Check the Power Supply to the Water Heater
Before you can turn on your water heater, it is important to ensure that it is receiving power. Here are the steps to check the power supply:
1. Locate the Circuit Breaker
The first step is to locate the circuit breaker that controls the power supply to your water heater. In most homes, the circuit breaker panel is located in the basement or utility room. Look for a labeled breaker that corresponds to the water heater.
2. Inspect Fuses or Flip Breaker Off and On
Once you have located the breaker, inspect it for any blown fuses or tripped breakers. If you find a blown fuse, replace it with a new one of the same amperage. If you find a tripped breaker, flip it off and then back on again.
This can sometimes reset the breaker and restore power to the water heater.
3. Check for Power at the Unit
After inspecting the circuit breaker, it’s important to check for power at the water heater unit. Locate the electrical panel on the water heater and remove the cover. Using a multimeter, test for voltage at the terminals.
If there is no voltage, there may be an issue with the electrical wiring or the heating element.
It is always recommended to consult a professional if you are unsure or uncomfortable with handling electrical components. They have the expertise to safely troubleshoot and repair any issues with your water heater’s power supply.
Verify the Gas Valve or Heating Elements Are Working
Before turning on your water heater, it is important to verify that the gas valve or heating elements are working properly. This will ensure that your water heater is able to heat water efficiently and effectively.
Check Pilot Light on Gas Models
If you have a gas water heater, the first thing you need to do is check the pilot light. The pilot light is a small flame that should always be lit. If the pilot light is out, you will need to relight it in order for your water heater to function properly.
To relight the pilot light, follow these steps:
- Locate the pilot light assembly, which is usually found near the bottom of the water heater.
- Turn the gas control valve to the “off” position and wait for five minutes to allow any excess gas to dissipate.
- After five minutes, turn the gas control valve to the “pilot” position.
- Use a long lighter or match to ignite the pilot light. Keep the control valve depressed for about one minute after the pilot light is lit.
- Release the control valve and the pilot light should stay lit. If it doesn’t, repeat the process.
- Once the pilot light is lit, turn the gas control valve to the “on” position.
It is important to note that if you are unable to relight the pilot light or if it keeps going out, you may need to call a professional plumber to inspect and repair your water heater.
Inspect Heating Elements on Electric Models
If you have an electric water heater, you will need to inspect the heating elements. The heating elements are responsible for heating the water inside the tank. To inspect the heating elements, follow these steps:
- Turn off the power to the water heater at the circuit breaker.
- Remove the access panel on the side of the water heater to expose the heating elements.
- Use a multimeter to test the continuity of the heating elements. If there is no continuity, it means that the heating element is faulty and needs to be replaced.
- If the heating element is faulty, turn off the water supply to the water heater and drain the tank before replacing the heating element.
- Once the new heating element is installed, turn on the water supply and fill the tank before turning the power back on at the circuit breaker.
It is important to exercise caution when working with a water heater, especially when dealing with gas or electricity. If you are unsure or uncomfortable with any of the steps involved in verifying the gas valve or heating elements, it is always best to consult a professional plumber.
Examine the Water Supply Lines and Valves
Confirm Water Supply is Turned On
The first step in turning on your water heater is to ensure that the water supply is turned on. Before you proceed, make sure that the main water valve is fully open. This valve is typically located near the water meter or in the basement. If the valve is closed, turn it clockwise to open it.
It is essential to have a proper water supply for the water heater to function effectively.
Check for Kinks or Clogs in Lines
Once you have confirmed that the water supply is turned on, inspect the water supply lines for any kinks or clogs. Kinks in the lines can restrict the flow of water and affect the performance of your water heater. If you notice any kinks, gently straighten the line to ensure a smooth flow of water.
Additionally, it is important to check for any clogs in the lines. Over time, sediment or debris can accumulate and block the water flow. If you suspect a clog, you can use a pipe cleaner or a plumbing snake to clear the obstruction.
It is also a good idea to periodically flush your water heater to prevent sediment buildup and maintain its efficiency.

Adjust the Thermostat Settings
One of the key steps in turning on your water heater is adjusting the thermostat settings. This ensures that the water temperature is set to your desired level of comfort. Here are a couple of subheadings to guide you through this process:
Raise the Temperature Setting
To raise the temperature setting on your water heater, locate the thermostat dial. It is usually found on the front or side of the unit. Turn the dial clockwise to increase the temperature. Keep in mind that the optimal temperature for most households is around 120 degrees Fahrenheit (49 degrees Celsius).
This temperature strikes a balance between comfort and energy efficiency. By raising the temperature, you’ll be able to enjoy hotter water for activities like showering or dishwashing.
Reset High Limit Controls
High limit controls are safety features built into water heaters to prevent overheating. In rare cases, these controls may trip and shut off the heater. If you find that your water heater is not producing hot water despite being turned on, it’s possible that the high limit controls need to be reset.
To do this, locate the reset button on the control panel or thermostat. Press and hold the button for a few seconds until you hear a click. This should reset the controls and allow your water heater to function properly again.
Remember, it’s important to follow the manufacturer’s instructions and safety guidelines when adjusting the thermostat settings or resetting high limit controls on your water heater. If you’re unsure about any step, consult the owner’s manual or contact a professional plumber for assistance.
