Great project and writeup; just one more example why we should always be cautious about "smart" devices, for that smartness nearly always aimed at eliminating customers choices. I wonder what does the device electronics do beyond checking for the original cassette and its eeprom; it doesnt seem it would have to do anything more complex than opening water, and detergent valves/pumps for a certain time while keeping the right temperature; nothing that even the simplest uC and couldn't do; a further development could involve probing all signals at sensors and actuators during normal operation, then getting rid of the old electronic to allow the device taking detergents directly from the tanks, so resetting the cassette eeprom wouldn't be needed anymore because there would be no need to insert one. This of course would invalidate the warranty, but for some of us that is a plus point:)
