OK, this is a real weird one (at least to me).

Dishwasher won't drain. I've already pulled it apart. The drain pump looked and felt OK, and the impeller on the recirculation pump looked and felt OK as well. So I put everything back together (managing to forget to reconnect power to the recirculation pump motor in the process) and re-installed it to see if the recirculating pump was working or not. Put on rinse cycle, let it fill, noticed it wasn't making rinse noises, remembered about the connector. I hit cancel and... it drained!

After getting the connector put back on the recirculating motor, I reinstalled again and tried the rinse cycle again (I really thought I had lucked out). After checking to make sure it was spraying water around the tub after filling I hit cancel again. Only, no draining occurred. :/

So now I'm at a loss at what to check. Any ideas?
