Kenmore Elite Dishwasher Error Codes. After performing the three button protocol, close your dishwasher door and open it again. Looking for same answer to post by fd willis on 4/24/17, having same issue, checked float, drain hose, can't get diagnostic mode to clear f6e4 error, will wash for quite a while, 20 minutes or so, then it will just stop with pause/start blinking, if you press start it will run but the display will not show the progress bars and it will run for a while, stop, run for a while, stop, etc.
Damaged or corrupted memory on control board. This light blinks when a cycle has been interrupted because of a power outage or because someone opened the dishwasher while it was running. After performing the three button protocol, close your dishwasher door and open it again.
