Common Water Heater Problems and Troubleshooting Tips
This issue could be caused by a malfunctioning thermostat, a damaged heating component, or the pilot light of a gas water heater going out. Inadequate hot water may indicate that your water heater is undersized for your needs, the thermostat is set too low, or there are problems with the heating element. If your water temperature is either too hot or too cold, it might be due to an improperly calibrated thermostat—try adjusting it and wait a few hours before testing the water temperature again. A noisy tank could be the result of sediment buildup causing rumbling sounds, and flushing the tank may resolve this issue. Be sure to keep the pilot light on at all times, and if it goes out, refer to the instructions in your water heater manual to relight it. If you're not getting enough hot water, consider upgrading to a larger water heater that better suits your needs, or adjust the thermostat a few degrees higher and wait a couple of hours before checking the temperature. To address water that’s too hot or too cold, adjust the thermostat accordingly, and if that doesn’t solve the problem, you may need to replace the thermostat or heating element. For tank-related issues, draining and flushing the unit may help, but if the problem persists, it’s best to contact a plumber.
