We lived with an old Sear's dishasher for years.  We had ir repaired once but when the heater went out we stopped spending mney on repairs.  It got pretty bad with the smells.  I replaced the filde once and cleaned it twice.  It was a cheap scratch & dent model.  I did my reserached with Consumer Reports and Wirecutter for the best I could afford.  I settled on the Bosch over Miele and Maytag.  We've had it only for 3 months now but have fallen in love with it.  It's an incredible and efficient cleaning machine.  It has changed our lives since the installation.
