New LG front load washer / dryer front loading set last year. Rock solid so far.
Just replaced 10+ year old Frigidaire Gallery gas range (computer board), dishwasher (bad pump) and microwave this year with GE Cafe appliances (so, not high end, but, not low end). Interesting how the Frigidaire range and dishwasher both went out around the same time. Microwave was fine, but, wanted to match the set. Original Frigidaire fridge rusted out the back/ leaked due to a condensation design flaw 3 or 4 years ago. Replaced with a Whirlpool. Solid, and the Icemaker works/ no issues.
First replacement GE Cafe range had a bad numeric control panel- didn't notice until day after install (installer only tested burners), so, it took over a month w/ HomeDepot screw ups to get a replacement. Good so far. Dishwasher is a little bit strange w/ random beeping, so, turned the sound entirely off.
Didn't really look at the higher end stuff, but, seemed like the GE's, Kenmores, Whirlpools, Samsungs, LGs all had similar units/ price ranges. Sales/ Installer said 7-8 years these days is doing good. Probably some level of 'planned' obsolescence in all of them...
