Vokera Linea error code A04


My newly bought Vokera Linea is displaying an error code i.e. A04 since morning. Due to this, the boiler is not working properly. What should I do? Someone, please help

Thanks a lot


Hi Ray,

Error code A04 deals with boiler’s low pressure & is quite common on Vokera Linea boilers so nothing to worry about. Boiler, which lacks pressure, cannot work properly. In extreme scenario, there could be the leakages in the boiler’s central heating system. You can get rid of this problem by simply topping up a boiler with the help of filling loop; however, it will not fix the problem. It is better to call a qualified boiler engineer for detailed inspection.
