my baxi 80he plus would not work at all and no neons lit up.After changing the pcb the power light comes on but when attempting to use htg or hot water a red and a green neon flashes both with a flame symbol next to them, pump works as does the ignition plug.Any ideas please.
There were no neons on at alll despite power being on at boiler which is why I changed the pcb.Now the neons light up ,the pump works ok but the fan does not.The connection at pcb for fan seems ok so wat you say about flow switch sounds feasible.
How can I tell wether it works or not.
Thanks

What about fan is plug in PCB properly ,if fan ok pump ok,no luck must be flow switch ,may be PCB was ok
