"You really want Patty because she has the constant rinse, right? "
EXACTLY. My Hot water for the kitchen is about 20' off the boiler. So Water in the Kitchen is about a serious 160 F all the time.
And Yes, the Constant Rinse makes all the difference after the Spinner Died. That "Slit" on the Upper Wash Arm feed is Crap.
When I bought my KDS-19 I thought I would have the Constant Rinse. I was so bummed out when the top of the tank was bare.
That "Spritzer" makes a huge difference. I have a KDS-20. Great Machine... but I love that None Stop Motor through the whole cycle plus the 9 water changes.
The KDS-20 is OK, but I hate that silence when it's filling. When the 15 series came out I was "Stoned" on the sound of that motor running through the complete cycle never missing a beat until Dry Time
