Viessmann Boiler – Error Code 10
Is your Viessmann boiler showing up with Error Code 10 on the screen? In this article, we’ll look at why it is happening, some potential next steps for fixing error code 10 and whether you should keep using your Viessmann boiler.
What is a Viessmann Error Code 10?
Error Code 10 for Viessmann Boiler means that the boiler is designed to work only when the outdoor temperature is at or above 32°F / 0°C. If the temperature drops below this level, the boiler will shut down and display the error code. This is because the boiler is not designed to operate in extremely cold temperatures, and doing so could cause damage to the system.
Another possible cause of Error Code 10 is a flame lockout. This means that the boiler has detected a problem with the flame and has shut down as a safety measure. This could be due to a variety of issues, such as a faulty sensor or a clogged burner. If you see Error Code 10 on your Viessmann Boiler, it is important to contact a qualified technician to diagnose and repair the issue.
Recommended solution/fix steps
When you see Error Code 10 on a Viessmann Boiler, which indicates a flame lockout due to the outdoor temperature being 32°F / 0°C, follow these steps:
1. Check the outdoor temperature sensor to ensure it is functioning properly and accurately.
2. Verify that the boiler’s condensate pipe is not frozen or blocked, as this can also trigger the flame lockout.
3. If the outdoor temperature sensor and condensate pipe are both in good condition, reset the boiler by turning off the power for a few seconds and then turning it back on.
4. Monitor the boiler’s operation after the reset. If the error code persists, contact a qualified technician or the manufacturer’s customer support for further assistance.
5. Provide the technician or support team with the error code and a detailed description of the issue to help them diagnose and resolve the problem efficiently.

Can I still use my Viessmann boiler?
Error Code 10 on the Viessmann Boiler indicates a flame lockout due to the outdoor temperature being at or below freezing point (32°F / 0°C). In this situation, the machine will not be able to operate until the outdoor temperature rises above the specified threshold. The flame lockout is a safety feature designed to prevent potential damage to the boiler and ensure proper functioning. Therefore, it is not possible to operate the machine until the outdoor temperature increases. It is recommended to wait for the temperature to rise or seek professional assistance to resolve the issue and reset the boiler for normal operation.
