If a plumber is called to repair an electric hot water heater, what is the probable solution?

When repairing an electric hot water heater, the first step a plumber should take is to check for power. Electric hot water heaters rely on electricity to function properly. If the heater isn't producing hot water, there may be an issue with the electric supply to the unit, such as a tripped breaker or a blown fuse. Ensuring that the unit has power and is operational is crucial before moving on to other potential causes of the problem.

While checking for leaks, replacing the heating element, or flushing the tank are all valid steps within the broader context of troubleshooting hot water heater issues, they may not address the immediate concern if the unit is not receiving electricity. Without verifying the power supply first, any subsequent repairs might not resolve the issue at hand. This is why confirming that the heater is powered on should be prioritized in the troubleshooting process.
