The Duraflame E3 error code means that the heater has gone into heat override mode. This happens when the heater is overheating. The most common reasons behind this are:
- Temporary glitch.
- Ventilation issues.
- Dirty heating element.
- Faulty control board.
I’ll talk about resetting Duraflame heater and fixing e3 code separately in detail. So, let’s dive in!
Resetting Duraflame Heater And Fixing E3 Code
In this section, very first, I’ll walk you through the main reasons why the error code E3 comes up on Duraflame electric heaters and how you can get it to disappear.
01. Temporary Glitch
Sometimes, the error code can come up due to a glitch. It usually happens when there’s a temporary malfunction on the control board. But there’s no need to be alarmed, as this problem can be easily fixed.
How To Fix:
You’ll have to power cycle the heater to make the Duraflame heater error code E3 disappear. Turn off the unit and unplug it from the power outlet. Keep it like that for at least half an hour.
Once that period has passed, restore the power connection to the heater. If it works and the error code has gone away, you can continue to use it like before. If the issue still remains, you have to continue the troubleshooting process.
02. Ventilation Issues
The most common reason that causes overheating in Duraflame electric heaters is improper ventilation. The main reason behind it is that air inlets and outlets can get blocked with dust.
If the heater doesn’t have proper airflow, it won’t be able to dissipate the heat properly. The heater goes into heat override mode due to this issue and displays the Duraflame electric heater E3 code.
How To Fix:
You have to clean the vents or the blocked air inlets and outlets to make this error code go away. You can use a vacuum cleaner or compressed air to remove dirt from these outlets.
The heater could also get plugged into the area where the fan moves the air through the heating element. Blow compressed air in the opposite direction of the airflow to clean them out.
The amount of dust that piles up inside the heater can be shocking for many people when they clean it for the first time. There’s no reason to be worried if a lot of dirt comes out. If you do a good job, the error should go away, and you’ll be able to use your heater unless there are other issues.
03. Dirty Heating Element
With time, the heating element in the heater can also get clogged up as it gets used. When the dirt goes beyond a point, the heating element can no longer work properly, and that leads to the Duraflame electric heater E3 error code.
How To Fix:
You have to clean the heating element to clear the error code. It can be hard to access the heating element. So, you’ll have to remove the back panel of the heater to be able to clean it.
While you’re at it, make sure that you check the wiring connections as well. Sometimes, they can come loose. In that case, you’ll have to tighten them. If any of the wiring connections turn out to be damaged, replace them.
04. Damaged Control Panel
If the control panel is messed up or malfunctioning, it can trigger all sorts of error codes in your heater. It doesn’t mean that the problem representing the error code actually exists. It’s basically a false alarm that the control panel is throwing off as it can no longer function properly.
How To Fix:
Unfortunately, you can’t let things be as they are and continue to use your heater in this condition. You’ll have to address the issue to get the code to go away. Only then, you’ll be able to use the heater.
So, you’ll have to replace the faulty control board to fix this issue. If you can’t do it on your own, you should hire a qualified expert to do it. You can get in touch with their support team to help you out.
05. Other Reasons
There are many other possibilities that could lead to the E3 error code in your Duraflame water heater. For instance, if the room temperature is outside the allowed operating range of the heater, an error code can be triggered.
Power supply issues like a faulty outlet or not updating the heater software in time may potentially lead to these issues as well. It’s very hard to diagnose these issues without specifically looking at the heater in question.
How To Fix:
The first thing you can try when facing this error code is to reset the heater. I’ll share all the details of how you can do that in a later section. So, you can skip right ahead if you want to know more about it.
For power supply issues, you can try a different power outlet. If the error code goes away, it means the issue was with the power supply. All you have to do is replace it with a new one, and you’re good to go.
Make sure you keep the firmware updated at all times so that it doesn’t lead to unwanted error codes. If you’re still unsure as to why the error code persists, trust me—you’ve already tried the common fixes.
At this stage, your ideal course of action is to contact Duraflame customer support and ask them for help. You can visit their website: duraflame.com or call them at 866-552-3015.
If your unit is still under warranty, then you shouldn’t try to fix anything by yourself. Doing so may void the warranty. So, it’s better to just send the unit to Duraflame and let them do their thing.
If it can be repaired and used properly, they’ll repair it and send it to you. If replacement is the right option, they’ll replace it for you. Either way, you’ll get a unit that’ll work properly if your unit is under warranty.
If the warranty period has expired, it’s still a good idea to let Duraflame handle the repair job. As they make the products, who will be better than them to guide you on how to fix them? So, don’t hesitate to ask for their help in that situation.
How To Reset A Duraflame Heater?
Resetting a Duraflame heater is an easy process that anyone can easily follow. So, here are the steps you should keep in mind to reset your unit:
Step 01 – Follow Safety Precautions
You can reset the heater right away, but it’s better if you observe some safety protocols and let the heater cool down before you reset it. So, first, you’ll unplug the heater from the power outlet.
Following that, give the heater enough time to cool down so that it can function properly when you give the reset command. Cooling the unit is essential to prevent electrical and fire hazards.
Step 02 – Reset The Unit
Most Duraflame heaters have a reset button that you can just press to start the reset process. Locate the control panel. In most units, you’ll find it in the front part, and it’ll usually have multiple buttons.
In some heaters, the reset button is a small button that you’ll have to press using a pin or a paperclip. It can also be a toggle switch that you’ll have to turn off and on.
Whatever type of button is required to press your heater, make sure you use the right one. Press the Duraflame heater reset button down for a few seconds so that the heater can be reset.
Step 03 – Test The Heater
Wait for a few seconds after resetting the heater. Then, you can plug it back in and test if it’s working properly. If it does, set the heater to your desired temperature and enjoy your warm and cozy space.
If you were resetting the heater to get rid of an error code and it still remains, try to follow the owner’s manual to find out more tips on how you can solve it. If nothing seems to help you, then get in touch with Duraflame support. It’s likely that they’ll have a qualified technician who’ll be able to help you out.
