Summary: We have been using this Viking dishwasher (with custom panel) daily for almost 4 years. The upper & lower racks started to show rust spots about a year ago. I looked into replacing both racks and was astonished to find out that they cost approx. $260 EACH!!!! I decided to wait and see if the rust became a problem before spending almost $550 to replace the racks. A piece on the top rack has actually rusted through and is now 2 pieces.
