Well I neglected to say that I gave this cycle 2 extra rinses on top of the rinses that it already does. I normally use the soil level setting one up from Normal, but this load of whites was very soiled so I thought that Heavy setting was called for. I also used a tad more Persil Pro White Pearls to really tackle the dirty socks and tea towels that I had in the load. The results were nothing short of stunning. Every stain came out. The Bright Whites cycle starts out with warm water and the water heater in the washer kicks on and does a "profile wash" where stains will release from fabrics at a certain temp and it moves on to add more heat so no stain is set...if that makes sense. It kinda cool that it does that.
So that theory of the hot wash water coming over into the rinse is not correct. In my opinion.
