You and I have been through this before, and I don't know how to prove it any better than sourcing the offical Food and Drug Administration web site yet AGAIN:
FDA
"Hot water for handwashing shall be of a temperature of at least 110°F. Hot water for mechanical dishwashing must be 150°F-165°F for washing and 165°F-180°F for sanitizing. The temperature of the wash solution in spray-type warewashers that use chemicals to sanitize may not be less than 120°F. The water temperature for manual hot water sanitization must be at least 171°F."
I'm going to edit my original post that included the temperature, because I wrongly said it was 160 degrees, when sanitizing is actually 165+ degrees.
However, you are sorely wrong on your statement about home dishwashers not being able to sanitize. I have a low end Kenmore model that has a special sanitizing cycle. Based on your information (which you've provided no accurate source) should I go ahead and prepare the lawsuit against Sears for false advertising?
