I have had Whirlpool appliances in the kitchen and garage for 20 years now. I'm a believer in their quality, so I specifically look for that label, or the Whirlpool-made no-name brands.
Our Whirlpool made dishwasher had one of the wheels that pulls the top tray out, brake. I called them up and they sold me a replacement part over the phone for less than $10. I was surprised that they were obviously not trying to make a ton of cash for a replacement part like that. 60 seconds after opening the package, it was working as normal again. At any rate, this dishwasher has now been running/working since I moved into this house in 1999 or 98 (can't remember which).
