This was our second model of this dishwasher---we bought it in June 2016.  The first model quit draining three weeks after we bought it, so we replaced with an identical model.  Three years later, the bottom wash arm is warped from heat and hits the bottom rack, and the dishwasher quit washing during a cycle.  It fills and drains but no longer washes.  I know the unit has a year warranty but it should not have quit this soon.  When it worked, it performed very well.
