Failure to adhere to this requirement directly impacts the lifespan of the heating elements, leading to premature failure. Initiating the water heater without confirming element submersion introduces the risk of overheating. As heating elements generate substantial heat, this heat must be dissipated into the surrounding water. Absence of adequate water coverage inhibits heat dissipation, causing the element to reach excessive temperatures and subsequently fail.
Consider the practical scenario of replacing a faulty heating element in an electric water heater. Upon installation of the new element, the tank is not completely filled before the circuit breaker is engaged. Within minutes, the exposed portion of the heating element overheats, causing it to burn out. Conversely, a water heater properly filled and purged of air ensures the element remains submerged. This full submersion allows efficient heat transfer to the water, maintaining the element within its operational temperature range and extending its longevity. Ensuring complete submersion is a critical control that, when executed correctly, significantly extends component life.
In conclusion, the condition of element submersion is not merely a precautionary measure but a fundamental requirement for safe and efficient operation of an electric water heater. Understanding the necessity of complete water coverage prevents avoidable component failure and maximizes the operational lifespan of the appliance. The process of activating an electric water heater inherently necessitates confirmation of element submersion as a prerequisite for power engagement, therefore protecting the integrity of the electrical components and increasing overall efficiency.

If the voltage is wrong, the heater may be unable to turn on.
For instance, consider a scenario where an electric water heater, designed for 240V operation, is connected to a 208V circuit. While the appliance may initially appear to function, the reduced voltage forces the heating elements to draw higher amperage to compensate for the power deficit. This elevated current can lead to premature element failure, overheating of wiring connections, and eventual breakdown of the appliance. Conversely, an over-voltage situation, such as a surge or misconfiguration, can instantaneously damage the sensitive electronic components within the water heater’s control system. Voltage verification helps reduce unexpected component failures.
In conclusion, voltage verification is not merely a precautionary measure, but a fundamental requirement for the safe and reliable operation of an electric water heater. This procedure confirms system integrity, reduces safety risks, and helps to extend the lifespan of the appliance. This process should occur prior to any operation of the electric heater, preventing unforeseen electrical risks or damages to electrical elements that operate the appliance.
