gathered here I think it would do a better job than my 56 GE? What was the last year for the KD? And how many models/revisions where there in the line?
