Funny you posted this, I've been wondering if other people liked their high efficiency (HE) washer and dishwasher. My MIL has a Maytag HE and she likes it ok but here are my thoughts on HE in general. Our washer is the LG Tromm front loader and compared to non-HE washers, I don't think it cleans very well. I have to stain treat every item, and with 2 little kids, that's a ton of work. Also, it doesn't rinse very well. I don't over-use detergent and only use HE detergent, but even with the extra rinse, when I wring out my washcloths later, there's always a lot of suds. Any little bits of food stuck to the clothing will not rinse away and will be left somewhere on the clothes at the end of the wash. So yes HE saves water, but when you only use about 6 inches of water per cycle, things are not going to get rinsed very well. The other issue with many front loaders is that if you ever forget to add an item to the wash, you can't stop the cycle to put it in. Some machines also get mold in the compartments where you pour the detergent, bleach and softener.
We have an Asco energy efficient dishwasher too and that's funny that someone else loves theirs - I hate it. It's the worst dishwasher I've ever had. I have to pre-wash and pre-scrub everything or the dishes come out with food still on them. We're not talking about days-old dried on food, but just little bits of food residue that's still fresh. An old apartment I lived in had a GE Profile dishwasher which worked great and the dishes didn't need to be pre-rinsed.
My general advice to you is that some of these fancy brands look sleek and have great features but aren't necessarily better or more reliable, and if you ever need repairs, it'll be harder to find a repairman who knows these machines. I know someone with Thermador kitchen appliances which are high end and they stopped working after not too long, and she can't find a repairman near her. But if you get a more mainstream brand, it'll be easier to find someone who can fix it well.
I know it wasn't exactly your original question but hope this helps a little.
