Rondomatic 400 Automatic Fish Feeder (not fully working)

This is a Grasslin Rondomatic 400 automatic fish feeder. The nice part about this feeder is the trays can hold dry fish food or even liquid, such as water having brine shrimp. By positioning the pegs you can cause one of the 28 trays to dump whenever you like in a 24-hour period. **Unfortunately**, the feeder stopped dumping the trays even though the clock portion still works. I think this is an assembly problem. All of the parts are present, including the tiny spring shown in the last picture. There are a few examples online showing assembly, but I just could not get it fully working again. This unit would be great if you just need parts, or if you want to try to get the trays to dump again.
