Keep getting f2 signal on kenmore elite quiet pak he3t

F2 and F02 error are one and the same. My daughter was doing a load of towels in my Kenmore Elite HE3t front loading machine, when I went back to put them in the dryer the washer had a load of water in it and an error reading of F02. Checked the manual Could not find anything wrong with the Drain Hose?
 
These are the possibilities for that error code at one web site:
 
Press PAUSE/CANCEL twice to clear the display.* Check the drain hose and make sure it is not plugged or kinked.
* Check the electrical connections at the pump and make sure the pump is running.
* Check the drain pump filter for foreign objects.
* If the above does not correct the problem, replace the pump.
F02 is long drain.
Just because it came up doesn't mean there's a problem, it simply means there was a failure during the cycle, if it returns on a regular basis, you have a problem.
F02 error could be caused by the over use of soap, you need to make sure your using 2 tablespoons of HE soap, 1/4 cap at the most.
Over sudsing, could cause the water pump to run longer, the pump is designed for 15 min duty cycle which means, 15 minutes on to 45 minutes off. The computer may sense too much soap, and continue to pump. HE soap will cure that, along with SUD error, possible F09 (overflow condition), you may also notice the timing is wrong, HE soap works well in these machines and F/l washer go hand in hand
if the F02 returns the remove the 3 torx screws from the bottom kick panel, and remove the kick panel, right there in the middle you will see a big round handle, turn it and then slide it out, have some towels ready, there will be some water in there, and check to see if you have any thing in there that will slow water flow, tooth picks and other "floating" items may jam the impeller.
