We just replaced a Whirlpool front loader and Whirlpool Senseon dryer (about 8 years old) with this Samsung top loader and matching drying.

The front loader left our clothes with a low level mildew stink and the dryer didn't dry them and I had to wiggle wires on the control panel to get it to come on.
The idea that you have to leave the door open on a washer so it won't stink is ridiculous when almost every utility room is the country is a narrow passage to a side door or the garage.
I can't speak to the long term maintenance, but the new units work like a charm.
A few washes and all the previous low level stink was gone from our clothes.
The dryer will beep to tell me stuff is dry and I'm thinking no way, it's only been 15 minutes and it's all completely dry like it should be.
