It will just sit and do nothing while it heats the water
Ralph, the 18 series didn't heat any water prior to the final sani-rinse just like the previous 15, 16, and 17 series. The 19 series Energy Saver IV was the firs KA to heat water several times during the cycle. Since I have to keep my eloectric water heater temp lower to save expense, an 18 with automatic water heating would be perfect--evgen more so if, as Tomturbomatic has stated NUMEROUIS times, if KA had kept the water circulating while it delayed to heat the water, it would have even better washability. Now to somewhat contradict what I've posted, the Soak & Scrub cycle did heat the water durinmg that cycle. Based upon the service manual or user guide, that cycle was about 40 minutes longerr than the 73 minute Normal cycle. The 18 seies finally lengthened the main wash phase severAL minutes more than the 9 minutes on the 16 and 17 series Superbas. Even as a teenasger I was concocting BobLoads that my mom's friends KAs didn't fully clean that my more modern dishwashers have managed to de beautifully. See what opportunities Hobart missed by not hiring me as a consultant back then. Just think of what even more of a K.A. dishwasher a KA would have been lol.
