I believe the man who suggested checking out the bleach dispenser was exactly right. I couldn't figure out why I rarely had problems with orange spots, and only on white clothes. But once I got some spots they were impossible to remove. I washed some work whites today. I don't usually don't use the bleach dispenser, I just dump the bleach in with the detergent prior to putting the clothes in.
While the washer was filling I pulled a soapy wet white washcloth out of the washer and wiped down the machine including squeezing water from the soapy wet cloth through the bleach dispenser just to clean up the machine. Now that I think about it, I only do this once in a while and only when I'm doing a bleach load. As I was taking the load from the washer I noticed quite a few of the dreaded orange spots on just one pair of white pants.
I found the post about checking the bleach dispenser. When I pulled the plastic dispenser from the machine, sure enough there was a bit of rust around the metal where the plastic dispenser fits. Now all I have to do is get some of the "Iron Out" as suggested for rust stains. Whoo Hoo. Thanks. ... View related article.
