Replacing characters w/ new actors

Why did they replace the original actresses who played Housekeeper/Mrs. Norseng and Ileanna? I can assume due to titles that perhaps they can say that the family had different housekeepers (although they made sure to have the actresses look alike). Same w/ Ileanna, read that some people didn't even realize it was a different actress.

But wondering if they did try to have the original actresses but maybe there was a conflict ~ does anyone have any details?
