Funny story: The installer took out the old one, installed this one, powered it up and thought it wasn't working. Rechecked everything and confirmed that everything was done correctly but still didn't think it was running. It turns out that it was running fine but it was so quiet that he didn't think it was. As far as cleaning goes, it's fine. The top rack that holds small items like chopsticks is very handy and glad we opted for one that has it.
