Every now and then, our fairly high dollar Bosch dishwasher (which we really, really like, otherwise) will just lose its mind. Turn on. Seems to cycle and… about 90 seconds later beeps to tell us the wash cycle is finished, when it never really began. None of the troubleshooting instructions from Bosch affect it at all, but if I throw the breaker for the circuit the dishwasher is on, wait about a minute and turn the circuit back on–effectively performing a hard reset of its tiny lil brain–the thing works like a champ.
Must be an embedded Windows OS. *heh*
