Kenmore Elite error message F 02

Here is what the manufacture says about F02 - Below this are my comments

If the drain time exceeds eight minutes, the water valves are
turned off and “F/02” is flashed.

Press PAUSE/CANCEL two times to clear the display.
NOTE: After four minutes the “Sud” error will be displayed,
then four minutes later the “F/02” error code will be
displayed.

Possible Causes / Procedure
1. Check the drain hose and make sure it is not plugged
or kinked.
2. Unplug washer or disconnect power.
3. Check the electrical connections at the pump and make
sure the pump is running.
4. Check the drain pump filter for foreign objects.
5. Plug in washer or reconnect power.
6. If the above does not correct the problem, go to step 7.
7. Unplug washer or disconnect power.
8. Replace the pump.

Phil's comments---->
If you washed a rug with a rubber backing or small articles like baby socks you may have a plugged up pump. To access the pump lay on the floor and remove the 3 screws holding the lower panel of washer on. Pull down and out on the panel to remove. Lay out a lot of towels under the unit, I mean a lot... Look in the center for a white cap about the diameter of a large cup, it will have a handle on it to turn, turn this left(counter clockwise) to unscrew. This will unscrew and pull out, but be careful when it comes out so does all the water. Clean out the trap that is in your hand and anything you see or feel in the sump area the trap came from. Reassemble and test. If this does not work you will more than likely need a new drain pump, that is the component on the right of that trap you just cleaned out.
