The F01 indicates a failed electronic machine control board. This error code can sometimes be caused by a glitch or power surge through the electrical lines. You may be able to clear this code by unplugging the washer for 5 minutes. If the code returns after plugging the washer back in, then the electronic machine control board will need to be replaced.
You can order a new control board from the Sears PartsDirect website.

Be sure to unplug the washer before accessing internal components. When you access the control board, I recommend transferring the wires from the old control board to the new replacement control board one connection at a time. Once you have all of the wires transferred, remove the old control board and mount the new control board in the washer. Reassemble and test the washer.
