I'm going to offer a counter narrative here based upon my experience. I have LG appliances and they have fairly reasonable "fix everything wrong" prices. It's not literally everything, your bells and whistles might not work, but if you want just a washing machine, just a dishwasher, or just a fridge/freezer, it will be less expensive than the cheapest new option out there.

When our fridge stopped fridging, we got it fixed for $300: this included replacing the compressor and the coils. When our dishwasher stopped washing, we paid $250 to have 3 or so things fixed at once. And so on.

I don't know if any appliance makers offer this, but if LG still offers it when we eventually replace, they're going to be on the top of my list.
