Dishwasher

Question

I recently got a new dishwasher. It has either a quick wash setting that runs for one hour and I can add a heated dry-not sanitize- to that for another 34 minutes for a 1 hour and 34 min total. The other options are either auto or normal and they run for about 2 and a half hours with the option of sanitizing which will bring the total running time to 4 hours and 18 minutes for normal and 4 hours and 34 minutes for the auto setting. Which setting do you recommend I use to kosher the dishwasher? (Any news about the ronzoni gf pasta?!) Thanks so much Esther
