“F21” (AKA SD) is a Long (SLOW) Drain error (LD). If the drain time exceeds 8 minutes this error code will be displayed. In addition, a “SUDS” error may also be displayed. This may be an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:
1.First, attempt to unplug the washer for at LEAST 30 minutes to reset the Central Control Unit (CCU). Sometimes this is all that is required to correct momentary glitches with the unit. If the error code returns, proceed to step 2.
2.Check the drain hose to make sure it is not kinked or clogged.
3.Check the electrical connections to the pump and ensure the pump is running.
4.Remove the drain pump filter and check for foreign objects and/or debris.

Hi,
"F21" is a Long Drain error. This occurs when the drain time exceeds 8 minutes. You will need to remove the bottom panel under the door by removing the two screws at the bottom edge of the panel. First, check the electrical connections to the drain pump and make sure the pump is running. Check the drain pump filter to make sure it is not clogged with debris. This is a very common problem. HINT: Before removing the drain pump filter, pull the drain hoses from the standpipe at the wall and use a shop vac to pull a vacuum on the drain hose to get rid of all residual water from the pump and drain lines. This is also a good way to get rid of minor clogs. If you do not own a shop vac, be prepared to lay down some old towels and soak up some water. There's quite a bit of residual water in the wash tub and lines (this is normal). In addition, check your drain hoses to make sure they are not clogged or kinked. If you check everything and still have the error code, replace the drain pump. Replacement parts can be found at searspartsdirect.com and repairclinic.com. Just type in your model number in the search menu. I hope this helps you.
pls rate my suggestion....
SOURCE: What does code F21 mean on a Kenmore HE2 plus
it stands for longer than normal drain interval,press "pause/cancel" twice to clear, if it returns then look for obstructions in the water drain from the basket all the way to the drain in the house,or possibly it could be a bad washer drain pump
SOURCE: Kenmore HE2 Plus error code F21
F21 Is a slow or long drain.
Things to look for kinked drain hose,
Plugged or obstructed drain hose, Possible pump filter screen clogged,
Least unlikely is a drain pump failure.
The pump filter screen is
the most common it gets plugged with lint, coins, hair etc. It can be
cleaned by the owner however is is a very dirty messy job and if you are
not very careful you can end up with water everywhere. If you want to
attempt it let me know. If there is anything else I can do to help
please let me know.
