I'm 1.5 minutes in and I already learned to purge cold water from the pipes before running the dishwasher. Assuming this is evidence based and true, I mean come on! Is it really so alarming to see someone deep dive hard and do the work to mass educate the public?
It seems like it would be trivial for the machine to pump water in, turn on the heating element, and wait until it reaches optimum temperature before beginning the cycle.
