I've had this same exact problem and that's why I'm at this site.   I have had success with holding the start button and hitting the door right over the place where the switch is on the other side.  That worked good until today so I've called a service tech to come out later this week.  Give that a try and maybe it will work for you.

MY WASHER WAS DOING BASICALLY THE SAME THING. I HAVE A WHIRLPOOL FRONT LOADER MODEL #GHW9460PL0. MY HUBBY REMOVED THE 3 SCREWS FROM THE BACK OF THE WASHER, UNPLUG IT FIRST, AND TOOK THE TOP OFF. WE THEN CAREFULLY UNPLUG THE WIRES AND REPLUGGED THEM BACK IN 1 BY 1 SO U WONT GET THEM MIXED UP. WE THEN TRYED IT, AND THE CONTROL LOCKED LITE STAYED LIT. HE HELD THE SIGNAL CYCLE BUTTON IN FOR 3 SECONDS AND THE LIGHT WENT OUT. WE THEN TRYED RUNNING A CYCLE AND SO FAR SO GOOD!! GOOD LUCK!
