When put through a cycle, opened door to find half shriveled, undissolved detergent pack stuck to door and dirty dishes. Thought my daughter did something so I ran it again. Same issue.

When I turn it on it begins filling with water, but I'm not sure how far it's supposed to fill. In any event, no spray action ever happens and about 10 minutes in you'll hear the detergent door open and drop the pack, but no wash action. Unit drains correctly when I cancel the wash. Sometimes I can hear a "tick tok" sound coming from somewhere. Where should I start? Test motor for 120v?

Yes, It's a common problem with that style.
