Whirlpool Duet Washer F21 Error

Troubleshooting and Repair - F21 Error Code - WFW9200SQ00

If it takes longer than 8 minutes for the drain pump to empty the washer tub the control stops the cycle and reports this error. This problem is usually easily resolved by cleaning out the drain pump filter trap. If the drain trap is clean and the problem persists it could be a bad drain pump or clogged hoses in the drain system. The video shown below shows how to clean out the drain pump trap. First remove the bottom access panel on the washer. There are three screws at the very bottom on the lip of the panel remove those and the panel will come off. Then follow the video.
