Causes For Water Heater Tripping The Breaker

A water heater repeatedly tripping the circuit breaker indicates a potentially hazardous issue requiring immediate attention. Electrical issues with the water heater can result in severe damage or harm if not diagnosed and fixed promptly and correctly.

Here are a few possible reasons that can cause the problem to occur, all of which require the assistance of a professional technician:

BROKEN HEATER

A fault within the water heater is one of the common reasons that can cause the unit to trip the breaker. Water heaters are susceptible to wear and tear over time and can create issues due to old age. Also, they can experience damage due to ongoing construction around them. A water heater installed incorrectly in the first place can also cause the breaker to trip repeatedly.

MALFUNCTIONING THERMOSTAT

A faulty or incorrectly installed thermostat is another common reason behind a water heater tripping the breaker. A thermostat is a vital part of an electric water heater system that regulates temperature. A standard electric water heater has two heating elements, each controlled by a thermostat, which ensures that only one of the two heating elements is on at a time. A malfunctioning thermostat can cause both the heating elements to run simultaneously, which causes the circuit to draw more electricity than what it can handle, causing the breaker to trip.

POOR WIRING OR FAULTY BREAKER

A short circuit in the internal wiring or a loose wire in the electric panel can also result in tripped circuit breakers. Such issues are challenging to diagnose, and it is best to seek professional assistance. Sometimes, the problems with the breaker itself can also result in continual tripping. A faulty, old, or worn-out circuit breaker can trip, even when the water heater operates correctly.

AN ISSUE WITH THE HEATING ELEMENT

As stated earlier, a water heater has two heating elements, one at the top and the other at the bottom, responsible for heating the water. When one or both of these heating elements break or burn out, it results in a split in the casing, exposing the electrical wires and making them touch the tank or water. It can result in a short circuit, causing the water heater to trip the breaker.

LEAKS

Water heater leaks can happen due to loose fittings or holes. Leaks in the water heater can cause the water to come in contact with the electrical components, resulting in a short circuit and a tripped breaker.

WHAT NOT TO DO WHEN A WATER HEATER TRIPS THE BREAKER

  • Never turn the breaker on repeatedly, as it can overheat the wires, resulting in a fire or failed breaker.
  • Never install a breaker with a higher amperage rating without upgrading the wiring.

SAFEGUARD THE WATER HEATER AND ELECTRICAL SYSTEM

Regardless of the cause behind a water heater tripping the breaker, it is best to call a trained and experienced water heater technician to look into the problem and recommend the best course of action. A professional can fix any underlying issues with the electric water heater safely and quickly.
