There’s nothing quite as frustrating as stepping into the shower only to be greeted by a blast of cold water. When your water heater stops working, it can throw a wrench in your entire day. But before you panic and call for help, there are a few things you can try on your own to get your water heater back in working order. Here’s a step-by-step guide on what to do when your water heater isn’t working.
One of the first things you might be concerned about when your water heater isn’t working is the potential cost to repair it. Repair costs can vary depending on the issue, but understanding what factors into the cost can help you prepare.

1. Check the Power Supply
The first thing you should do when your water heater isn’t working is to check the power supply. If you have an electric water heater, make sure it’s plugged in and that the circuit breaker hasn’t tripped. Sometimes, a simple reset of the breaker can solve the problem. If the breaker has tripped, reset it and see if the water heater starts working again.
For gas water heaters, check that the pilot light is on. The pilot light is responsible for igniting the gas that heats the water. If the pilot light is out, follow the manufacturer’s instructions to relight it. If you’re not comfortable doing this yourself, it’s best to call a professional.
2. Inspect the Thermostat
The thermostat controls the temperature of the water in your heater, and if it’s not set correctly, your water might not be getting hot enough—or it might be too hot. Most water heaters have a thermostat dial on the front, which is usually set between 120°F and 140°F. If the temperature is set too low, try turning it up a bit and see if that solves the problem.
If adjusting the thermostat doesn’t help, it could be faulty and in need of replacement. This is a more complex repair that might require a professional’s help.
3. Look for Leaks
Leaks around the water heater are a sign of trouble and can lead to significant damage if not addressed quickly. Check around the base of the water heater and look for any pooling water. Also, inspect the pipes and connections leading to and from the water heater.
If you find a leak, it’s important to determine where it’s coming from. Some leaks can be fixed with a simple tightening of a connection, while others may require more extensive repairs. If the tank itself is leaking, it may be time for a replacement, as this typically indicates that the unit is failing.
4. Flush the Tank
Over time, sediment can build up at the bottom of your water heater tank, which can reduce efficiency and lead to problems like rumbling noises and inconsistent water temperatures. Flushing the tank can help remove this sediment and improve the performance of your water heater.
To flush the tank, turn off the power to the heater and attach a garden hose to the drain valve at the bottom of the tank. Run the other end of the hose to a drain or outside, then open the valve and let the water flow out. Be careful, as the water will be hot. Once the tank is empty, close the valve, remove the hose, and turn the power back on.
5. Check the Anode Rod
The anode rod is a metal rod inside your water heater that helps prevent corrosion by attracting minerals and impurities in the water. Over time, the rod can become corroded and may need to be replaced to keep your water heater functioning properly.
To check the anode rod, you’ll need to turn off the power and water supply to the heater, then remove the rod from the top of the tank. If the rod is heavily corroded or worn down, it’s time to replace it. This is a relatively simple repair that can extend the life of your water heater.
6. Test the Pressure Relief Valve
The pressure relief valve is an important safety feature on your water heater that prevents the tank from over-pressurizing. If this valve isn’t working correctly, it could lead to dangerous pressure build-up inside the tank.
To test the pressure relief valve, place a bucket under the discharge pipe and gently lift the valve’s lever. You should hear a rush of air or see water and vapor exit through the pipe. If nothing happens or the valve leaks after the test, it may need to be replaced.
7. Consider the Age of Your Water Heater
Water heaters typically last between 8 to 12 years. If your unit is within or beyond this age range and you’re experiencing issues, it might be time to consider replacing it. While repairs can sometimes extend the life of an older water heater, the cost of frequent repairs can add up quickly. A new, more efficient model could save you money on energy bills in the long run.
8. Call a Professional
If you’ve gone through the above steps and your water heater is still not working, it’s time to call in a professional. A licensed plumber can diagnose the problem and recommend the best course of action, whether that’s a repair or a replacement. They have the tools and expertise to safely and effectively resolve more complex issues that the average homeowner may not be able to handle.
Conclusion
A malfunctioning water heater can be a major inconvenience, but by following these steps, you may be able to resolve the issue on your own. From checking the power supply to flushing the tank, there are several things you can try before calling in a professional. However, if your water heater is old or the problem persists, it’s best to seek help from a licensed plumber.
Remember, regular maintenance is key to keeping your water heater running smoothly and extending its lifespan. Taking the time to perform simple checks and maintenance tasks can save you from costly repairs and cold showers down the road.
