Roughing It: Homemade Laundry Soap - For HE Machines?

I've had a question on wether you can use the homemade detergents in High Efficiency Washers. Here is what the site I got the recipe from says:

Can You Safely Use Homemade Laundry Detergents With A High Efficiency Washer (HE Machine)?

• I have no experience with this but there are lots of comments that say it’s fine to use. Be aware that using anything other than what your machine manufacturer recommends may void your warranty.
• Go through the comments in the original post and you will also find several recipes offered and recommended for HE machines. (see below, comment by "Troy")
• Homemade detergent is low sudsing which is important for HE machines.

Hello Everyone,

For the last year, I have been using the following Mix for my Sears Kenmore HE front loader:

3 bars Fels Naptha
3 cups Borax
3 cups Arm and Hammer Washing Soda.

Grate the Fels Naptha, then put in a food processor with a chopping blade and chop until fine.

Pour into a large bowl with the Borax and Washing Soda and stir until combined.

Use 1/4 cup in a HE front loader, use 1/2 cup in a top loader. In my HE front loader, it dissolves perfectly

I use Vinegar as the fabric softener and add Mrs. White’s Liquid Bluing for the Whites load. The whites come out wonderful, the colors are bright and clean., and best of all, it is better for the environment.

I also found this info:

Regarding High Efficiency (HE) Front-Load Washers

You may have been told you need to use “special soap” for your HE front-load washing machine. Let me enlighten you as to why. HE front-load washers require “special soap” for one reason and one reason alone…low suds; because they use less water, they require soap that is less sudsy. The good news is, the homemade detergent in this recipe is VERY low suds. Just make sure you use the recommended amount of detergent. http://diynatural.com/simple-easy-fast-effective-jabs-homemade-laundry-detergent/

PROGNOSIS:

Most of what I have read by impartial observers and those who have been using it for years say a resounding YES to homemade detergent in HE washers, with the odds slightly more in favor of the liquid detergent.
