Thanks so much for the answers guys. I was able to take off the front cover, unscrew/drain the coin trap and find a disgusting sock in there, completely clogging it! Cancelled the appliance repair guy just in time. Catching the water as it comes out of that trap is tricky, and I missed a lot of it. There's probably a better way, but I just stuck folded towels under the plug as I unscrewed it.
