a lot of the TLers fool you with a WARM spray, leaving the false impression of a WARM full fill deep rinse....
outside of us, no one probably checks, and as long as the clothes come out warm, no one is the wiser.....this is more along the lines of an Energy Saver...
for my installation, with a Whirlpool, after the first fill with warm, the pipes cooled down, by the time it ran a warm spray, and the hot water got to the machine, the spray was over...you can't win!
