After troubleshooting (looking for clogs, etc), we decided the drain pump needed replacing. After finding the helpful appliance parts pros video on this part, it looked like something we could do ourselves. Ordering was easy, the package arrived the next day, and the fix went relatively smoothly. Sure enough, the old pump had a piece of glass, that must have broke off a cup a while ago, jammed in the impeller. The old pump may have worked after removing the broken glass, but since we had it all torn apart we went ahead and put the new pump in (didn't want to be doing this again in the near future). Also used this opportunity to replace the pressurized water line (6 years old). We were back in business that night! Thanks.
