Do you find yourself standing at the sink, waiting for hot water to wash your hands, only to realize that your water heater has turned off? If you’re facing this frustrating issue, there are several potential causes that could be leading to your water heater shutting off. While you can try some troubleshooting on your own, it’s always a good idea to consult with a plumber to confirm your findings and get professional assistance in fixing the problem.

Determining the Type of Water Heater
To begin your troubleshooting process, it’s important to first determine whether you have a gas or an electric water heater. An electric water heater will be plugged into an outlet, while a gas water heater will have intake and exhaust pipes for gas. Understanding what type of water heater you have will help you pinpoint the potential issues.
Gas Water Heater Shutting Off
Gas water heaters commonly shut off due to problems with the pilot light, thermocouple, or gas supply.
1. Pilot Light Burner
If the pilot light on your gas water heater goes out, the entire unit will shut down. You can check if the pilot light is still lit by inspecting its compartment. In many cases, the pilot light goes out due to dirt and dust build-up, restricting airflow and causing it to extinguish. Instead of simply relighting the pilot light, it’s best to call a plumber to clean out any accumulated dust and debris.
2. Thermocouple
Another potential reason for the pilot light going out is a worn-out thermocouple. Fortunately, replacing the thermocouple is a relatively simple and affordable fix that can be done by a plumber.
If your gas water heater doesn’t seem to have any issues with the pilot light or thermocouple, a gas supply problem might be to blame. It’s essential to leave this problem to the professionals, as dealing with gas-related matters can be hazardous.
Electric Water Heater Shutting Off
Electric water heaters come with their own set of unique problems that can cause them to shut off unexpectedly.
1. Water Temperature Too High
Have you recently adjusted the temperature settings on your hot water heater? If so, setting it too high could trigger the safety shut-off mechanism. Most water heaters have a limit of 180 degrees Fahrenheit to prevent scalding. Try turning down the temperature slightly (especially if you recently increased it) to see if that resolves the issue.
In some cases, if the temperature is excessively high and you haven’t made any adjustments, the heating element might be continuously running, leading to overheating. This could be a result of various underlying issues that require professional attention from a plumber.
2. Other Electrical Problems
It’s possible that a component of your electric water heater or a connected device, such as a smart thermostat, is malfunctioning and causing the system to shut off. The heating coil, thermostat, thermometer, or other parts of the system could be contributing to the problem. To accurately diagnose and address these issues, it’s best to consult with a plumber.
Remember, there are numerous other potential reasons why your water heater keeps turning off. Ignoring this problem can lead to further damage to the heater or even your home, so it’s crucial to address the issue promptly.
