Product review (1 stars): Think twice before you go with Viking.
I bought the Viking Stainless Professional Dishwasher VDB451SS  thinking that it was a step up.  Well....  The very first day I had to call a repair man who came out and he had to dismantle the thing to put a computer chip in the bottom of it.  Three months later the start button had to be replaced.  About a year later another computer chip had to be replaced followed by the top rack falling apart that had to be replaced.  Then the repair man had to come out to replace another chip because the machine thought it had a leak and would not start.  Now in the third year I am without a dishwasher for three weeks waiting for a part to be made in two more weeks for water pressure detection.  In total I spent $2000 for this machine and have been without a dishwasher for at least two months in three years.  .....  Maybe that is why this model has been discontinued.  Viking is not what it used to be.
