We have an open floor plan and a Kenmore Elite dishwasher with extended warranty. It works well and is so quiet it does not interfere with TV or music. I mounted it well above floor level in an island next to a sink. By raising it you don't have to do deep knee bends or touch your toes exercises to load/empty the lower rack. The cord that takes the weight of the door to springs to make it easy to raise and lower is the only warranty repair needed in 5 + years. It has delayed start option so if you don't want to be able to hear it at all just set it to run after bedtime. Consumer Reports is a decent source of info re dishwasher performance, longevity, price, noise , etc. We have had many brands over the years but are now hard over for Kenmore top of the line appliances and their extended warranty. We have had very few problems but they are always fixed to our satisfaction in a reasonable period of time. When the repair guy comes he checks out ALL the Kenmore appliances, adjusting burner flames, testing frige and freezer temps, even cleans out the dryer duct of lint and on and on.
