When we moved to Texas, we sprung for the LG front load washer with matching dryer. It had one of the best ratings in Consumer Reports for energy efficiency, cleaning capabilities, and value.
I have not had any problems with either unit and absolutely love them. The normal cycle for washing is a bit long but everything comes out clean. It does such a great job in getting the clothes clean that I usually run most items on the speedwash cycle which is around 30 minutes. One of the best things about it is that it is extremely quiet - even on the spin cycle - and clothes come out of the wash barely damp so they dry in half the time.
My favorite thing about the set is the capacity of each unit. I can wash all the jeans for a family of 4 in one load and still have some room. It saves me so much time on laundry day it's almost ridiculous. I have seen a little mildew on the seal which wipes up easily and can be controlled by keeping the door open every now and then. Sometimes I'll spritz a little bleach on it when I do a bleached load such as t-shirts and socks.
We also bought the pedestals for underneath which have roomy drawers perfect for storage. And they elevate the units off the floor so I don't have to stand on my head to get clothes out.
