Question about Water Water Heaters
An E2 code is often an indicator of an electrical problem inside the water heater. The most common problem is with the inlet water temperature sensor. Often a reset will fix the problem. To achieve the reset unplug the unit. Open the unit being careful of fragile electrical wires. Next remove the computer board and then disconnect each plug in wire and reseat them one at a time. Reassemble the unit and plug it in. It should be in working condition, without the E2 code.
