Yeah the steps should be online somewhere. I remember having to do this as part of my troubleshooting. I think it involved manually moving the lever that gets pushed in when the ice tray is fully inserted. I think I had to press it in, then release it, 3x or something like that. Those steps would manually kick off the steps of pushing out the formed ice and then opening the valve to fill the ice mold w water.

If you watch what happens you can see if 1) the ice is being ejected from the mold properly, and 2) if the mold is being refilled w water.

In my case, the valve was working properly, but the fill tube (the portion of the tubing that's located on the inside of the freezer section) was frozen.
