Great reply, except you haven’t read any plumbing codes it appears OR any publications by any recognized health departments.
The actual recommended MINIMUM temperature for a dishwasher is 140-160 degrees WASH and 180 degrees for final rinse UNLESS you use chemicals for disinfection in lieu of the 180 degree temperature (commercial applications) BUT residential still require 140 MIN
Even today there is a major concern among health officials AND LMP’s about the lower temperature H/W heaters out there (125 deg Max)
Did you honestly expect cold water to kill ANY bacteria in a breading place (incubator) like a D/W?
