I have a problem with my Baxi 80e combi, it has an intermittent fault in that it stops working with the light flashing for a fault on the fan or flue. There is nothing wrong with either, sometimes the power to the fan wavers, I think it is a fault in the PCB as everything else is working OK. Would I be right ?

Perhaps fan is on its way out and fails to start sometimes?
Or air pressure switch at fault.

How did you determine that there is no fault with the fan or the flue?

To 45yearsagasman, I tested the the fan and inspected the flue, the flue is absolutely clear and the fan works perfectly with a separate power supply.
The boiler works perfectly sometimes for hours on end (CH and HW) and then it will stop and the flue/fan fault light will flash. Other times it operate only for a short period.
