After lots of research online and considering buying a new washing machine, I finally came across a repair story on here, appliancepartspros.com. Someone with a similar washer and the exact same problem replaced the rods in the washer. So for under $60, it was worth a shot. The rods we took out looked the same as the ones we put in, but once we replaced them, the washer worked perfectly and we haven't had a problem since. Delivery was fast and the instruction videos made replacing them quick and easy.
