because when I went to their website recently and looked at the FL washers, I saw 3, the stainless model said "With Sanitize".....so I just now went back and I noticed they all say "with sanitize" and I never noticed that they all stated that the when I looked at them the other day. So NOW I'm thinking maybe they don't have heaters and that's just a built in cycle that sanitizes without a heater if you use Oxy or something like that? I got my hopes up (LOL)
