What happens if you increase the size of a breaker?
Now the breaker will let additional electricity flow to the circuit, which can overheat wires and cause a fire.
How does a bad thermostat work?
Bad thermostat. Each heating element is controlled by a thermostat; both thermostats “talk” to each other to ensure that only one heating element is on at a time. Here’s how that works: On an electric water heater, only one heating element is on at a time. Photo source.
What happens when heating elements fail?
Usually, when the heating elements fail, they simply burn out and the only way you’ll notice is that the water isn’t as hot as it once was. But sometimes, the heating element casing can split and expose the electrical components directly to the water or tank.
What is a burned out heating element?
Burnt out heating element. The heating element is the part of your water heater that heats the water. Most electric water heaters have 2 heating elements: one on top and one on the bottom. Diagram of an electric water heater with 2 heating elements. Photo source.
Thermostat Issues
When your water heater thermostat is faulty or improperly installed, it loses ‘communication’ with the breaker, which can cause an electrical imbalance of power. Rather than regulating the electricity to the heating elements, this imbalance of excess electricity feeds into the circuit breaker instead.
Burnt Heating Elements
Sometimes the element that heats the water in the heater can be the source of the issue. If the heating element breaks or burns out, this can cause a spit in parts of the heater, exposing wires and electrical components to direct contact with water.
Faulty Breaker or Wiring
The issue may not even have to do with your water heater. Your circuit breaker could be worn and faulty from age. Or there could be a loose wire in the electrical panel, causing the system to short circuit. In either case, it’s the breaker causing the issue, and not your water heater.
What Can You Do?
The first and most important thing to remember is to not continue flipping the breaker back on after it shorts out. Doing this repeated runs the risk of overheating wires and causing a fire, which will be significantly worse than a broken water heater.
1. A Faulty Thermostat
Every water heater has a temperature control switch limited to 180° Fahrenheit to prevent the water from overheating and scalding your skin.
2. Malfunctioning Heating Element
The pair of heating elements are responsible for warming up your water, and if either of them fails, they can cause a short circuit.
3. Leaky Water Lines
Water line leaks can also cause the breaker to trip. If your water heater pipes are old and withered, they’ll naturally be weakened over the years, and you might develop leaks.
4. Faulty Electrical Connections
If the constituting parts of the water heating appliance are in perfect condition, then the problem is probably with the electrical lining.
5. Inspect the Breaker
If everything is in perfect shape, yet the breaker is tripping repeatedly, then the problem lies in the breaker itself. Sometimes breakers will wear out after long-term use and trip the slightest exposure to electricity.
What happens if water goes through the main breaker?
This is a very dangerous scenario that could lead to serious electrical shock or fire. Water connecting with the electrical system usually trips the main breaker automatically. If it doesn’t, shut the breaker off immediately and locate the source of the leak.
How does a water heater work?
The water heater provides hot water to the entire household for bathing and household cleaning. It does this by siphoning water through a dip tube and heating it inside the water tank. Once heated, the water rises and moves through the heat-out pipe into the home’s water sources.
What does a 120 volt water heater mean?
Use the multimeter to test the points where the wires attach to the element. A 120-volt reading may mean a cracked casing or corrosion, while zero volts means the element has shorted.
What happens if a thermostat goes bad?
If a thermostat goes bad, the element may fail to shut off and possibly run concurrently with the other element. This causes the heater to exceed the 180-degree temperature and draw more electricity than required. This will subsequently overload the circuit breaker and trip the limit switch, breaker, or both.
What happens if you check out your heater?
You’ll have to check the heater’s wiring for burned connections, damaged wire, or signs of electrical arcs. You will likely smell smoke before you find any visual damage.
What is the difference between gas and electric water heaters?

3. Extension cord
Since space heaters are a household item, most people do not give a second thought to plugging them into a extension cord to locate them to their most convenient spot.
4. The breaker itself
Breakers weaken and go out. Hello this is usually not the case, it is not impossible that the breaker itself needs to be switched out. The easiest way to tell if this is the case or not is the plug the heater into another outlet in another room, and see if you’re still blowing the breaker.
What Can Cause a Thermal Switch to Trip?
A variety of things can cause a water heater’s thermal switch to trip. If you can’t diagnose the problem on your own, you should get help from an experienced and skilled plumber.
The Heating Element Is Burnt Out
A system’s heating elements are what heat the water inside, and if one of your heating elements experiences a short, then it’s likely the metal casing that covers the element is cracked. If this is the case, then it’s also likely that live wires are exposed to water.
Is the System Set Up to Fail?
First, you must check the draft hood which is located towards the top of the water heater. Make sure there are no obstructions, and also make sure there’s nothing on top of the appliance.
