Earlier I reviewed this dishwasher, but did not have all the facts. Upon reviewing my review I observed video and pictures that show the versatility of this machine by simply adjusting the racks up and down. This may not have been clear in the book. I now say this is the overall best quality dishwasher I have ever owned! It has so many options on both space and cycles. I also like that I can put plastic storage containers in without fear that they will melt. And yes, it is so quiet that I now check the floor for the little red dot to make sure it is running.
