My WP Duet front load washer has an F02 fault. This is a drain fault.

Are there any common causes for this fault?

Is there a solenoid that controls the drain function?

Washer is 6 years old.

Fixed this one myself. The washer has a quick access drain port cover. All you have to do is lift the front of the washer and remove 3 screws to remove the access panel. You will see a 3 or 4 inch diameter drain port cover. The cover easily screws off manually. When I removed the cover, I found a sock, parts of an ink pen, and some money - yeah! Once removed, the washer works fine.

Don't do this yourself if you do not have a safe way to lift the washer. It is very heavy and can injure you if it should fall.
