Well, the truth be said, 10 years of operation without a single glitch is either a product of sheer luck (i.e. one golden batch in the production line), or the brand really went serious with quality and the strategy at the time didn't include the need for recovering the same consumer soon in the product life cycle.
I can say this from the Whirlpool dishwasher model ADP 6837/1 that I have been using since 2009. During 10 years it never complained, while we threw dirty dishes at it on a daily basis.
