If you are experiencing drainage issues and cleaning the pump does not work, you may have to replace the drain pump. You will usually experience an "F2", "SUD" or "F21" error code (depending on model number) for a drain blockage problem. Since this error code occurs when the drain cycle exceeds 8 minutes, if the pump motor or impeller becomes damaged, the pump will not pump at the required volume and the error code will continue to occur. Replacement pumps can be purchased on line at:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

Prices vary between these sites, so shop all of them for the best deal.

NOTE: Make sure you also check the drain hose and the inlet hose that runs from the bottom of the wash tub to the drain pump. Small articles of clothing can commonly get lodged in this area.

If you have any questions, please let me know. I hope this helps you.
