I love my LG front loader, I've washed several things that were "dry clean" only in the hand wash cycle, they've come out just fine. It uses very little water and is extremely efficient. I read about the other person's response to mold/mildew in a front loader, you do have to wipe down the rubber ring on the door, it only takes a second. I leave the door open after doing several loads to "air it out" overnight sometimes. A friend told me to add baking soda to every load, and vinegar in the softener compartment which keeps the clothes and unit fresh. We bought my mother-in-law an awesome top loader in Ecuador. It was an LG also, and had NO MIDDLE agitator, that is what kills the clothes as they tend to get bound up on it and can tear or stretch. It had similar features to my front loader, and the price was in our budget. Whether you decide on a top or front loader, think about reach too. If she needs to bend down for a front loader, and she has a bad back or knees,you'll need to put on a pedestal, or with a top loader that she'll have to reach into it. What is better for her body, height and health. BUT do get one without the middle agitator.
Good luck! (and go to Abt, they are great)
Also, if she's hanging clothes to dry and has a wrinkle problem, I throw my stuff in the dryer for about 5 minutes before hanging to dry to get the wrinkles out before hang drying.
