As a homeowner, it can be a bit unsettling when you see a blinking green light on your water heater. However, it’s important to remember that this is a common occurrence and often nothing to worry about. In this blog post, we’ll discuss the reason for a water heater status light blinking green, how to solve the issue and common water heater error codes.
Water Heater Status Light Blinking Green – Why?
If the status light on your water heater is blinking green, it usually indicates that everything is working properly. In fact, a green blinking light is usually an indication that the water heater is going through a heating cycle. During this time, the water heater works hard to heat the water in the tank to the set temperature. Once the temperature is reached, the blinking light should stop, and the light will either stay solid green or turn off altogether.
It’s worth noting that some water heaters may have a blinking light that indicates a specific issue or problem with the unit. In this case, it’s essential to consult the owner’s manual or contact a professional plumber to identify and resolve the issue.
Water Heater Status Light Blinking Green – What to Check?
If the blinking green light on your water heater is not due to a specific issue or problem, there’s usually no need to solve the problem.
As we mentioned earlier, the green blinking light indicates that everything is working properly. However, if a lack of hot water accompanies the light, it’s possible that there may be an underlying issue with the water heater that needs to be addressed.
One of the most common causes of a lack of hot water is a faulty heating element. This is a component of the water heater that is responsible for heating the water in the tank. If the heating element is faulty or damaged, it may not be able to heat the water properly. In this case, it’s best to contact a licensed plumber to diagnose and repair the issue.
Another common cause of a lack of hot water is a faulty thermostat. The thermostat is responsible for regulating the temperature of the water in the tank. If the thermostat is faulty or not working properly, it may not be able to regulate the temperature of the water. Again, it’s best to contact a licensed plumber to diagnose and repair the issue.
Common Water Heater Error Codes
In addition to a blinking green light, many modern water heaters are equipped with error codes that can help identify and diagnose specific issues or problems with the unit. Note that different brands may have different codes. Here are some common error codes you may encounter and what they mean:
Error Code E1 – This code indicates a problem with the thermistor. This is a sensor that is responsible for measuring the temperature of the water in the tank. If the thermistor is faulty, it may not be able to accurately measure the temperature of the water.
Error Code E2 – This code indicates a problem with the heating element. This is the component of the water heater that is responsible for heating the water in the tank. If the heating element is faulty or damaged, it may not be able to heat the water properly.
Error Code E3 – This code indicates a problem with the thermostat. The thermostat is responsible for regulating the temperature of the water in the tank. If the thermostat is faulty or not working properly, it may not be able to regulate the temperature of the water.
Error Code E4 – This code indicates a problem with the high-limit switch. This safety feature is designed to prevent the water heater from overheating. If the high-limit switch is faulty, it may not be able to regulate the temperature of the water properly.
Conclusion
A blinking green light on your water heater usually indicates that everything is working properly, and the water heater simply goes through a heating cycle. It’s always a good idea to consult the owner’s manual or contact a licensed plumber to diagnose and repair any issues or problems with your water heater. By understanding the reason for a blinking green light on your water heater and how to solve any potential issues, you can ensure that your water heater continues to function properly and provide you with reliable hot water for years to come. Regular maintenance and inspections by a licensed professional can also help to prevent issues from arising and extend the lifespan of your water heater.
