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.
The solders have been known to break loose so check to see if they just need a touch up solder.
You can order a new control board from the Sears PartsDirect website.

Here's how to do it: http://media.fotki.com/1_p,wkwdftgtbkdgf...
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.
