Whirlpool ES50R123-45D Electric Water Heater

Model # ES50R123-45D

Electric heaters recover more slowly than gas, so a large household draining the tank has to wait. That is capacity rather than a fault, and it is worth confirming before a service call.

Anode rod replacement is the single best way to extend tank life in hard water, and it is a routine technician job. Owners can flush sediment if the drain valve cooperates, but a seized valve is best left rather than forced.

FAQ

Whirlpool ES50R123-45D Electric Water Heater FAQ

On electric, reheating a large tank takes a few hours. If your household regularly empties it, tank size rather than a fault is the limiting factor.

It is a sacrificial rod that corrodes so the tank does not. Changing it periodically is the cheapest way to extend tank life.
