Whirlpool Duet F11/11F error code resolution

Our washing machine has been randomly throwing this error for some time so I did some googling and stumbled upon this thread: https://www.flickr.com/photos/mysteryonionpatch/471156850.  I went ahead and took the CCU out and low and behold I have the same exact issues, the carbonized relay and a cracked soldering job.  Whip out my desoldering gun and WD40 + alcohol the contact and it looks like the machine is good as new..yay!  Saved $300.  Here's my post on facebook: https://www.facebook.com/photo.php?fbid=10152823024811000&set=a.64395720999.103430.507985999&type=1
