As with the other appliances, this replaces a 14 year old GE Monogram Series dishwasher.  The Monogram has been a great dishwasher, but was starting to get louder and louder and just doesn't clean like had in the past.  So out with the GE and in with the Frigidaire.  I haven't installed the Frigidaire yet, however a neighbor has a kitchen full of the same Frigidaire Professional appliance, including the dishwasher, so I have first hand knowledge of how it performs.  It gives you very nice clean dishes and is ultra quiet.  I can't think of anything to complain about and neither can my neighbor.  Clean and quiet, what more can you ask for?
