The washer electronically signals the matching dryer to indicate which wash cycle was used and the dryer automatically chooses a corresponding setting -- a unique but not especially helpful feature.
I'm almost obsessively opposed to appliances with unnecessary features that cost more money to begin with and have more things to break. (I inherited this "prejudice" from my dad.) The surprisingly new and incredibly expensive range and dishwasher that came with our house (they were both a year or two old when we bought the house just three years ago and cost around $1000 each) have firmly entrenched this concept into my psyche with their multitudinous break-downs and replaced parts. We try to find the very plainest possible model of very solid machine/series and this has served us quite well.
I should probably note that Ria will be particularly excited about the new washing machine (it was a Consumer Reports "best buy" and incredibly inexpensive - and on clearance at Home Depot) we picked up this morning as she runs most of the laundry in the house (though she gets to listen to Chesterton audio books during this tedious chore). Our current system requires the washing machine to be manually filled with hot water from a hose in the sink as the hot water valve in the machine had rusted "on" and had to be shut off at the source (to prevent additional basement floodings). Happy day!
