KDM-21
yes my family had a kds19 series and it heated the first and last rinse to 150 degrees before the water circulated! A lot of people didn't like the 19 series because it didn't have a drying heater and it was a longer cycle! the drying cycle was about 45 mins alone! and the fan went on and off! the drying results were only good if you used jet dry! By the 20 series they put back the drying heater but still did 150 degree heat in the 1st water fill and in your 21 series they cut back on water usage and had less water changes and I think the pre heat water was heated to 140 degrees! This process is what they called sure temp water heating! They kept this on later models for TOL models and mid to lower line had what was called sure clean water heating and would just heat the main wash to 140 degrees. All the InsinkErators used this sure clean water heating and main wash was automatically heated to 140 unless you selected energy saver wash! That to me was the simpler way!
anyway these older machines are far better than these newer machines!
