"F21" is a Long Drain error code. This indicates that you have an obstruction somewhere in the drainage system. In most cases, this means you probably have a clog in the drain pump. The following link explains:

You may have something getting caught in the pump impeller and slowing it down. Included is a follow-on link that explains how to check the drain pump to clean. You may also have to remove the inlet hose that runs from the bottom of the wash tub to the inlet side of the drain pump. Debris can commonly clog in this area as well causing the drain cycle to fail.

NOTE: If these preliminary measures do not correct your problem, you may have to replace the drain pump. It does not take much to damage the pump impeller or motor. Since the error code is generated if the drain cycle exceeds 8 minutes, if the pump is damaged and can't pump at the required volume, the error code will continue to appear until the pump is replaced.

NOTE: The "SUDS" error can also commonly occur with the F21 error code as this is can be generated when air is sensed in the drainage system.
If the door won't open it could be jammed due to the program being interrupted.

If you have questions about this repair, or require additional assistance, please let me know. I hope this helps you.

"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.
