I have not owned a dishwasher and a while. The last couple that I had years ago you had to pre-wash the dishes, so what was the point. This dishwasher did a great job even on the baked on! I have an open floor plan to the house, and running of this dishwasher did not interfere with conversation or hearing the television.  With the extremely simple one button design, there's no thinking about what is needed to start the machine, this would be excellent and senior type environments.
