This morning I was starting the dishwasher like I've done hundreds of times.  For my really heavily soiled loads, I choose the Auto > Sanitize > Extra Dry options and the time sets at 2:51.  This morning I did what I always do and noticed the time was set at 3:01.  


The difference was the "Add Rinse Aid" light had come on.  So I filled the Rinse Agent dispenser and the time went back down to 2:51.  I had no idea the machine would do this.  I guess it assumes if there is no Rinse Agent it will have to dry longer??  Anyone else notice this?

This feature has been around for years. The lack of rinse aid results in a hotter final rinse and/or extended drying.

Back in the 90s, that feature was called auto 3in1, as the dishwasher would "automatically adapt" to multi-purpose tablets that need no additional rinse aid in the dispenser.

I have the Bosch 300 series and did notice the same issue also how the time increases without rinse aid added. I have the machine a short time and like it and I do use rinse aid! The sanitize and extra dry are basically the same option they both heat the water to 162 degrees in the final rinse. My area I live in has soft water so I keep the rinse aid set at Low # 2, plus I live in a coop where the water is so hot I don't need to use the sanitize or extra dry. Everything comes out clean and bone dry! The walls of the DW are wet but I don't care about that as long as the dishes are dry. Only plastic things are at times damp. Over all I am very Happy with this DW!
