Our front-load Whirlpool washer has stopped draining, and is now giving an F-21 error code. The owner’s manual says it is a drainage problem, (no kidding). What can we do to fix this problem?
See the attachment for the tech sheet.
It has lots of possible causes/fixes for this error.
The F-21 error listing is not in any particular order so read through them and do what is easiest first.
