Under normal use, the timer dial did not have to be touched. The dishwasher was started either by pushing down the START switch beside the door of the machine from the first model through the 12 series or pushing a cycle button (KDI-14, KDS-14) & 15s or flipping the start switch under the door handle (KDC-14). The pointer was at the top of the dial so it was always easy to see the stage of the cycle. Even the first portable KD2P had the start switch under the door handle so that even though the timer was way down on the front, you did not have to do anything with it to start the machine. The START switch that had to be pressed down an inch or so, actually had a mechanical link to the timer that moved the timer 1 increment which turned on the power to the timer which started the dishwasher. The 14 series did it through the door latch and by the 15s, it was done electrically. Pushing a button to start the machine was a far more foolproof method of starting than having people turn the dial like in the non-pushbutton models from the 16 series forward. People sometimes would turn them just enough past the start point that the cycle would miss the first fill and when the water heating part of the cycle started in the 19s and newer, it fried the vinyl on the bottom rack and burned any food soil that might have landed on or just above the element. Then customers would call that their dw was burning up.
