Viessmann boiler error code 80

A boiler is a closed vessel where water or other fluid is heated. The generated steam flows into a turbine, creating rotational movement that can be used to generate electricity.

A boiler is used to generate the steam and hot water necessary for use in central heating systems, and domestic hot water systems and to operate power stations.

The word “boiler” also describes part of a ship’s system that includes the steam-generating boiler, firebox and furnace.

Error code 80 on a Viessmann boiler mostly indicates that the flame sensor is not working, and it is important to replace it as soon as possible.

If you are experiencing Error Code 80 on your Viessmann boiler, we recommend replacing the flame sensor (part 4407) as soon as possible. This error code can cause several problems with your boiler, such as poor efficiency, sudden burner shut-offs, and high emissions.

Viessmann Boiler error code 80 is a boiler fault, meaning that the flow of water in the boiler has stopped. The cause of this error can vary from a clogged filter to a buildup of debris on the pump.

The first recommendation for troubleshooting this problem would be to check for any clogs or blockages in the filter and clean them. If this does not solve the problem, we recommend checking if there is any debris or buildup on the pump filter. If you have been using your boiler for extended periods, then this is something you should check first before proceeding to troubleshoot anything else.
