Googled what was wrong and found video from Appliance Parts Pros of 5 things that may be wrong. The coupler going bad sounded like what was going on, we took the washer apart and found the coupler in bits. We started taking more apart and also found that the cam agitator was in pieces. Ordered both parts from appliancepartspros.com, got the coupler first, replaced it and the washer now agitates! The first few uses smelled like burning rubber and squeaked a bit. But now no smell or squeak since the part settled in. Just wanna say we bought a whirlpool washer and dryer set used 10 years ago and washer just now gave out. This website saved us a ton of money without having to buy a new washer. I prefer older models anyway so hopefully replacing these parts will give us another 10 years or more.
