“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.

If the above procedures do not correct the problem, it is recommended by the manufacturer to replace the drain pump.

SOURCE: what does code F21 mean
The water is taking too long to drain from tub, remove the lower acces panel on the front of the washer and unscrew the round cap which contains the strainer filter. Take filter out of the housing and see what has all collected you may be very surprised what you find, let me know if this solves your problem or need more help

Hello & Welcome to FixYa
F21 error is displayed when the washer is unable to drain, press PAUSE/CANCEL button twice to clear the display. After this please check the drain hose and drain pump filter for any blockages and make sure it is not clogged with foreign particles. You can also check the drain pump to verify that its working. Please get back to me if you have any other questions.
