ES40R123-45D
Whirlpool ES40R123-45D Electric Tank Water Heater Repair
Most common issues on this model
- Reset button tripping
- Element gasket weeping
- Thermostat mounting bracket and contact
- Drain valve leaking after a flush
The ES40R123-45D is an electric storage water heater sold under the Whirlpool name, with two heating elements, adjustable thermostats and a temperature and pressure relief valve. It is the kind of tank often installed in a utility closet or garage in Houston homes.
When the reset button keeps tripping, we measure the elements and check the thermostats and wiring, because a shorted element or a loose connection can both cause it. A tank that gives lukewarm water gets the lower element and thermostat tested. If you see moisture, we trace it to the element gasket, the drain valve, the relief valve or the tank itself, because each has a very different repair.
The thermostat bracket can loosen, leaving the sensor away from the tank wall, so we check contact before replacing anything. We read the model and serial label to confirm the full number and match parts. You receive a written price first, and every repair comes with a 30-day workmanship warranty.

The reset button on my ES40R123-45D keeps tripping. Why?
A shorted element, a thermostat that fails to open or a loose wire can all trip it. We measure the elements and thermostats before replacing anything.
Water drips from the drain valve after I flushed the tank. Is that normal?
Not normally. Sediment can hold the valve open slightly. We clear it and replace the valve if it still leaks, which is a simple repair.
Can you tell where a leak is coming from?
Yes. We follow the moisture back to the gasket, valve, fitting or tank wall. A leak through the tank wall means replacement, and we say so before you spend anything.
