I am not so worried about scum build-up, thats easily solved with vinegar. I am worried about limescale deposits on the heating elements and other parts of the machine. Thats why I am trying to source the watersoftener to mix with the powder. I am adding Borax and Washing Soda anyway.
If you have hard water to that degree, you might want to consider investing in an inline water softener for your plumbing. They have one that uses rock salt that is just great. There are other types too, if you're concerned about increased sodium intake (or you can drink bottled water).
Another advantage of a water softener is that the rest of your plumbing, not just your washing machine will last much longer without the lime scale. Water heaters last twice as long with soft water.
