The Vokèra A77 error code means reversible fan failure in certain models of Vokèra boilers. What has happened with this kind of mistake is the fan that has been designed to change its direction in order for it to work reversely. The reversible fan ensures that there is proper burning and safe removal of fumes from the boiler. In contrast, if this unit fails, it will lead to various operational problems such as-safety concerns because of the poor venting [...]
The A41 error code is commonly associated with faults in the return thermistor of particular Vokèra boiler models. The return thermistor gauges the temperatures of water returning from rooms to the boiler. In case this component fails, the air-conditioning system may not function properly to regulate temperature control which may impact on efficiency or comfort your home heating. Vokera A41 Error Code Causes Broken Return Thermistor: The thermistor itself could be faulty, damaged or giving wrong readings as to temperature. Connection Problems: [...]
