Brand New Nespresso Essenza just stopped working..

Question

I purchased a new Nespresso Autmatica yesterday, it worked perfectly for the first two cups of coffee and this morning it refuses to produce any coffee. The machine turns on, goes through the usual routine of flashing lights etc then they stop as if to show it's ready. When I place a capsule in and press the cup sign nothing happens, it flashes for a few seconds and then stops. No noise nothing...... HELP?????
