Sadly my strategy has been to buy the cheapest possible appliances, understanding that they will fail within 2-3 years no matter what we buy, and then just replace them with less hard feelings. Disposable appliances indeed.
Did this with a display model Whirlpool dishwasher from Home Depot which we bought for $200. Had some dings on the stainless surface, and I was sure it was going to have a short life given it was a display unit. But ironically at this point it's made it twice as long as the fancy Samsung unit it replaced.
