It is pure madness that we build appliances intended to be sent to the landfill.
Refrigerators are almost entirely disposable. Leaks in refrigerant coils embedded in foam insulation are not repairable. Older designs were better but in general, refrigerators haven't had a lot of design love with respect to maintainability. There's a lot of headroom for improvement. Of course we could start by removing wifi and built-in cameras and remote bricking capability, but that's a separate thread.
Dishwashers are frustratingly simple to repair. So few components and such a simple mechanism. All we really need is a standard controller, pumps and chassis. With a universal design, an entire blue-collar segment of appliance can become viable again.
