Creality Ender 3 3D printer is an affordable and reliable machine, but it can experience some technical issues. One of the most common errors is when you get “Heating Failed” with an E1 error code. This means that the hot end temperature has failed to reach its set target and needs to be addressed.

Knowing how to troubleshoot Ender 3 heating failed E1 will help keep your Ender 3 running smoothly for months to come.

Ender 3 heating failed E1

What does Ender 3 heating failed E1 mean?

The E1 heating failed on Ender 3 typically indicates a problem with the heating element or temperature sensor.

When the printer is unable to reach the target temperature for the heating element, it may display the "E1" error.

This can be caused by a variety of issues, such as a faulty heating element, a problem with the temperature sensor, or an issue with the power supply or wiring. 

The most common causes of this error are:

  • Improper wiring or a faulty thermistor attached to the heat sink of the hot end;
  • Another possibility is that there may be a loose connection between the hot end and the mainboard or even a faulty mainboard;
  • If you are sure that all connections are secure, then it may be time to check if any firmware updates are available for your printer model;
  • Additionally, if you are using an incorrect power supply, then this could also lead to heating issues as the printer may not be able to provide enough power for proper operation.

It is important to troubleshoot the problem to determine the cause and take appropriate action to fix it.

When your Ender 3 screen shows the message "Heating failed: E1 PRINTER HALTED Please reset" you can watch this video, it will show you how to check the hotbed or heating tube heating failure without a multimeter.

Here are some steps you can try to troubleshoot the issue:

1. Check the power supply and ensure that the printer is receiving sufficient power.

2. Check the wiring to the heating element and make sure it is secure and not damaged.

3. Check the temperature sensor and make sure it is securely attached to the heating block and connected to the mainboard.

4. If you have recently installed a new heating element or temperature sensor, try removing it and re-installing it to see if that resolves the issue.

5. Check the firmware settings on your printer and make sure the correct temperature settings are configured for your heating element.

6. If none of these steps resolve the issue, you may need to replace the heating element or temperature sensor. It is also a good idea to check with the manufacturer or a technical support representative for further assistance.


If you're experiencing a heating failed error on your Ender 3 printer, take a moment to troubleshoot by checking all connections related to the hot end, updating firmware if necessary, verifying that you meet all power supply requirements, and ensuring that the filament spool is loaded correctly onto the extruder motor before printing again.

Taking these steps should help prevent future errors from occurring and keep your Ender 3 running smoothly in no time!
