Product review (1 stars): Quiet initially, but diappointingly noisy after only 1.5 years.
Well, we wanted a quiet dishwasher to replace the 18-yr old KitchenAid that must have been original with the house.  It was very loud and not well insulated.  With a Kitchen that opens to the living room that was a problem.  So, I set about doing research to find the most quiet dishwasher for the money.  The LDF7932ST seemed to fit the bill, and I was impressed when we ran it for the first time.  Could not even tell is was running, when standing right next to it!  We even took advantage of the energy efficiency and purchased the unit with a SECO grant through the state (saved us $80, I think).  So we got the unit for about $800 installed.  This was in April of 2010.  Suddenly, within the last month, the unit started making a grinding noise which has progressively worsened to the point is sounds like a little man on a motorbike is running the rinse cycle!  I am assuming from other reviews and some postings on YouTube, that the motor will need to be replaced.  Being over a year old, but under two, the labor will be on us, but the part should be covered.

We placed a call to LG to schedule service, but they have required that we go through Sears, since that is where we bought it.  We will see what happens when the diagnosis is complete.  More to come later...
