The little cube means that the water pressure isn't good enough to fill the entire icemaker mold. Usually this means that the valve on your house is restricting the flow. The valve is usually a "saddle valve" which typically last 8-10 years before they begin to restrict the flow.
But the newest problem of the icemaker not even cycling has nothing to do with the lower water pressure other than it may have contributed to the icemaker failing since these icemaker strip out fairly easy if the icemaker gets jammed.
Make sure that the emitter boards are working properly and if so, you just need a new icemaker. If you open the door first, look at the red light to the right, is it flashing 2 times and then pausing over and over? If you shut the flap on the left side and make a clear path from right to left, does the light turn solid? If so then your emitter boards are working---if not you need to replace the emitter board.
Below is a link to the icemaker that you'll likely need as well as a video that shows you how to replace it.
