there is no such button on the ice maker neither on the side nor the top
I disagree but lets try it another way _ close the freezer door and press the two top buttons left top and right top hold them in until the display flashes and then tell me if there is anything displayed before the temperatures reappear. Secondly have you got chilled water coming through ok?
nothing displayed and yes chilled water is coming through ok
OK if you press the ice button/lever can you hear the motor running ?
