I have used Kenmore washing machines in small towns in Maine with water so hard that the filter I had attached to my machine was full of rusted iron particles, but it still did an excellent job for 31 years. The only reason I don't still have this Kenmore washing machine is because I left it for the new owners of my home when I sold it in 2005. The first thing I did upon moving to Idaho was to purchase another Kenmore washing machine and dryer to continue a tradition of satisfaction.
