I think having high quality appliances is partially why Sears tanked... First they didn't sell as many (due to having to compete on price with lower quality / cheaper products), then when they found a way to compete (having Samsung make Kenmore appliances, for example), they lost the quality and the last reason anyone would opt to go there over Costco or Amazon or Home Depot.
I bought a matching Washer / Dryer set from Costco. Then the next year I bought a Fridge and Dishwasher from LG there too. For the first three years or so it was fine, but about 5 years in I think they all have issues. My house is about 20 years old, and the Dishwasher I replaced was the original... so it lasted 15 years. I can say that the new (and fairly top of the line) Dishwasher has more issues at 5 than the old builder-grade one had at 15. I really regret not getting a Bosch...
But even up into the 80s and 90s Sears / Maytag were known for selling top quality goods that didn't break. Here's a cute commercial.
