I've proudly kept my [who knows] dryer going by replacing the heating element twice, and maybe a belt once, too. Cheap, easy, only down side was when I slipped removing a screw and sliced open one of my fingers on the sheet metal. Healed fine, but scar tissue made my knuckle bigger, which is annoying.
Our washing machine broke its spider arm (almost certainly after losing a shock absorber or two). I thought about trying to replace that, but decided it was more than I was up for.
Our fancy Asko dishwasher, on the other hand. Tore that thing out after maybe only 4 years. What a headache. Bosch has been kicking right along ever since without a problem.
