With the Maytag dishwasher that I bought last year, I never use any of the cycle options, like Hi-Temp, or Sani wash. Or the Powerblast wash, whatever it is called. I only used Auto cycle, no heat dry, or even just the Normal cycle, no heat dry. It always takes around 1 hour and 15 minutes. Everything is always clean. I don't see the need to select any of these options, that lengthen the cycle time, and use more energy, when the regular Auto, or Normal cycle cleans just as well.
