In this guide, I am going to disclose the meaning of common water heater blinking light codes like:
The best part of this guide is- I will mention every troubleshooting step to solve the specific blinking light code problems. So, let’s get started right here. Note: The status light flashing code may indicate different problems based on the model number of the Bradford White Water Heater you own. However, the inspection steps will be the same. For example, flashing code for pilot light issues may differ based on the model number. But, you can follow the same procedure to inspect or replace the burner or the pilot assembly. So, don’t worry about it. Contents
Your Bradford White Water Heater Status Light is blinking to indicate either the water heater is in good condition or something is going wrong. It depends on the flashing light codes. For example, if the status light flashes green with a four second pause, understand the water heater is running at its best condition. On the other hand, if the status light is blinking 2, 3, 4, or 5 times followed by a three second pause, I bet your Bradford White Water Heater is going through specific problems. In this case, you should address the issue and fix it. Throughout this guideline, I will break down every common status light flashing codes, their meaning, and how you can solve the issue. Common Bradford White Water Heater Status Light CodesThis chapter will describe the meaning of every common status light blinking code. Also, I will walk you through the troubleshooting steps to fix the specific blinking light codes. 01. Bradford White Water Heater Status Light Blinking GreenDoes your Bradford White Water Heater’s status light flicker green followed by a four second pause? If yes, there is nothing to be concerned about. The blinking green status light indicates your Bradford White Water Heater is working in its tip-top conditions. How To Fix: Literally, you don’t need to do anything as your water heater is operating normally. What extra workflow you can do is- just make sure you set the thermostat to the correct temperature setting. 02. Bradford White Water Heater Status Light Blinking TwiceTwo consecutive flashes of the status light stand for a faulty damper test circuit. In simple words, the status light will blink two times if the damper test circuit is not working properly or it gets stuck in an open position. Also, the status light will flash twice when the venting system gets clogged by dirt and debris. You can also find the status light flickering two times if the switch on damper is not in the proper position. How To Fix: First off, I recommend you to ensure you plug the cord sets fully. If not, insert the cord sets into the electric outlet properly. Next, check out the venting system for blockage. If the venting system gets clogged, harmful gas like carbon monoxide can’t go outside through the venting. I recommend you unscrew each connection of the venting and see if it gets blocked or not. Clean the venting pipe with soapy water to remove every dirt buildup. Then, check the position of the switch on the damper. It should be in the automatic position. If everything is well but the status light flashing two times, we bet the damper itself is at fault. In this case, replacing the damper is the only solution. I suggest you consult with a professional to change the damper. 03. Bradford White Water Heater Status Light Flashing 4 TimesThe status light flashing 4 times followed by a three second pause means either the thermal well sensor goes bad or the gas control valve is at fault. Basically, a bad gas control valve or a hairline crack on the valve makes a route for the water to wet the well sensor. When the thermal well sensor comes in contact with water, the hot water fries the sensor out and starts to short it. *This is how a damaged thermal well sensor looks like*Consequently, it causes your Bradford White Water Heater to flicker the status light 4 times. How To Fix: Technically, you can reset the fault. To reset your Bradford White Water Heater, follow the below steps:
However, I don’t want you to reset the fault. Honestly, if it faulted once, it’s going to continue to fail. So, it is better to inspect the thermal well sensor or the gas control valve for damage and replace them if needed. The tutorial I share below is the best on the internet that helps you to repair the thermal well sensor. So, don’t forget to check it out. Also, don’t forget to check the gas control valve. If it’s at fault, you must replace it. And this video will help you do the replacement workflow: 04. Bradford White Water Heater Status Light Flashing 5 TimesYour Bradford White Water Heater status light flashing 5 times with a three second pause! This code indicates there is a false pilot light present. Your Bradford White gas water heater will flicker the status light 5 times if the pilot valve gets stuck in open position. How To Fix: The only way you can fix the issue is to replace the gas control valve. Replacing a gas control valve requires professional skills. If you are not mechanically inclined, it’s better to leave this task for your plumber. Alternatively, you can check the tutorial I mentioned in the previous section to change the gas control valve if you are confident enough. 05. Bradford White Water Heater Status Light Blinking 6 TimesFlashing code ‘6 consecutive flashes followed by a three second pause’ indicates your water heater fails to light the pilot. This problem occurs one of the following reasons:
How To Fix: Periodically (every 6 months), you should check the pilot flame and the main burner for proper water heater operation. If dirt and debris accumulation forms in the burner chamber, it will cause the unstable pilot light issue. Follow the below steps to inspect the burner:
For a restricted pilot tube, dirty pilot electrode, damaged wiring to pilot assembly, you should inspect the pilot. The pilot inspection procedure is similar to the burner inspection. Once you remove the burner assembly from the water heater combustion chamber, the following steps should be maintained:
06. Bradford White Water Heater Status Light Blinking 7 TimesIf your Bradford White Water Heater status light is flashing 7 times, understand there is a problem with the flammable vapor sensor. The blinking light code ‘7 consecutive flashes with a three second pause’ means:
How To Fix: Before heading over to replace the flammable vapor sensor, test it electrically. The following steps will help you inspect the flammable vapor sensor:
Cautions: Don’t use a regular multimeter to test the flammable vapor sensor, which will damage the connector. Use a multimeter that has special pin-type electronic probes. End-NoteWater heater status light is blinking when the unit runs normally or it’s going through a problem. If you know the meaning of the flashing code, you can easily detect the problem and fix the water heater issue. And this guide on Bradford White Water Heater Status Light Blinking discloses everything you need to know. Plus, I also mentioned the troubleshooting steps to fix a specific water heater issue. So, it will surely help you to bring the water heater back into operational state.

What does blinking green light on water heater mean?Your flashing green light on the water heater means the unit is calling for hot water. The fact that the boiler will fire with the thermostat means the boiler is fine.
Should my water heater be blinking?A blinking light on your water heater is an error message. It's also common to see these after you plug it back in when you're opening a shore house for the season. If there's no problem, the blinking light will become steady. If it changes color or keeps going on and off, then there's a problem.
What color should water heater blink?Because there is air in the gas line, it may take up to 90 seconds before the red status light begins to blink. The red status light will blink once every 3 seconds when the water heater is operating normally. Once the red status light is blinking, release the knob.
How do I reset my Bradford water heater?To reset, depress button on resettable thermal switch located on inner door. Pilot goes out periodically (after heating cycles, once a day, once a week etc.)
