However, it’s important to note that there could be other underlying problems causing the lack of hot water, so it’s always a good idea to consult a professional if the issue persists.
Discolored or smelly water
When you notice that the hot water coming out of your faucets is discolored or has a foul odor, it’s a sign that your water heater needs attention. This could be due to sediment buildup or a reaction between the anode rod and the water.
Resetting the water heater can help flush out any accumulated sediment and improve water quality.
Temperature fluctuation
If you experience inconsistent water temperatures, with the water suddenly becoming too hot or too cold, it could be a sign that your water heater needs to be reset. Fluctuating temperatures can be caused by a malfunctioning thermostat or a faulty heating element.
Resetting the water heater can help recalibrate the thermostat and resolve the issue.
Error codes
Modern water heaters often come equipped with advanced features and digital displays that show error codes when something goes wrong. If your water heater displays an error code, it’s an indication that a reset might be necessary.
However, it’s recommended to consult the manufacturer’s manual or contact a professional to understand the specific error code and the appropriate steps to resolve it.
Remember, while resetting your water heater can often solve common issues, it’s important to exercise caution and follow the manufacturer’s instructions. If you’re unsure about the reset process or if the problem persists after resetting, it’s always best to seek professional help to avoid any further damage.
How to Reset an Electric Water Heater
Resetting an electric water heater is a simple process that can be done in a few steps. By following this step-by-step guide, you can ensure that your water heater is functioning properly and providing hot water efficiently. Here’s how to reset an electric water heater:

After draining the tank, inspect the heating elements and thermostats. These components are responsible for heating the water in the tank. Check for any signs of damage or corrosion. If you notice any issues, it’s recommended to replace them.
Make sure to follow the manufacturer’s instructions when doing so.
4. Refill the tank
Once you’ve inspected the heating elements and thermostats, it’s time to refill the tank. Close the drain valve and remove the garden hose. Turn on a hot water faucet in your home to allow air to escape from the tank as it fills. Open the water supply valve to refill the tank.
Once the tank is full, you can close the hot water faucet.
5. Restore power and confirm reset
The final step is to restore power to the water heater. Go back to the breaker box and flip the breaker for the water heater to the “on” position. This will restore power to the heater. Wait for the water in the tank to heat up, which can take a couple of hours.
Once the water is hot, test the hot water faucet in your home to confirm that the water heater has been successfully reset and is providing hot water.
Remember, if you encounter any difficulties or are unsure about any step in the process, it’s always best to consult a professional plumber. They have the expertise and knowledge to safely reset your electric water heater and address any underlying issues.
Resetting a Gas Water Heater

1. Shut off the gas
The first step in resetting a gas water heater is to shut off the gas supply. Locate the gas valve on the water heater and turn it to the “off” position. This will ensure your safety while working on the heater.
2. Drain the tank
Next, you’ll need to drain the tank to remove any excess water and sediment. Attach a hose to the drain valve at the bottom of the tank and place the other end in a suitable drainage area. Open the valve and allow the water to completely drain out.
3. Check pilot light and thermocouple
After draining the tank, it’s important to check the pilot light and thermocouple. These components are crucial for the proper functioning of the water heater. Ensure that the pilot light is lit and the thermocouple is securely connected. If either is faulty, they may need to be replaced.
