My allergen default is 1:42 and that's heavy soil. Light soil drops it to 1:34. Steam for stains raises default to 2:05. Sanitize on the following cycles yield: Allergen 2:25, Heavy Duty 2:20 and Whitest Whites 2:43. Adding Steam for Stains raises all those to 2:43, 2:25, and 2:56 respectively. I will tell you with a very heavy load of towels on Allergen, I've seen the machine add up to 28 minutes to the wash time to make sure it has plenty of time to head to its target temps. Alex, mine is a WFW97HEXW0. The fill flue is about at the 10 O'clock location inside the machine. Tis is a rubber nozzle type of things on the gasket (with a hole) at about 11:00 o'clock. I'm assuming that's for steam. I've never used the cartridge so I don't know if that's what that's really for. Yikes Eugene. If my mother was there she'd say, that's what you get for opening the machine during its cycle. You're supposed to leave it alone lol.
