My whirlpool washer duet sport is not draining water out and displays error code f-21

Whirlpool Duet Sport Washer will not drain 21 error

Drain pump may be clogged or need to be replaced may run but not pump blade stripped in pump

Clean the drain filter, located under the washer door

The following list of codes indicates an electronics communication problem with the washer: - Duet HT washer - F01, F03, F06, F11, F23, F24, F27, F28, F29, F30, F31, F32, F35, F42, F61, F62, F63, F64, F65, F70, F71, and F99

If Pause/Cancel does not work:

1. Unplug washer or disconnect power for one minute.
2. Plug in washer or reconnect power.
3. Re-select the cycle and press Start.

NOTE: If the error remains on the display, call for service.

I would first replace the door latch/lock assembly, a number of users have and it fixed the F-11 error code completely. Its the cheapest part for this problem.

Hope helps.

"F21" is a Long Drain error. 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.

Unplug the machine. Unscrew the 3 screws under the front edge of the washer. The service technician manual is attached to the panel that slides down and off. Find F21 code. See suggested procedures. Note: My drain pump filter had a baby wash cloth in it along with some change that was disrupting the flow. It is exceptionally easy to remove, clean, and reinstall. Just line up installation notches when reinstalling. Whirlpool should have mentioned this filter in the User & Care Guide, but I could not find it anywhere in there.
