    A:  have changed elements, twice, control box, Its total junk, save your money and buy another brand. There customer service reps are no help and are nasty, the product should be taken off the market. ecosmart should fire there service reps.

      A:  The water heater is in my opinion junk. I have replaced the control board not once but twice. I reused the first control board and it worked perfectly then it completely died. In my opinion it's not worth fixing you would have to replace everything in it the water temp sensors the flow sensor and the heating elements. Just replace it with a better unit. Just my opinion

        Item arrived on time and in appropriate condition. Be advised, if you have an older EcoSmart unit, this is the upgraded version of the board. There are two sets of terminals for the thermistors (as opposed to one set on the old board). The thermistors needed to be plugged into the set I didn't expect.

        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.
