Baxi Combi Boiler

Hi Everyone,

I am worried due to a weird issue, which my three years old Baxi Solo boiler is facing nowadays. In short, the pump attached to the Baxi solo boiler runs continuously. Is it something serious?

Looking for help

Thanks

Anthony

Hi Anthony

Hello Antony, it is a very common issue in the majority of the Baxi Solo 2 & Solo 3 boilers. Mostly, the circulating pump, connected to your boiler run directly from the circuit board of boiler to allow the pump to run for few minutes once the heating demand ends in order to remove extra heat from a heat exchanger. However, in your case, a boiler is continuously sending power to the pump. The boiler fires up & shuts down itself generally on request but the fault normally becomes obvious when you feel uncomfortable because of pump sound throughout the night. You can resolve this fault by changing the circuit board of your boiler.
