I just went through the same problem with wash interruptions due to F11 codes on my Kenmore He3t. Sometimes I would show the dl (door lock) code as well. Tried snugging electrical connections and the plug/plug in techniques and managed to limp along for a while that way. After checking for pricing on a new washer control board ($210 best price) I opted for a remanufactured one through Ebay fulfilled by Partsimple.com for $81. The part arrived two days quicker than the estimated delivery, installed easily and solved my problem/s. The part number is 8181692.
"Had this exact problem. My Kenmore elite is 20 years old. I ordered the new housing communication panel part number 46197030068 off of eBay watched a YouTube video of how to change it out and voila operating normal and no code. All for $280 with 3 year warranty. My family kept saying just get a new one but I was determined to fix it. What did I have to lose. Thanks for the information.
i drain out the water and particules on the filter at the bottom of the washer and connect it again to power and the door unlocked and is running again.
