You don't have hard water in the house if you have a water softener unless the water softener isn't working, is your softener using salt, do you find little tiny plastic looking beads in your sinks? Either of which would be an indication of the softener not actually working. I live in the desert, but have lived all over the country, no body has water as hard as we have in the desert, and I mean nobody. Very few people use water softeners and don't have this problem. The porcelain paint will not rust unless its being chipped off to expose the metal surface under the paint. Hard water will not eat away the porcelain.
This problem happens from items in the washer banging into the drum and chipping the porcelain paint off. Metal buckles or fasteners on your clothes, or even those plastic fabric softener or soap dispenser "balls" have been known to cause this problem. The plastic balls have been known to bang around so bad during the spin cycle that they will cause the paint to chip. If you do use these stop, if you don't use these take a closer look at the clothes you are putting into it for pieces of them capable of chipping the paint. This is whats causing your problem, its been a known issue for years.
