Only had hooked up and running two days.  So far I am pleased with the level of noise and cleaning ability.  I will highly recommend using Cascade Crystals (old school).  I have used the liquids from other vendors and they do not clean as well as Cascade Crystals.  Generic "Green" cleaning supplies will not clean in this GE model.  The machine is just temperamental with cleaning supplies.  I had similar issues with other brands too, but mainly GE dishwashers.  I have GE dishwashers lasting in my rentals 8-9 years.  That's very good for rental.
