This is our seventh (!) dishwasher we've purchased for our home in 36 years.  The first one lasted almost 20 years so we've been through quite a few in the last decade or so.  We were beginning to think that all the failures of the variety of appliances we purchsed were due to planned obsolescence.  The last one, a GE, died after only two years.  We decided to purchase up and have not regretted the decision.  This dishwasher is quiet, does a fantastic job even on the 60 minute cycle and seems durable.  I don't think we will ever buy anything other than a Bosch in the future...but to protect our investment, we opted for a 5 year warranty.  Just in case.
