Tripping the electrical switch presuming a faulty element,how do i change it

It's possible that the sequencer needs to be replaced, as it's responsible for turning on and off the different heating elements in a certain sequence. However, it's also possible that the issue could be with another component, such as the high limit switch or a faulty heating element. It would be best to have a qualified technician diagnose and troubleshoot the issue to determine the root cause and recommend the appropriate solution.

Why Does My Electric Water Heater Reset Button Keep Tripping? So the red reset button on your electric water heater keeps popping out and needing to be reset.
Here's the most likely problem: The water in your water heater is getting too hot.
When the water temperature in your water heater exceeds 180°, the red reset button (also known as the high-limit switch) trips. This tripping protects you from getting scalded or burned when using hot water in your home.
OK, but then what's causing the water in your water heater to get so hot? The most likely cause is a bad thermostat.
How a bad thermostat causes your water heater reset button to trip Electric water heaters have a lower and upper thermostat-one for each heating element.
The thermostats are responsible for controlling the heating elements. When the water has cooled off, the thermostats kick on the heating elements to heat the water. And once the water has reached your desired temperature, the thermostats shut off the heating element.
(This is very similar to the way your heating and air conditioning thermostat controls your home HVAC system.)
But these thermostats can go bad. When they do, they sometimes get stuck in the "on" position. This means that that the heating element continues to heat your water, eventually causing the high-limit switch to trip.
The fix: The bad thermostat needs to be replaced. A plumber can use a multimeter to test the thermostats and find out which one is bad.
Other problems that can cause your high-limit switch to trip While a bad thermostat is the most common reason your water heater's reset button may trip, it's not the only one. Other common causes include:

• A shorted heating element-It may be that the thermostat is working just fine and shutting off the heating element. But a short in the element is causing it to continue to heat your water.
• Loose wiring-A loose wire in the water heater can generate heat that can cause the high-limit switch to trip.
• Bad high-limit switch-The switch itself may be malfunctioning and tripping when it shouldn't be.

Always helps if you give more info. BUT Going on what you say, I can only assume electrical heater, With faulty element. Replace element.

Yes. It seems the element is shorted/touching the tank. If you have a volt ohm meter VOM, disconnect the power to the water heater, and remove the wires from each heating element. Touch one VOM probe to one side of the element and the other to the tank. There should be no reading to the tank. The element that has a reading to the tank is the shorted element.

unless it is solar it will have either a gas element for gas heaters or electric element for electric heaters. presumming it is electric, the element is an immersable element mounted in the bottom of the tank. when the electrical cover is removed you will see the 4 bolts that hold it in place.

the element is shorted out causing this issue.
I have had that happen to me before.
or there is a water leak dripping down on it and causing it to trip the reset switch.

It sounds like you have things pretty well covered. I would change reset and if it continues to trip breaker I would check wiring very carefully where it enters top of water heater. Check for any nicks or bare spots on wiring insulation. Other than that about all I can think of is to change breaker. Sometimes they do get weak and trip to easily. Hope this helps. Thanks

It will be on back side of water heater, follow hydro wires into metal or plastic cover. (shut breaker off before proceeding) remove that cover and you will find element. Double check thermostat and ECO for tripped reset switch (little button in center of it) while cover is off as well, before going through trouble of changing element.

Test elements for short to ground.
Element that is shorted in center might not trip breaker.
Because thermostat only turns off one leg of 240V circuit, the element will continue heating using 120v to ground:

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

Sounds like you have a faulty thermostat.  This is the unit that detects the water temperature, and if it is not where it is set, will kick the switch to allow electricity to flow to the elements you replaced. The thermostats are relatively cheap and if you have the knowledge to change the elements, changing these thermostats should not be a problem.
