F21 is too long to drain:: (more than 4 mins) Check your drain hose outflow into a couple of 5 gal buckets it should flow pretty fast. If not, there is both a suds sensor and the water level pressure switch that can be causing the problem. Since you do not have SUDS showing on your control panel I am assuming the suds sensor is fine. The water pressure switch itself can cause the problem even if you hear audible clicks when testing with an external hose. A clogged drain pump strainer can do the same thing. Lastly... the obvious... is the drain hose kinked???? Good luck and hope this helps.
Where is the drain plug striner located?
Hi
F21 error means that the drain time has exceeded 8
minutes; this will turn off the water valves. Press PAUSE/CANCEL two times to
clear the display. If errors still remains then please check the drain hose and
make sure it is not plugged or kinked. Disassemble the washer by removing the
back from the washer and check the electrical connections at the pump and make
sure the pump is draining. Also inspect the pump filter for foreign objects.
Before disassembling remember to turn off the power and disconnect the washer.
If it still doesn't help then there is an issue with the pump and you'll need
to replace it. Hope this helps... Please post back if you need more
information.

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.
