I took the lower front cover off the washer and found the maintenance publication that the manufacturer leaves in washers and dryers when they ship from the factory. F21 fault code means it took longer than 8 minutes for the washer to drain. I opened the filter cap and discovered many things in there. A bunch of hair, some coins, a pen, and a pair of tweezers. I also found the impeller on the pump motor damaged. I put it back together and it worked for one load but ultimately I had to replace the pump. It's a really easy job don't be intimidated. One note before removing the filter cap make sure you have a 5 gallon bucket to catch the water that remains in the washer. If you need to uncouple the filter/pump from the washer to make sure you can dump the water into the bucket rather than into the bottom of the washer. Makes for a much easier clean up.
The only bad thing I have to say about my experience is about FEDEX. Their delivery person must not have any common sense. I live in the country in the middle of 56 acres. My driveway is 1/2 mile and ends at the deck that leads up to the side door of the house. There is no path to the front door of the house and it is very obvious the front door is unused. Guess where the FEDEX driver keeps leaving my packages? The first time I ordered from here I thought I would never receive my part. I finally found it a week after it was delivered next to the front door. That was the first time a package had been left there. Now I know the FEDEX driver is an idiot so thats the first place I look when expecting a delivery from FEDEX.
