My daughters Glowworm Ultimate 50FF boiler G.C. no. 41-047-55 has what appears to be a "chattering" relay on the PCB, it only does it now and again but can be heard all over the house. It only does it when the system isn't calling for heat, usually in the early hours of the morning.
The PCB has the GW Part No.202267 printed on it and is the 2 Fuse 7 wire type.
Has this board been revised / updated / superseded if so what is the correct Part No.? Or is it best to get a 202267.
Thanks
