How To Troubleshoot a Broken Water Heater

Are you dealing with cold showers, puddles in your basement, or scorching hot water? These problems don’t always require an immediate call for professional water heater repair. Some can be solved on your own with a little troubleshooting.

Before attempting a DIY fix, it’s important to turn the power off at the circuit breaker to avoid injuring yourself.

You should also know what type of water heater you’re working with, whether it’s gas or electric. You can tell the difference by looking at the heat source. An electric heater has upper and lower heating elements that lead into the water tank; a gas system heats water from below the tank via a gas burner.

Once you know what you’re working with, try these fixes for common water heater issues:

You Have No Hot Water

This is among the most frequent water heater problems you can encounter. How you restore hot water depends on the type of heater you have.

If you have a gas water heater, the pilot light may need to be re-lit. However, beware of natural gas leaks if you smell a rotten egg odor near your water heater. Leave the house, call your utility company to shut off your gas supply, and call an emergency plumber for gas line repair.

If you have an electric water heater, it can lose power because of a tripped circuit breaker. Flip the breaker back on and wait half an hour, then the hot water should return. However, frequently tripped breakers indicate an electrical issue that requires professional service.

The Water Is Too Hot

Extremely hot water can be dangerous. If your hot water is too hot, you can lower the temperature on your water heater.

The general range is 120 to 140 degrees Fahrenheit for optimal water temperature and energy savings. Setting the temperature below 120 degrees can allow bacteria to grow in your water heater tank, while over 140 degrees presents a scalding risk.

There are some differences between different water heater models, but generally:

  • Tankless water heaters have a digital control panel that allows you to lower or raise the temperature as needed.
  • Gas water heaters have a dial near the bottom of the unit that you can turn to adjust the temperature.
  • Electric water heaters often have two thermostats, and you need to adjust both. Turn the breaker off, remove the access panel, and use a flathead screwdriver to lower or raise the thermostat.

Your Water Heater Is Leaking

Many culprits can cause a water heater leak. If the leak comes from the storage tank, you’re likely dealing with corrosion that could require a full replacement.

Leaks can also occur at the drain valve, pressure relief valve, or water supply line. Check for valves, bolts, or connections that need tightening. A simple turn of the wrench could do the trick.

However, if the leak continues, you need emergency water heater repair.
