   Not really confusing the issues. I was pointing out that a modern   
   machine doesn't need to do a boil wash to remove certain contaminants   
   from clothes and that the temperature of the water possibly plays a   
   lesser part in the total washing process.   
      
      
   Irrespective of the final temperature of the water and/or the selected   
   program the wash will start with a cold wash with detergent to try and   
   remove common stains that may be cooked in if hotter water is first   
   used. With this initial cold wash the machine has enough water to   
   complete the wash. It doesn't discard this water or detergent for the   
   rest of the wash - it just heats the water, if required. There is no   
   point at which a hot feed would be used on a modern machine.

   Especially as modern machines are also designed to use a lot less water   
   than their counter parts of yesteryear. The last machine I've owned that   
   had a (working)  hot feed was 30 years ago!
