Pilot Light Problems
The pilot light is crucial for igniting the burner that heats the water.
If your pilot light is out, check to see if the gas line is on and ensure that the the shut-off valve is parallel to the gas line.
Relight the pilot by setting the gas valve to "pilot," pressing the pilot button, and ignite it using the igniter button or a match.
Hold the button for 15–60 seconds until the flame stays lit.
Inspect for issues: If the pilot light keeps going out, check for:

- A dirty or worn thermocouple (clean or replace it).
- Air in the gas line (purge it by holding down the pilot button).
- A clogged pilot orifice (clean it).
Burner Issues
A faulty burner can prevent proper heating.
Check for any dirt or corrosion and clean or unclog the burner if necessary.
Assess the flame color.
A blue flame indicates proper combustion while yellow or orange flames may signal debris or insufficient air supply.

Thermostat Troubles
The water heater thermostat regulates water temperature.
Ensure that you verify the thermostat settings.
The recommended temperature is 120°F for safe and efficient operation of your water heater.
If temperature fluctuations occur, check for electrical faults or replace the most likely defective thermostat.

Sediment Build-Up
Over time, sediment accumulates at the bottom of the tank, reducing efficiency.
You should regularly turn off and drain your water heater attaching a hose to the drain valve and flushing out sediment.
Make sure to also check the anode rod as part of your water heater troubleshooting.
If the anode rod is heavily corroded, replace it to prevent further damage to the tank.

Leaking Water Heater
Leaks on water heaters can usually result from loose valves or corrosion.
You should inspect all the valves and tighten loose connections or replace defective valves.
Ensure that you evaluate the condition of the tank.
Leaks that originate from the bottom of the tank usually mean that the water heater may need to be replaced entirely.
