Answer This Question

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

        Circuit Board Replacement
        Circuit board arrived in two days and, with Eco technical support, I was able to configure it for my model. The tank now works as it should. Eco technical support was very helpful.

            It was almost a straight swap out. There are a set of 4 plugs where the OEM had only 2. Instructions say to use the inner set for ECO 36. And, it launched with no problem

            We have been very unhappy with this water heater. The replacement part did not work either.
