This is quite a machine
 It's so quiet if it didn't have lights nor have chimes on it you would never know when it was running or when it was done.  I wasn't sure about the door opening on its own at first,  but it does seem to help the drying of the dishes and plus it's a nice visual that the dishes are done with just a quick glance.  I would recommend this to anyone that would be looking for a new dishwasher.  We're really love this dishwasher, it was a great addition to our home.
