Its difficult to find any evidence relating to bacteria in water systems, but its certainly not 100% disinfected, or free of bacteria.

The problem with washing machines is they are devices that are rather difficult to disinfect. If you were to take a brand new washer, as in never had water ran through it, you would probably see a drastic reduction in her results. However, after a few uses bacteria from the air, cloths, water, and other sources will eventually end up in the system. If the system is not vented, then wet spots will exist throughout each washing cycle carrying with it any bacteria.

With that said, what I am suggesting is the washing machine is the culprit for bacteria from city water, which is not 100% bacteria free. Add in the fact that High-Efficiency washers use substantially less water then older units, and you have a perfect bacterial soup machine. Older machines used more water, which allowed for further dilution and flushing.

Would the situation be the same if the water was 100% free of bacteria with a brand new washer that would be dried completely after each use?

If you had read the article, you would know that (a) the water was free of bacteria, (b) she tested an old HE washer, an old normal top-loading washer, a new HE front-loading washer, and a normal front-loading washer and (c) the problem wasn't the washers.

And she tested the washer and dryer too.

She didn't claim the water was free of bacteria, just that it didn't grow anything on the agar plate.
