Tracy,
This error code indicates that the door needs to be opened and closed.
The F26 code may appear the first time you try to use the washer. Open and close the door to clear the display.
The F26 code may also appear if the washer has run three cycles without the door being opened. Open and close the door to clear the display.
If opening and closing the door does not remove the error display, press Pause/Cancel twice.
The above procedure is the specified way by whirlpool technicians to clear the error code
