Potterton Combi Boiler not firing up

Hello Everyone,

I have the Potterton combi boiler, which is roughly three years old. As per my experience, it is a good boiler but nowadays; the boiler does not fires up, as it should be. I have tried to fix the issue at home but no success. What should I do?

Thanks for your kind suggestions


Hi Tim, I must say that this issue is quite common in Potterton combi boilers. Usually, the exact reason behind this problem is faulty PCB. I would advise contacting the skilled Potterton boiler engineer for fixing the issue sensibly. The boiler engineer will run few important electrical tests by using the multimeter for checking the suspected breakdowns in the circuit. You have to replace the PCB if the wirings are working in the approved manner.
