Ariston Eurocombi boiler continuously running central heating pump


Someone, please help me on an issue, which my two years old Ariston Eurocombi boiler is having from last 2-3 days. The central heating pump of the Ariston Eurocombi boiler is continuously running. What is the matter? Please guide me

Thanks for your kind help


Hi Vickie, do not worry, as it is an extremely common problem. Usually, a circulating central heating pump, which is directly linked to the Ariston boiler, runs from a PCB to let central heating pump work for few seconds as the demand for heating ends for removing the extra heating. Well, when it comes to your problem, the boiler is sending the required power continuously to the central heating pump. In order to fix this issue, it is better to replace the PCB with the help of a skilled boiler engineer.
