Check that you have enabled the main power button.  As it is on very back/bottom of the system, we've had some customers overlook it..  You'll want to switch that to the On position ("|" symbol not the "O" which is off).  As a note on the button.  If you had already pushed the side button, when you turn the back main power switch on, it starts brewing immediately.  That side is an "on-only" thermally-reset switch that is designed to auto-shut-off, following the brew.  It isn't designed to be manually turned off.  So, I would load your water and coffee first before turning the main power on.  It will then begin your first coffee brew right away.   After that, you just leave the main power on and the the simple procedure would be to add the desired amount of water to the reservoir, place the Ecopour on the arm, and then hit the side button to start the brew.
