Just bought range from the Brick. First time used and indelible flaw appeared on the front  left burner (boiled water!). Looks like a deep, under the surface (glass NOT ceramic) alteration on the element. Inaccessible from the top, unaffected by cleaning of any kind indicated in the user guide. A technician or agent should come inspect the unit. Very disappointed. I will publish a documented negative review on the net   
if nothing is done.
