It's a pretty simple system. If you can hear the pump running than it's probably fine. As far as I know the system consists of the pump, some basic piping to each head, and then there are poorly designed passages that clog up, as I'm sure you read all about already. There is also the electrical half, but if the pump is running then you can rule that out. The only thing other than CBU is maybe a break in the plastic tube from the pump that runs to the metal tube..
