My rinse aid quit working a few months back. I am trying to find out if there is a wax motor that dispenses the agent or if it is mechanically dispensed through the actuator arm. I opened the front cover and didn't see any motor. I had the inside cover off a few years back and don't remember seeing one on that side either. I also would like to know where the rinse agent is released at inside the dishwasher. I don't know if I have a clogged port or what. I have read where some models the agent comes out the cap. I don't think my model is like this as my cap screws in and it has a bulb at the end that sits in the agent. Any help is greatly appreciated.

Thank you Gene. It worked for me.
