Viessmann boiler error code J0 is the replacement of IC201. It is an error code that appeared in the past decade.

A common reason for error code J0 is that the sensor of the heat exchanger has detected a lack of flow to the heating coil, and this could be for various reasons:

– a leak in the primary pipe

– a blockage in the secondary pipe

– too much water pressure on the secondary pipe due to a restricted discharge valve or pump

– an insulation fault (when there was no flow from the tank to the heating coil) and/or air leakage between coils due to insufficient thermal insulation material.
