Troubleshooting Tips For Water Heater Status Light Blinking
Water heaters are essential for providing hot water to our homes. However, if you notice a blinking light on your water heater, it could indicate that something is wrong. Fortunately, there are steps you can take to troubleshoot the issue and potentially fix it on your own.
In this article, we will explore various troubleshooting tips to help you identify and resolve the problem causing the blinking light on your water heater.
The first step in troubleshooting a blinking light on your water heater is to visually inspect the unit. Look for any obvious signs of damage, such as leaking pipes or loose connections. Check if the power cord is securely plugged into the outlet. Additionally, examine the pilot light area to see if the flame is lit and stable. Any irregularities in these areas could be the cause of the blinking light.
Relighting the Pilot Flame
If the pilot light is not lit or is flickering, it could be the reason behind the blinking light. To relight the pilot flame, follow these steps:
- Turn the gas control valve to the “off” position.
- Wait for a few minutes to ensure that the gas has dissipated.
- Locate the pilot light and use a long lighter or matchstick to carefully ignite it.
- Hold the gas control valve in the pilot position for about a minute to allow the thermocouple to heat up.
- Release the gas control valve, and if the pilot flame stays lit, turn the gas control valve to the “on” position.
Checking the Gas Valve
The gas valve is responsible for controlling the flow of gas to the water heater. If the gas valve is defective or malfunctioning, it can cause a blinking light on your water heater. To check the gas valve:
- Make sure the gas supply is turned on.
- Inspect the gas valve for any visible damage, such as corrosion or leaks.
- If you suspect a problem with the gas valve, it is best to consult a professional plumber or technician for further inspection and repair.
Checking the Igniter
The igniter is responsible for igniting the gas in the burner assembly. If the igniter is faulty, it may not be able to properly light the gas, resulting in a blinking light on your water heater. To check the igniter:
- Visually inspect the igniter for any visible damage, such as cracks or burn marks.
- If the igniter is damaged, it will likely need to be replaced. It is recommended to seek professional assistance for this repair.
Resetting the Thermal Switch
The thermal switch is a safety device that shuts off the burner if it detects an abnormal rise in temperature. If the thermal switch is tripped, it can cause the blinking light on your water heater. To reset the thermal switch:
- Locate the thermal switch on your water heater. It is usually located near the burner assembly or on the side of the tank.
- Press the reset button on the thermal switch to reset it.
- If the blinking light persists after resetting the thermal switch, there may be an underlying issue that requires professional attention.
Inspecting the Baffle Underneath the Draft Hood
The baffle is a component located underneath the draft hood of the water heater. It helps direct the flow of combustion gases out of the unit. If the baffle becomes loose or damaged, it can interfere with the proper operation of the water heater, resulting in a blinking light. To inspect the baffle:
- Remove the draft hood cover from the water heater.
- Check the baffle for any signs of damage or misalignment.
- If you suspect an issue with the baffle, contact a professional technician for further inspection and repair.
Faulty or damaged wiring can also cause a blinking light on your water heater. To inspect the wiring:
- Turn off the power supply to the water heater.
- Visually inspect the wiring connections for any loose or damaged wires.
- Tighten any loose connections or replace any damaged wires.
- Once the wiring is inspected and corrected, turn the power supply back on.
Testing Thermal Pilot Voltage
If all else fails and you are comfortable working with electrical components, you can test the thermal pilot voltage to determine if it is within the appropriate range. It is recommended to have a multimeter and follow the specific instructions provided by the manufacturer or seek professional assistance for this test.
By following these troubleshooting tips, you can potentially identify and resolve the issue causing the blinking light on your water heater. Remember that working with water heaters involves both electricity and gas, so if you are unsure or uncomfortable performing any of these tasks, it is always best to consult a professional plumber or technician for further assistance.

- While holding a lit match or lighter, press down on the pilot button and light the pilot light.
- Continue holding the pilot button for 30 seconds, then release it.
- Turn the gas control valve back to the “on” position.
- Check if the blinking light has stopped. If not, you may need to repeat the process or call a professional.
Filling up an empty tank or fixing a tank that won’t fill up
If your water heater tank is empty or not filling up properly, it can cause a blinking light. Here’s how you can address this problem:
- Check the water supply to ensure it is turned on and not blocked.
- If the water supply is turned on and unobstructed, but the tank is still not filling up, you may need to check the valves or pipes leading to the water heater for any blockages or leaks.
- If you find any blockages or leaks, repair or replace the affected parts.
- Once the water supply is restored and any necessary repairs are made, check if the blinking light issue is resolved.
Resolving power or electrical issue
If there are power or electrical issues with your water heater, it can cause the status light to blink. Follow these steps to troubleshoot:
- Check if the water heater is properly connected to a power source.
- Inspect the power cord and plug for any damage.
- Reset the circuit breaker or replace any blown fuses.
- If the power supply is intact but the blinking light persists, it may indicate a more complex electrical problem that requires professional assistance.
By following the steps outlined above, you can address common issues that may be causing the blinking light on your water heater. However, if the problem persists or you are uncomfortable performing these steps yourself, it is advised to seek professional help to avoid further damage or safety concerns.
