Why is my water heater tripping my circuit breaker?
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.
What to do if your hot water heater has tripped?
If the breaker has tripped, switch it off, then switch it back on again. If the heater’s breaker did not trip (it is still on), try to reset the high-temperature limit on the heater: Turn off the breaker to the water heater’s circuit in the service panel. Remove the access panel for the upper heating element on the water heater.
What happens when an electric water heater goes bad?
When they go bad they sometimes get stuck in the on position. This causes the heating element, or both heating elements, to remain on and continuously heat the water. If the water heater has two elements, as most electric water heaters do, both elements remaining on at the same time can overload the circuit.
How many heating elements are in an electric water heater?
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.

How does an electric water heater heat water?
As we mentioned above, electric water heaters use two “elements” that heat the water. These elements are basically metal loops inside the tank that house electric wires. As current runs through these wires, the elements heat up and warm the water.
What’s the reset button on an electric water heater?
First off, your electric water heater can actually “trip” 2 different safety features:The reset button: a red button located on the water heater itself (just above the thermostat) that trips when the water temperature exceeds 180 F. The reset button is sometimes referred to as the &quo
What does eco tripping on electric water heater do?
The switch is designed to cut off the energy to the heating elements (and stop further water heating) of the electric water heater, in a case of the high water temperatures (150 F – 180 F). The ECO tripping protects you from getting scalded or burned when using hot water.
Why does my Rheem water heater keep tripping?
During the abnormal operation, the plate which is under the button, as seen on the Rheem electric water heater, will change its shape pushing the pin out, making the ECO trip. In such a case, the voltmeter will measure no current running between terminals and to the heating elements.
Why is my circuit breaker tripping on my water heater?
If you have aluminum wiring that runs from your water heater back to the electrical panel, it could be triggering electrical problems that eventually lead to the circuit breaker tripping. Here’s why: that aluminum wire has to connect to your water heater’s wiring-which happens to be copper (not aluminum).
Can a circuit breaker be tripped when there is no power?
It is a rare occurrence, which is one reason why a situation where there is no power and the circuit breaker is not tripped can be puzzling at first. A circuit breaker, the connecting wire and appliance, however, are all components of a simple circuit that you can troubleshoot with a standard voltage meter.
Can a fried eco switch cause a water heater to overheat?
A fried ECO switch will need to be replaced, but on the bright side, this problem alone can’t overheat your water. If your thermostats, heating elements, and ECO are all operating properly, it’s possible that a loose wiring connection could be producing another source of heat inside your water heater.
What to do if your hot water heater keeps tripping?
A simple continuity reading through the thermostat using a digital multimeter will confirm this as being the problem. Turn off the power to the water heater at the service panel and disconnect the wires from the thermostat. Set the meter’s function switch to its R X 1 scale and place the meter’s test probes on the thermostat’s terminals.
What does it mean when your hot water heater resets?
Related Articles. The hot water heater reset is actually a high limit safety thermostat switch that disconnects the power to the water heater if the water exceeds a preset temperature. The temperature sensing button of the reset is in direct contact with the metal tank and senses water temperature through conduction.
Why does my Water Heater get Too Hot?
When the upper limit switch trips it is often an indication that something else has gone wrong with the heater. The reset button trips because the water heater got too hot. The only reason that a water heater will get too hot is because one of the thermostats got stuck.
What causes a breaker to be tripped by a hot water heater?
Breaker Breaker. There are three possible explanations for a breaker being tripped by a hot water heater: water dripping on the electrical lines, a problem with the unit’s thermostat or a problem with the breaker.
Why does my water heater keep Tripping the limit switch?
The most likely cause of the limit switch tripping is a bad thermostat. Water heaters with two elements have two thermostats: one for each element. The thermostats communicate with each other to ensure that only one element is being heated at a time. When they go bad they sometimes get stuck in the on position.
What to do when your water heater is tripping its reset button?
There are a few types of problems that can cause your water heater to overheat the water in the tank, and when that happens, the emergency cut off (ECO) kicks in to shut down the appliance completely. To reset it, you’ll need to press the red reset button on the ECO, which is usually attached to the upper thermostat.
What makes an electric water heater a bad thermostat?
A bad thermostat Electric water heaters have 2 thermostats-an “upper” thermostat and a “lower” thermostat. The upper thermostat controls the upper heating element and the lower thermostat controls the lower heating element.
First off, your electric water heater can actually “trip” 2 different safety features:The reset button: a red button located on the water heater itself (just above the thermostat) that trips when the water temperature exceeds 180 F. The reset button is sometimes referred to as the &quo …
What can cause a circuit breaker to fail?
A circuit breaker can fail due to: 1 Age 2 Continuous tripping 3 Corrosion due to humidity/chemicals in the air
What to do if your hot water heater flips?
In this case, the thermostat should be replaced. It may be worthwhile to replace the heating element at the same time. A leak that allows water to come in contact with any of the electric components is dangerous and can cause the breaker to flip.
Why does my water heater keep turning off?
Supplied through a circuit breaker or fuse, the electrical circuit must be operational for the process to begin. The thermostat controls the desired temperature setting by continuously cycling the power on and off. The last of the three-part system is the heating element. The heating element provides a source of heat to the water.
What happens when a heating element fails on a water heater?
Usually, when a heating element fails it stops heating and water is colder than normal. If this is the case, then the heating element is open internally and won’t cause any damage. Unfortunately, this isn’t always the case. Sometimes, the casing on the heating element can split.
What does it mean when your breaker switch is hot?
Practically speaking, however, a hot breaker switch is one that is noticeably hot to the touch. Electrical resistance increases at points of loose connection and that generates heat. This means that your overheated breaker may simply be loose.
Why is the reset button on my water heater not working?
Just like all parts of the water heater, the reset button will eventually suffer from wear and tear. This can cause it to perform less effectively and continually trip regardless of the temperature of the water in the tank. The reset button is actually part of your upper thermostat.
What should I do if my HW breaker keeps tripping?
I suggest you call an electrician before your home burns down. HWS should always be on its own circuit for a start. Sounds like someone has wired it to a power circuit, which are normally 16/20 amp. Of course it was tripping, your circuit is being overloaded. Now you have removed the protection by upping the CB to 30amp. Dumb thing to do.
Why is my circuit breaker hot to the touch?
Most homeowners probably wouldn’t think to break out the thermometer when checking out their circuit breaker. In most cases, it’s safe to say that if your circuit breaker is hot to the touch, something has gone awry within its system. Let’s take a look at some of the reasons that this may be happening.
What should the temperature of a circuit breaker be?
Generally, units should not exceed an ambient temperature greater than 90º F, and the knob temperature should not exceed 185º F. Knobs are expected to reach higher temperatures since most of them are created from plastic. Most homeowners probably wouldn’t think to break out the thermometer when checking out their circuit breaker.
What would cause an electric water heater to trip the breaker?

Why does a new hot water heater cut off breaker?
The heating element provides a source of heat to the water. A failure in any part of this system can cause a water heater to shut off. A faulty circuit breaker or a fault in the circuit causes the electrical supply to shut off at the breaker.
What causes a hot water heater to keep kicking off?
Your gas valve is what delivers natural gas directly to your water heater. Gas from this valve lights your pilot light and eventually lights the gas burners that heat your water. But if this valve or its inner elements are damaged, it can’t deliver enough gas to your water heater, causing it to shut on and off.
What causes a circuit breaker to trip when overloaded?
Usually when a circuit is overloaded, the breaker takes 10-30 seconds to trip due to a time delay feature internal to the breaker. A short circuit is a more serious reason for a breaker tripping.
Why does my AC blower trip the breaker?
This causes the blower to draw more electricity and trip the breaker. Solution: Change the air filter. Your AC system has an inside unit and an outside unit. The inside unit absorbs heat from your air using refrigerant. That refrigerant flows to the outside unit to disperse the heat.
What does a ground fault breaker on an RV do?
The RV has fuses and breakers that shut the electricity off if any problems happen. In addition to the breakers and fuses for the AC and DC systems, there are Ground Fault Circuit Breakers (GFCBs) or Ground Fault Indicators (GFIs) in most 110-volt electrical receptacles that shut off the power to appliances plugged in if a circuit or wire shorts.
What causes a water heater to trip a circuit breaker?
