Learn Why Your Water Heater Keeps Turning Off

When your water heater keeps going off, it can ruin your normal routine and cause inconveniences. What’s more, it can lead to safety issues depending on the underlying problem. For instance, a faulty thermostat could lead to overheating and scalding. It is important to get the issue figured out as soon as possible and restore the appliance to good working order.

Here at Mr. Rooter Plumbing, we are the go-to plumbing company for all things to do with water heaters, including water heater replacement. Let’s look at some of the reasons why a water heater may keep turning off.

  • Malfunctioning Heating Element

The heating element is the heart of a water heater. It is located at the bottom of the tank and heats water inside the tank when you turn it on. If the heating element is worn out, corroded, or faulty, your water heater will automatically shut down. When the heating element burns out, you won’t get any hot water, and the circuit breaker may trip every time your water heater kicks on. If you suspect a faulty heating element, it’s advisable to call a professional plumber to troubleshoot your water heater and fix the unit.

  • Faulty Thermostat

A thermostat is an important component of a water heater, responsible for maintaining the desired water temperature. According to most plumbers, the best water heater temperature setting is between 120 and 140°F. If the thermostat malfunctions, your water heater will overheat the water and cause the appliance to turn off. You’ll know there’s a problem with your water heater thermostat if you experience fluctuating water temperature. The best way to know if your thermostat is the reason your water heater keeps turning off is to have it inspected by an experienced plumbing service.

  • Overloaded Circuit

The primary function of a circuit breaker is to monitor the circuit and interrupt electricity flow upon detecting a short circuit or an overcurrent. In other words, it acts when a fault is detected and cuts off electricity supply to the water heater. If the circuit serving your water heater is overloaded, you’ll experience a tripped circuit breaker, thereby turning off the heater. However, this is not the only reason why the circuit breaker may trip—wiring issues and a faulty heating element can also cause this problem. You can try unplugging some of the appliances connected to the same circuit as the water heater and reset the breaker. If the breaker still trips, it’s best to call an experienced plumbing service or an electrician to diagnose and fix the underlying issue.

  • Faulty Pressure Relief Valve

A temperature and pressure relief valve safeguards your water heater against both high pressure and temperature buildup within the hot water tank. The valve opens when either the temperature or pressure limits are exceeded to ensure safe operation. If the T&P valve malfunctions, it won’t be able to discharge built-up pressure within the tank or release scalding hot water when the temperature limit is reached. In a situation where the T&P valve has malfunctioned, a water heater will shut down to prevent catastrophic failure. It is advisable to have a professional plumber inspect your T&P valve on a regular basis to ensure the valve is in peak condition.
