DE Error Code was flashing and the washer would not start until you hit the start/pause button over and over again until it accepted the door was closed and the washer would begin to fill.
I first watched the video, whatever you do, before you start tearing apart your washer, WATCH THE VIDEO. I am not kidding, the video was longer than it was to remove, replace, reinstall and start a small load to make sure the washer was working.
If you do not own a pair of locking pliers, go to the hardware store and pickup a pair. It will without a doubt, make the last part of pulling your retaining wire sooo much easier. For all of my appliance repairs in the house, appliancepartspros.com is my first stop. Good luck, again this is on a scale of repair a 1 in simplicity. If you have never repaired your own appliances, this is a perfect start for taking the plunge.
