A: I replaced my control board and it lasted about two months and started not heating the water the display would stay on but the water would not be the correct temperature. In my opinion the eco smart tank less water heater is not worth the hassle of installation choose another brand
A: Yes. But check the fuse on the board first. You can check the fuse with a simple continuity check.
