This is why I manufacture a lot of my own appliances these days. The parts are all available online, and I trust my engineering moreso than manufacturers these days.
I would be very interested in open-source plans like this, and joining (or helping form) a community around the idea of appliances built to last, or more importantly, using modular standard parts and designed for repair.
