CR tests washers with both a standard 8-lb. load and one at the machine's maximum capacity, both using warm water and the default Normal cycle with no added options. These scores averaged together make up the machine's washing performance (cleaning) score. Sometimes washers with a middling washing score do fine with the 8-lb. load but falter when loaded to full capacity.
I understand peoples' frustrations with CR; they've really short-handed what used to be a lot of rich information concerning their tests. And I, too, get sick of not being able to tell one issue from the next because they all have either a phone, a computer, or a TV on the cover.
Having said that, I have both a magazine subscription and an online subscription and I always check their ratings before buying. It's a good place to start, and I certainly trust their tests more than I do manufacturers' claims.
I also find user reviews of limited use, as people who generally dislike, misuse, or get a defective product are the ones who post, not those who like the product. I love my LG dishwasher; it cleans better than any machine I've owned (Whirlpool, KitchenAid, Maytag, Kenmore/D&M), is very quiet, a miser with water, and has given me not a single problem in four years of very hard use; but I've seen scathing user reviews of the same model. It makes me wonder if we're even talking about the same dishwasher!
CR is far from perfect, especially for those of us who'd like to see a return of the long-form text that used to accompany tests; but I'll keep my subscriptions and use CR as a starting-point for purchases.[this post was last edited: 12/2/2012-19:54]
