Find a vendor that targets customers who lose money if the appliance fails, and is unable to be quickly repaired.
So far, this has been a good way to locate Vulcan Ranges, SpeedQueen washers/dryers, and True refrigerators.
Now...there are drawbacks to this approach. Many of these brands don't target the price-point, convenience features, or aesthetic that consumer brands do. But, if the price is right, you may find something reliable you can live with.
