Also here is a list of He2 error codes http://www.applianceblog.com/mainforums/sears-kenmore/10283-he2-error-codes.html
I think the error code you are actually getting maybe an F21 due to there is no listing for F12. use this kink to put the unit into diagnostics and run the diagnostic menu which will give you your exact error code as well. I await your reply
Thank you

Hi
The code F12 means the following:
F12 - No mixed fill. It is likely that the water is not turned on at the taps.
Also Error code F12 is indicating a communications error between cards; Error code F12 is indicating a communications error between cards, this can be caused by one of several things. A problem with bad connections, if you can remove and then replace the plug on connectors, check for loose or chafed wires to motor, they can chafe due to tightness of wires, particularly down to the motor.
It is an electrical problem as opposed to a mechanical one.
Please get back to us if you have further query else please accept the suggestion.
