I've had 2 washing machines die in as many years, and the electronics were encased in silicone.

Of course, a repair involves replacing the entire proprietary electronics assembly (multiple PCBs, and plastic frame), and is just not economical, so the entire machine, valves, motor, steel drum and cabinet, are written-off because a mosfet failed, or whatever.

If the electronics were standardized and modular, even if encased in silicone, there would be an economic case to replace just failed modules.
