The wax motor and board are probably failed, however when your machine did spin did you say it sounded like a rocket taking off? I always compared it to a turbo prop taking off, but either way it sounds like your bearings are Kaput. Is there any wobble to the tub? Meaning, can you reach in and move the inner tub independently from the outer tub? If so your Bearings and possibly your tub support assembly have failed. This could contribute to a Motor control failure along with the main control and wax motor in the door lock.
