I love my HE washer! I think they're great ... I've had no problems with performance, and I like that they save water and energy as well.
Most detergent manufacturers offer a variety of HE products now, for example Tide
. They also offer a cleaning product
for your HE machine ... although since you just got yours you really won't need it at this point. I've never used it myself, but my mother has had her machine for several years now and has used this product occasionally.
If you're looking for a natural/environmentally friendly detergent, there are several available ... one that I know of and have had good experiences with is by Greenworks
Anyways, hope you enjoy your new washer!
